First Coco Grow

I have a thread going but, I was unable to upload the new pics. How are they looking? The 3rd pic concerns me it is droopy but, not sure if it is over/underwatering or something else.

Any advice on the rest or are they looking ok?




I watered them yesterday with 1/2 strength (2ml per liter) of "CANNA START".


Pictures with no lights on:

They look ok to me, only concern might be overwatering due to size of the pots, best of luck!

seems like overwatering. cut back on that

This is where they are at now.

1) Any idea what the first twos (it is the same plant)problem could be? Some leaves or curling cupping up. I thought it was being under watered but, the soil is moist. I have also raised the lights but, the rest are good so I do not know if that can be the problem.

2)The last two plants are really small and they were started at the same time bad genetics? just slow growing?

Thanks.

I have read that 15-20 % run-off is wanted however, is this changed depending on pot size? If you have 2-3 week old plants in 3 gallon pots would watering everyday to 15-20% run-off cause potential over watering problems?

I never even considered that.

yes it would, cannabis is not a swamp plant it does not like constantly moist soil. Cannabis likes to be fully watered and then dried out nearly completely before being watered again. if you water everyday and keep the soil wet your plant will nto be happy and can develop problems quickly

Bump...Any thoughts on the new set of pics? Especially the curling/cupping.

I do believe you were answered james. you're over watering if you're watering everyday. roots take in oxygen from their roots so if you're constantly watering you're suffocating them, how long would you survive under water? hydro is totally different due to the fact airstones are in the water for o2. Just listen to the guys above (you're over watering) what i do is remember how heavy the pots get when i water, once it starts feeling light I know its getting dry. I stick a finger about 1 inch deep and see if its dry or moist then give water. to each op their own bro, not tryna be offensive just don't want you to off ya plants by drowning it.

Thanks guys. I did not water yesterday/raised the lights and the plant looked good the curling has for the most part gone away. However, today in the morning it looked like this. What could cause this high humidity? Under watering?

it still looks over watered, probably take at least a few days to see a change

Any idea what can be going on especially the curling in the first two?

The flash may have made the leaves look a bit more yellow but, it is there.

I have stopped watering everyday and just starting feeding nutes the day before yesterday at around half strength. 1.5ml per liter of "canna a/b" and 2ml per Liter of "rhizotonic".

What is the pH and EC of the nute solution?

It needs to be between 5.5 and 6.0 and best to pH it on the low end of that spectrum because as the plant eats the EC in the root zone drops and the pH ruses allowing the roots/plant to take up all macros and micros.Treat coco coir as a hydroponic/soiless medium...pH 5.5 so as it feeds and EC drops the pH rises to 5.8/6.0

I water/feed at 5.7-5.8
