I'm growing two feminized strains , critical and cookies gelato.
My plants are two weeks old have started to yellow on the edges of the bottom leaves. Watering is around 6.5ph and my humidity fluctuates from 50-65%. But generally in and around 60% rh. 18/6 hour cycle
Temperatures are going between 19°c with lights off and 30°c light on
I'm using bio-bizz all mix and have them potted in a 12L fabric pots.
The first plant to start was the critical, it started with slightly off green then turned light green, then yellow, then kinda brown (pictures to show)
If any info is there on wether it's just a deficiency that can be corrected or if it's a disease that would greatly help!
First picture is the critical after about 3 -4 days with this issue
2nd 3rd and 4th pics is the start of it on the cookies( 4th pic easier to see that the rest hard to see but something's up!)
Also right now they do need watering but they're about to go into their night Tim so don't want to water yet.
How close is the light whats the lux ? Get a iphone or android download a lux meter and check your lux from the top of the plant. Its prolly way too high.

Then its wind burn would be my guess, both those look the same tho so its hard to say.. 3 feet with a 250W hps should be more then high enough so that should rule out light burn :D
So wind burn? You got a fan pointing at them or bouncing right off a wall and hitting them?

Yeah I was thinking definitely not light burn!
I got two fans running on low setting pointed away from them but there is a small breeze coming towards giving a very slight rustling, I read that helps them strengthen their stems and helps air flow.
But I won't rule it out I'll move the fans higher and see.

YES both problems at the same time ROFL which is why i couldn't say for sure.
Got my light problem fixed but still had a lil bottom leaf discoloration like yours finally realized the damn lil fan was bouncing right off the wall onto the plant.
Its a balancing act trying to get air circulation without directly hitting the plants i know..I ended up pointing a 2 fan system straight up and let the passive air intake work its magic plants get a lil breeze without any real direct wind contact to worry bout.
But yeah if its not the lights its the fan :D Good luck lemmie know if i was wrong lol
