Need Help With Diagnosis! Bleaching/nite Burn??

[Cannabisseur]

Hello fellow farmers! I need some help to diagnose what's going on with me ladies! I have 12 clones vegging in a 3x3x2 DIY grow box with a 24" double T5 and two regular say, 50w cfl 6500k bulbs. The clones are in fox farm happy frog soil and I have only been feeding plain R.O bottled water for the last couple of week.

The problem is that some of the girls are developing bleached leaves and some are getting discoloration, dark marks, and even spots that look like nute burn. Some of the new growth is a super light green, almost yello yellow color.
I had the T5 about 4" away from the girls and just raised it to about 8 inches. Hoping that works.

Also, I've used FF happy frog in the past for my outdoor grows and I haven't experienced nute burn from the happy frog, but I believe the bag had been sitting for a good while at the hydro shop before I bought it. It is a small bag not the regular 2c.u but the small bag that still says organic on it. I've noticed the newer big bags of happy frog no longer say organic just natural.

Anyways, any help or suggestions needed and greatly appreciated please!!!

Jah bless!!

Title is suppose to say NUTE burn not Nite. Stupid auto correct.

I'll post pics in a minute.

This is the new growth really light green almost a yellow. The leaves seem to be curling under also.

More greenish-yellow new growth.

This one has bleeching like properties on the leaves.

This one looks like nute burn on the edge of the leaf. Also has some discoloration.

• This one is weird looking it has discoloration but its different than the rest cause it seems like it has darker spots or marks.

On the third pic you can see a dark mark right above my finger nail.

The temps in the box average from 75-80 and humidity from 55-70.

I have a small fan inside but no intake or exhaust yet. The lights are on 24/7.

Any other info or questions you have let me know but someone please help soon!

Thank you fellow farmers. God bless.

Thinking about getting a new bag of happy frog and just re-potting all the ladies. Probably get a bag of perlite and do a 50/50 mix.

Thats not bleaching bud....not even close

What do you think it may be?

The stems are very purple and the necrosis is likely caused by deficiency not burn .

They look over watered as well

 

[Cannabisseur]

Thank you organix. I guess some of the girls must be heavy feeders like the WiFi's because I've used nothing but water while using FF happy frog for other strains outdoors and had not needed to feed until a month or two after transplant.

I usually wait till the soil seems dru to over water, but ok thank you I will keep an eye on the watering.

 

[organix4207]

It could be that u are using ro water and no cal/mag added. I've never used fox farms soil so can't really speak on it

I looked close at the pics and the soil doesn't look to wet in pics. The droopy top growth is usually a dead give away for to much h20.

 

[Cannabisseur]

Yes that's exactly what I was using, bottled r.o water plain with no nutes.

 

[Cannabisseur]

So I went out to the hydro shop and picked up some nutes. Didn't expect to have to do this till a couple more weeks. But I guess I had my outdoor mentality.

 

[Cannabisseur]

I know its a possibility that they are over watered, but I added grow, cal/mag and bioweed to the water and watered them a tiny bit. Hope this helps!
