so I have been reading on this forum for awhile now and have found pretty much every piece of info I have needed, but this issue has me worrying a bit.

Ok so I've grown his plant from seed. i started back in the end of April. I have had it in 12/12 for 30 days. I've been watering a half gallon of water every 2 days and just started using some tiger bloom. I used about 2 tsp which was what was directed. I also had a pretty bad fungus gnat problem, but I have been using neem oil. there are only a few flyers here and there.

Grew w/ flourescents until about a week ago. Picked up a 400 watt hps.

Also, Ph is good.

I think the issue is either nute burn or the larvae are eating my roots, but I am not sure, and this is a crucial time for bud development.

Here are some pics. Any input would be awesome. thank you!

threw in a few bud pics too lol

When did you start seeing the problem? Could it have anything to do with switching to a HPS? If pH and nutes are good I can't think of anything else it could be.

The fungas gnats will die off when you quit over watering. Only water when the top 2" of soil is parched. Check out this watering and flushing tutorial

It also looks like you have phosphorous deficiency, but the bloom nutes should cure that. Just don't over do it with the nutes. It's best to start with half what it says on the bottle.

Is that powdery mildew on the leaves too? Less watering should lower the humidity

I don't believe it's powdery mildew. there is no white. Just yellow and brown.

I just had that same deficient Phosphorus problem along with an Mg deficiency. I added more "P" and carefully foliar fed with a half dose fert mix, and a half tsp. of epsom salts for a few days. Worked like a charm. All healthy now. Pretty sure it started with a PH problem, so I flushed once and adjusted first.

EDIT: IMO pic 4 looks like an Mg def.
