Need some help: heat stress of toxic?

[Ottoman]

http://www.icmag.com/gallery/data/500/Picture_705.jpghi guys newer to this site and I have a question:

My veg room has been a nightmare the last month or so I have had 5 of my mother plants get so bad they died and i was only have to get clones from 2 and so far only 1 has rooted. I haven't chnaged my feeding schedule or brand of coco for over two years and I have never had this issue so i dont think its a PH problem.

I have a 4x4 tent with a 400w MH on 18-6 with a house fan inside and exhaust fan on top. My room temps are obviously higher than normal 85-90 during day 80-85 at night. Usually my mother growth just stunts but now they're doing something different. Any help is much appreciated.



this one is about to be the next dead mom

Looks like you might have a little heat issue (i see a leaf with the edges pointing up), but I wouldn't that it's that severe enough to cause your issues. I've seen edges up like that and grow just fine. Dunno what the deal is, but could have gotten some bad in that soil. As those moms from seed or are they from clones?

They were all from clones
