I'll post up the trouble shooting form soon. The soil is pretty hot, haven't checked the temp but the air temp is now 87deg w/ac, was 89-91.5. I think a lot of it has to do with heat stress but now I'm really close to the 86 degree air temp recommended with co2 enrichment.

I meant "hot" as in "having a lot of nutrients"... my bad for not clarifying.

And I only saw this in young clones... after about 1-2 weeks, everything started to look normal again. I wasn't sure if it was pH or nute-burn... but I think it was nute-burn from the FFOF because the pH wasn't that high (7.2 - 7.4 in soil). But I've since gotten it down to right around 6.5 or so....
