Hey, I'm pretty sure my plant is N deficient. She has been yellowing quite fast on the lowest older leaves over the last 2 days and the tips are feeling dry. I just watered (without nutes) 2 days ago and dont feed til 3-4 days after watering. I'm wondering If I can give them nutes sooner than usual and if so how?? Or do I have to wait until the next feeding and just hope she's not too far gone?

Growing in Coco, 9inches under a 400w MH

they look like they have been overwatered a touch too mate, let them dry out and then give them some nutes.

If I am right you are feeding only GH Micro and a similar product with the same 5-0-1? My advice would be to get a product with a balanced NPK. I doubt its a N deficiency due to the 5-0-1 you are feeding them. Try the new balanced NPK in a folliar dose which will be on the bottle. Do it right before you shut the lights down for the night. Mist the undersides of the leaves. I bet this helps. Put a drop of baby shampoo or dish soap into the folliar solution to act as a wetting agent. Do not use antibacterial dish soap. They sell the wetting agents at the hydro shop also. Example is Advanced Nutes Wet Betty. Keep it simple. Remember to filter out the bullshit you can read here. Its not your ph or your ph runoff.

I don't know if it being before the light cycle starts would be part of the droop, but I've been pretty good about my water sched... And would over watering cause dry tips?

I think the other bottle he was using is BC grow.

He's growing in coco. Asking what his runoff is in this case would make no sense. (not sure why the guy asked in the other thread for this plant)

If its not an N def, then what is it???

 

[Illegal Wonder]

BC Grow 1-3-6 npk is the main nute I'm using, and CalMag 2-0-0 with the Micro 5-0-1

Yes it is, glad to see you on my new thread. The yellowing since last night is worse and now the leaves are going brown, just the bottom 2

 

[fandango]

just try a transplanting into fresh mix and bigger pots

 

[Xub420]

let em go, and continue your journey.

9 inches is very close for vegging with a 400w. Coco is inert (unlike soil) so you should use coco nutes with every watering. Just make sure you start with very low doses and work up.

 

[churchhaze]

Geeze people. Stop telling him to change out the coco!!! That makes absolutely no sense!

Let the leaves go, or the plant??

 

[welshsmoker]

can you check your roots mate?

I had it at 8'' for weeks and had no heat issues. Posted the light height many times also and you are the first person to comment on it being too close...

How do I check the roots without transplanting?

 

[lahadaextranjera]

Raise the lights, let it dry out and re-start with the feeding at low dose. Bottom little leaves like that are supposed to die away. Concentrate on new growth.

There's always a first!!!! In Spring time (when plants are vegging in the wild) we don't have extremely strong sunshine but the light hours of Spring and sunny rays are enough. I'd put veg HPS lights about 40 cm minimum to over a metre for new clones that are transplanted.

I think Gandalfdagreen did hint in his answer that there is nute deficiency, yes. And over-watering can cause dry tips or even the whole plant to wilt, all depends on how many roots rot off mate. You wanna dry out those roots a bit, and Mr Dagreen suggested a foliar feed just before dark for two reasons, first it works best when a bit colder so literally right before lights off is a good time, second they'll respond faster than with a normal feed, plus you won't change the nute content in your soil.

The dude always gives solid advice all over the forums, trust him bro.
