What the #@&% is wrong now?! See pics

Okay, getting frustrated here. I've been growing indoors for about 2 years now, and I seem to be getting worse at it. Or something. This is my latest batch... here's the stats:

-These pics were taken at 4 weeks of flowering to the day.
-The strain is White Widow.
-The planting mix is Pro Mix, doctored with 1/3 cup of Dolomite lime per 18 gallons, as well as 1/4 cup of Espoma Flower- Tone per gallon.
-The pH (taken from the runoff water and tested with a GH drop system) is 6.5.
-At the time these pics were taken, they were in this soil mixture for about 2 weeks.
-I have been treating with Spinosa for thrips, which I think may explain the crusty curling tips of the upper leaves, but not the wilty, yellowing with brown spots on the lower leaves.
-There are also fungus gnats, which I am going to get rid of following this harvest using Gnatrol in the moms.

Any help and advice anyone can offer would be much appreciated!!

Bumping it up... I need help please... thanks.

Yikes. I'm sorry I don't know enough about nute burn or why they're doing that. For the damn dirt fungi, I put a saucer of water with dish soap in the cab (also around my house for my plants if I get them) and dump 8-12 dead ones per dish a day. I also leave a new bag of dirt open for a day or two to watch for them before planting something good into the bug-ridden crap. How close are your lights? Curling up is an indication of too close.

Lights are about 1 to 1 1/2 feet away on a light mover- should be sufficient, or at least it has been in the past. That's the part that I'm thinking might be a reaction to the Spinosa- maybe I'll move the lights a little further away until I'm done treating them.

The fungus gnats (what do you call them? Dirt fungi? That's new to me) apparantly can be eradicated fully using Gnatrol, which is a beneficial bacteria that attacks the maggots in the soil, breaking the life cycle. I'll let you know how it works when I use it.

So you're thinking nute burn, eh? That's what I'm thinking- if this is the problem, anyone have any suggestions? I've only used organic nutes, so I'm not sure how effective flushing is going to be (non-water soluble and all)... I'm thinking I'll try and flush with Flora Kleen and see if it helps... anyone else have any suggestions?

Thanks again-

I have used Gnatrol and Gognats seems to work better....

Thanks for the info, I'll check it out.

Bumping it up one more time... can anyone help on my original question? Thanks all!

ive got a similar problem i dont think its nutes tho..i havent received much usefull help yet....altta jaber about everyother detail tho....let me kno if you get a def answer!...happy token!

its not bugs ,, its Nute Burn

it looks like nutrient burn to me too i would run plain tap water through them several times then not feed them for about a week that should help. nutrient burn can be a hard problem to fix during flowering. i noticed you said you were getting worse. sometimes after ppl have been doing this awhile ppl tend to fiddle with things to much. i have been growing for about 1.5yrs and have had a prepetual grow. i use fertilome 20-20-20 for veg and 9-59-8 for flowering the bud in my pic is using this method i follow direstions on the can. it seems like it is easy to want to do things to plants when nothing is the best thing that can be done. i think you will come out of your slump. just remember patience water light and air is all these plants need. forgot i also am a soil gardener the dirt i use is a house blend with no slow release in it. i hope this helps you if you do a flush you should see results in a week or a little longer 1.5weeks good luck

What are ur ppms of of solution going in and going out? when in doubt flush it out. Flush with 3 time normal amount to get good amount of runoff and test it. That will tell you what going on in the soil.

That Espoma Flower- Tone is Very strong stuff , when it kicks in it is HOT!
All of the above advice is what i would do , flush with 6.5 water and stop feeding.
the damage leafs will not recover , but all your new growth should be fine
