Update: I think everyone was right about burning.. so apparently both our bluelab pens are wrong, they both read 1.8, but our new apera ppm stick reads 3.5... I've never thought that two pens could be off by 500-1000 ppm at the same time. I still think we have a fungal problem but we will see if...

Update: things have gotten worse, lost half the room, seems like the half of the room the ac is on survives.. could be a heat stress issue..?

I really don't think it's a over fertilization. When your plants burn, they start at the tip of the leaf. Like this picture. These tend to start on the outer leaf sides and works it's way in like a deficiency.. correct me if I'm wrong. We water less and turned the humidity to 80%, showing...

They started out healthy

Run off is 900 ppm, 5.9 ph. I'm beginning to think it was a over watering issue as this coco substrates comes super dry and water logged after accepting water. It seems only the first batch of clones were affected due to over watering. The new clones potted 3 days after haven't been affected...

Room is ac/c02, c02 around 800 Water is r/o, this is a thailand grow btw Oh yes I also use cal-mag

Same lights, hps dimlux

I'd think they are, last batch we went 600 ppm same issue, we have 0 issues in the small room, but this big room has been plague me to death.. athena recommends 1500 ppm all through

70% coco 30 % perlite

Lower old fan leafs curling, then turning brown. Temps ans humidity 80 degrees, 60 humidity Using athena pro, bio root, rhizo blast. Ppm @ 1200 ph @ 6.0 Starts healthy, problems starts at day 5-7
