Are you growing in coco or soil? Have you been giving them nutrients? Whats your schedule if you are? How far are the lights from the plants? Whats the temp and humidity like?

Yes in coco gave nutrients yesterday light 1000 w led running at 70% move light from 36 to 22 inches away. had 2 dropping 1 at back looking a lot better now temp around 22-24C hum 50 watering is messed up not drying out very fast think it was about 4-5 days between water and feed but still was damp when feeding yesterday any help u can offer is much appreciated :+1:

Had 2 like this gave them nutrients yesterday and second 1 is looking at lot better now but I’m still unsure with the 1 in pic

If you’re in coco, you can water everyday. Im on my 3rd indoor grow, first 2 was soil and this 3rd time im in coco. I was constantly over watering in soil… I alternate water, with cal mag, and nutrients, with cal mag, daily. When they were in 1 gallon pots i gave them .5 liter a day and now that their in 5 gallon pots i give them 1 liter a day. I get at least 10% run off with those amounts. If you water every day, you want to make sure you get at least 10% run off. Especially if you’re not giving organic nutrients. Its almost impossible to over water in coco, so i think they’re drooping because they lack nutrients. I think you should also get your humility higher. Like 60% to 70% at this stage. I give co2 so i run my temps higher, but i average around 85 to 86 f and about 65 to 70% humidity and that puts me in a good vpd range. I love coco. Its so much better than soil for new growers becauae its so forgiving. Up your water and feeds and i am sure you will see them bounce back with explosive growth! Happy growing! First pick is 26 days ago and 2nd is yesterday.

Think lowering light has help aswell

@aman_rndhw has good advice about increased feedings

If you’re in straight coco you might as well take full advantage of it . . . don’t worry about pots being heavy . . . worry if they get light/dry. You should feed them to runoff everyday to see them take off. Depending on container size I feed up to 11 times a day in flower . . . starting with single feedings as the seedlings move into the veg stage and adding shots as they grow and process nutrients faster.

Feeding to runoff every time flushes the leftovers out and ensures plants have fresh nutrients without having to worry about a deficiency or build up to cause problems.

Remember, coco is pretty flexible . . . but treat it like soil and you may not be very happy without some amendments . . . treat it like a hydroponic medium and you get hydro like results.

11 times! This is my first time in coco and right now i am alternating between water and nutrients every day. I think i might flip to flower this weekend, or on monday, but within thr next few days. Once i am in flower, do you think i should feed and water everyday once in am and once in pm? Growth in coco feeding daily vs growth in soil, not even comparable for me!

It really depends on the size of the pots and plants . . . the biggest container I use is 3 gallon, those I feed 3-5 times a day in flower, number of feedings go up as container size goes down. Bigger plants in smaller containers need more feedings, I’ve tried flowering 3’+ plants in various size pots, from 1L - 5 gallon. I feel that 1 or 2 gallon are the best for me. I do transplant, normally just once and only because its something of a waste of nutrients to feed plants in a larger container than needed.

As for alternating feedings . . . I’ve talked to a few who do that, but they always add calmag even if not giving anything else. Coco is a calcium hog so I’d probably give it some thought.

Ok thanks noticed this today any ideas


What nutrients are you feeding? Just seeing those leaves, they look hungry to me. Ensure your pH is in range and you may want to bump calmag a bit also, the spotting could be early Ca deficiency showing up. Any twisting or odd look to new growth?

I see. Mine are in 5 gallon, so hoping once a day is good for now. I just flipped to flower last night. I give cal mag every time i water or feed. Mine seems more like a mag deficiency since its light green/yellowish inbetween the veins of the leafs. Gonna give a cal mag foliar for a couple of days see if that works. I had a lot of twisting odd growth early on in this grow. I used the canna bricks and they were buffered so i thought i didnt have to give a full does of cal mag. Havent seen any growth like that lately so must be getting better.

Biobizz grow/top max/bloom 2ml of each per liter and 1ml calmag per liter but was only given with nutrient feed will do ever day now them spots have spread fast only seem to be on 2 of the leaves

@aman_rndhw Once a day should be fine in 5 gallon . . . are you hand feeding or on pumps and timers? If auto feeding I’d do 2-3 a day . . . sounds odd but you get it right and you’ll use less nutrients by feeding more often. With shorter dry back times and multiple feedings you hit runoff quicker rather than half a gallon just to get it wet again.

@Greenmachine81 I don’t know anything about the Biobizz line personally, but I’d add calmag full dose every time, water or nutrients. A light foliar supplement for a few days would likely be a good idea also. I see a bit of dry coco around the edges . . . are you hitting 20% runoff with every feeding?

I am hand feeding. I will keep an eye on thrm and bump up to twice a day if needed. If i did that, would i still alternate days, or would i water and feed daily, or water twice a day and then next day 2 feeds?

I do nutrients in all water . . . every feeding, everyday. I think you should be fine at 1 feeding daily in a 5 gallon bag . . . as you said, bump feedings if you see problems.

For future grows I’d consider smaller containers . . . just no need for anything over 2 gallon, 3 at most running coco. Pretty simple and relatively cheap to set up an auto system to feed multiple shots . . . runoff removal is usually a bit more difficult unless you have a floor drain nearby.

Oh. So you dont alternate between water and nutrients, you just mix your weekly ratios in a big res with how much ever water is needed for that week? Do you lower your ratios or feed recommended amounts?

Ok, i will do max 3 gallon next time and see how that goes. Want to fit one more grow before summer. I will check out the auto feeding set up. See if i cant put something together. Thanks!

I usually mix 10/15 gallons at a time, one reservoir for flower, one for veg . . . pumps and timers take care of the feeding. Nutrients in all water. I don’t modify the ratios, the folks in the labs do the experimenting. When mixing nutrients I’ve found it best to follow a good feed chart, either from the manufacturer or other reputable source. A lot of people complain that these formulas are too hot but that’s not exactly correct, the formulas provide the correct Nutrient Efficiency Ratio (NER) for plants at a given stage, NOT the correct strength of the nutrient solution to be given to the plant. That is determined by measuring EC and diluting until you get the strength you want . . . a seedling formula and a veg formula may be the same as far as NPK ratios but very different in strength.
