What strain are you growing? Is it Auto Quick One by RQS
Are you growing Indoor or outdoor? Indoor
Are you using nutrients? Which ones? How much? So far two feedings 1/8 recommended dose twice recommended dose is 1ml.

Hi all,
First time growing here. My plants have been fine up until yesterday. My smaller plant started showing signs of what I thought was over watering. So I put on the extractor fan to full to try dry it out as medium was still damp under the surface.
Now today my bigger plant is showing limp droopy leaves signs now and new leaves beginning to claw or curl to.
Basically I’m a newbie an I have no idea what it is - to me it seems like it could be either of the following - underwatering ( as the second plant is now showing signs after I tried to dry out the medium)
Nitrogen toxicity as leaves are still green but begining to curl, but I’ve only fed twice 1/8 of a ml mixed and phed in 200ml then each plant 100ml solution.
Heat stress - but my temps are staying between 24-27°celcius.
Hi Gunter, welcome to the community!
Can you post the link to your Growlog so we can take a closer look?
To share your Growlog:
In the Grow with Jane app, tap on the plant’s name
Tap on the Growlog icon at the top right corner and Share
Copy the link here
The curled leaves could be a sign of underwatering but also you mention droopy leaves, and that could be overwatering ending in a root issue. Pass your Growlog so we can look at the pics and help.
They’re looking healthy. I’d use a stick as a guide since your plants are all falling.
How big are the pots you are using and how much water do you feed them?
If the top soil is dry, that doesn’t mean the whole plant is, that is the first area that gets dry. You can stick your finger in the soil and check its humidity.
Thanks, I have started LST with both plants thats why they look like they have fallen over. Some of the new leaves looked a bit deformed or clawed to me?
Both are in 11L pots in a coco/peat soil mix. last time i gave 100ml per plant which i didnt think was too much but seems like its taking long to completely dry out.
thinking of drilling some holes in the sides of each pot to increase air flow/drainage.
A bit dry? Still seem droopy to me in the top newest leaves… and light green in colour. Seems like they droop because the soil holds too much water, then when I leave them dry out, they droop again from too little water… (watered again yesterday btw 100ml per plant, soil is still wet/damp underneath top soil)
Okay, I thought I had this figured out as a nitrogen dificiency as they bounced back slightly after 2 feeds, but lower leaves are turning even more yellow and getting brown spots.
Upper newest leaves have yellow streaks, and there are random brown spots/holes on some leaves… I’m lost.
From reading a lot of articles online it looks as if it could be a magnesium deficiency? The coco-soil mix I’m using says it doesn’t contain a lot of nutrients and I’m not using CalMag as I thought regular tap water was sufficient (any truth to this?).
At this point I’m not expecting these girls to survive, but really want to get to the bottom of it to avoid this in the future. Very frustrating thinking you have it solved and then seeing them wilt even more!
Coco Coir has no nutrients and in my opinion you would need a great deal of experience supplying nutrients with purchased products. You would be better to go with a potting mix. I like Fox Farm’s Ocean Forest. You can still feed your plants with additional nutrients, but even if you dont your plants will grow wonderfully as long as you repot at appropriate times. The idea that water contains nutrients is true with hard (well) water. However, you will need a PPM pen to determine how hard the water is and the harder it is the more ph UP and DOWN it will take to adjust. The other thing is, you will still not know how much and what % of minerals are in it. Soft water from a softener will contain a lot of sodium and I would not use that. With tap water (city) you will not know what is in it either. Therefore, it is best to use reverse osmosis or purified water and add your nutrients.
Thanks Outdoorman, it’s a coco/soil blend I’m using with the below ingredients:
White peat
Dark peat
Coco coir
Perlite
Worm humus
So it’s not pure coco coir as such. I’ve stupidly just realised that I have been measuring my feedings incorrectly the whole time… I was reading the syringe wrong adding .05ml or .10ml per litre rather than the recommened .5ml or 1ml per L as per manufacturers recommendations…
So it makes sense that I’m seeing a nitrogen deficiency now and signs of magnesium/cal/zinc deficiency as a result of that (as I’ve been reading these can be secondary effects of lack of nitrogen). I’ve given a full dose of my veg supplement now to each plant so hopefully they pick up. Unfortunately they’re autos so I’m not expecting miracles.
Hello! Although your soil mix has other ingredients, coco seems to be the main problem here. Coco mixes take most of the calcium and magnesium from a nutrient solution or water before the plant is able to absorb them.
This leads to calcium and magnesium deficiencies, which your plants seem to be suffering. A Cal-Mag supplement is key when growing in coco, consider adding one to your nutrient schedule.
Growing in coco requires a lot of research and experimenting until you find the perfect balance and, as Outdoorman said, you need to measure lots of things, such as EC and pH. Measuring these would help you to have a better idea of what’s going on with your plants, but if you don’t have the equipment, it’s just guessing. Growing in coco is definitely not recommended for beginners.
Now, let’s try to get the best out of this situation. As you said, you’ve been applying a very low dose of Crecimiento Boom and that leads to deficiencies. The manufacturer recommends applying 2ml/L to fix macronutrient deficiencies. Also, you may spray your plants with a 2 ml/L solution now and see if they respond well. They claim you should be able to see changes within 24-48 hours.
Quick One is a fast growing autoflowering strain, this means they complete their cycle in 8-9 weeks. Now, they are starting the flowering stage, so they probably also need flowering nutrients/supplements. Consider adding them to your nutrient schedule as well.
For next time, try growing in a soil/peat mix, with perlite and humus. This will be much easier to manage, nutrient schedules may be a lot easier and you can concentrate on learning other basics of growing Cannabis. Also, for small-sized fast-growing autoflowering strains it is not recommended to train them like this, it may stress them out and cause stunted growth. They grow better and bigger with little or no training, just a slight defoliation may be enough.
Thanks for the extensive post, this is definitely a learning curve!
Got it, I’ll leave the coco mix out next time so. Are peat mixes the same or are they counted as soil mixes? Also add 10-20% perlite for drainage right? Looking at Canna Terra Professional for next time.
Peat has no nutrient qualities. Its main quality is that it holds ten times its weight in water. Perlite and vermiculite add space to allow for aeration. Bark fines provide the same. Worm humus is the only nutrient you mentioned. It would be better to purchase a potting mix (not planting mix) as I suggested above, which contain the ingredients you mentioned plus: bat guano, shrimp, fish, kelp, and possibly other nutrients; hence the name “Ocean Forest.”
I just checked out that product and they are designed to be used during the appropriate stages of growth. Use the Canna Terra Professional for the first three weeks planted in party cups. They should be ready for transplant after 3 weeks and then transplant into the Canna Terra vega (veg stage). You will need to transplant again during this stage. When you begin the flowering stage transplant into 5 gallon pots using the Canna Terra Flores. Each product is designed for the individual stages and therefore provide a different set of nutes.
Can I just use the one type of soil and use different liquid nutes (veg, bloom etc.) as needed? I’m growing autos for now so not keen on transplanting.
