HELP!!...Shallow Rooting??

Why...All the sudden my plants aren't rooting very deep. Poor veg. leaf growth and speratic leaf (spotting) distortion. Flowering small sparse nugget buds. Hotter conditions maybe? Good organic medium. Flowering under 400 hps with good ventilation, temp average about 80-85 sometimes 90. From all signs, it has been suggested that I have a pH problem or nute. burn except that I'm using the exact same organic medium I was three months ago (for over 6 months) with fantastic deep rooting and vegetation. Flush and Adjust nutrient!! I'm trying to stay with an organic medium, avoiding supplements. Adjust & Test?...That is the real trick! . Anyone have any ideas why???

Don't double post. Your question is being answered in the other thread.

Sorry Stinky. I reposted here because I wanted the "Organic" opinion. Furthermore, except your opinion, my question was NOT being answered. By the way, who made you Cannabis.com’s posting cop?

Fine, be like that. I just get really annoyed answering stuff and then discovering that I've already spent 20 minutes answering the same question elsewhere.
