Hello prople. I just wanted to show off one of my babies, and might also ask for some opinion on those leaves. I think it was caused by lack of nutrients, mostly because it stopped advancing when I fed the girls 
Thanks for reading and I’d appreciate any comments!
Have you checked your pH? I had a similar problem on my last grow and it was low pH which caused nute lockout.
Your environment temperature is above 31°, that is way too high, you need to low it down to 27 at least.
Also, the humidity went from 48% to 73%, its a bit high, I see some leaves burned at the end, have to work on that environment temperature.
I see some differences between the waterings, you feed with 350ml, then 100ml, then 200ml and 750ml.
What kind of pots are you using? Do they drain the water properly? That could be causing the high humidity mix with high temperatures, and you see the result.
I know about the temp and RH, but I can’t do much about them for now. I’ll see to make some changes on the indoor, first of them being install fans again(I currently trust air extraction to the power source’s cooler fan)
It’s good to know that having the tip of the leaves a little burnt could be from enviroment temp. I have currently no good way to measure soil pH, but I do make sure to measure pH for water and nutrients around 6.5.
Pots are made of fabric, so they drain from everywhere. It’s my first time with autos and I didn’t want to overfeed them. Also watering was irregular because of the temp and low humidity for some days, causing them to dry quicker than expected.
Thanks for your comments!
If you are working with only an air extraction then you need to add fans, that will drop the temp and generate a better airflow, they won’t be suffocating anymore.
The burned tips could be many reasons, but I think it all points out to the airflow and environment temp.
You are using Led 100W and 20hs of light exposure, that seems to be fine since the led lights don’t generate that much heat.
Just add some fans if you can, and give it like 4 days to see how it develops.
I’ll add them as soon as I can, most likely after harvesting these 2. I’ll take the time to plan properly where to install them and wich fans. Thanks for the advice!
