yellowing leaves + brown spots on flowering plants

hey guys, couple pics of my plants. they've been flowering since thanksgiving. These plants recieved massive amounts of heat stress between oct 29th and nov 1st, didnt think they were going to make it at all. Plants are in FFOF soil, with minimal amounts of earthworm castings mixed in. I've applied light doses of Foxfarm tiger bloom, about once a week, but I fear that i've burned the plants at this point. pics are of the larger plant, Warlock, with some close ups of leaves from both plants, a bud pic so you can see how far along in flowering they are, and a setup pic.

You've got thrips in your soil. use a pyrethrum insecticide as a soil drench and spray the surrounding area every week or 2. Thrips can jump far so make sure to spray everywere!

You might be overfeeding but i doubt it. Warlock is a good feeder and can withstand high temps so i wouldn't worry.

Just get those thrips taken care of otherwise they can multiply quickly. They like standing water for breeding so if you set a cup of water by each plant the thrips will travel to the cup when the soil gets too dry. Check the cups daily and pour down the toilet while flushing if you see little specs floating and jumping on top of the water. Its important to pour it out while you flush otherwise they will jump out of the toilet before you get a chance to flush it.

Good luck!

How can u tell it's thrips?

I will say that I've found small, white bugs (today actually), in the soil of my vegging clones, I havnt found it in the larger plants, but I can believe that they are in there. how did you know?

I have those brown spots too along the veins. Out of curiosity the spots are only on a few leaves? I've been removing the leaves thinking they were leaf spot or an infection of some sort but it keeps coming back.

I've also been removing the leaves, throughout the whole lifecycle. theres been quite a few that I've taken off, probably over 10-15 grams dried. I still havnt gotten to the roots of the problem.
