Sick Purple!

I've got 4 New Purple Power from Nirvana seeds and one bagseed growing in 2gallon-5gallon pots of FFOF soil. The plants are anywhere from 2 weeks to a month old. Temps are usually 80-82 under a cooltube and 400w HPS running 24/7. These plants have seen the mid 90's for about 8 hours until i realized how hot they were. I'm using tap water run through a brita filter which brings my PH down to between 6.0 and 6.5.

I haven't been giving any nutes as i was under the impression the the FFOF soil had enough veg nutes for a month. I'm watering every 2-3 days.

The bagseed plant is the largest bushy one, the leaves on it are looking discolored from the outside in, not really sure whats up with this one, although it has been through alot. Maybe a calcium def?

The 4 purple power plants are having yellow, crunchy tips. I'm not sure if it's a Nitrogen def as all the leaf tips aren't yellow, not sure maybe heat stress? or maybe light burn, my 400w HPS was 18inches off plants for 3-4 days. Currently light is about 3ft off of plants. I'd like to get some opinions. I can take all the additional pics you need if you need side shots or whatever!

Thanks!

P.S. Before you say anything about the environment, this was unexpected as my hydrohut off-gassed all my previous attempts! Planning on getting a secret jardine ASAP


Bagseed Discoloration


New Purple Power 2-3 weeks

It doesn't really look that bad. Just keep doing what you have been doing. It might have gotten a little too much nutrients all at once with the foxfarm soil. That stuff is really rich. So, i wouldn't worry about it unless the new leaves that are coming in start getting brown at the tips or if all the other leaves start getting brown. That's nothing. By the way, you wouldn't want to see my plant after a month, but its hydro.

ya im sure your plant is further along, i believe these have been stunted by that temperature problem
