First grow, pics, advice needeed

This is my first grow from bagseed from bricked mids, they are 46 days old from sprout. I have a few concerns, first is the bug problem. I am using DE on the base of the plants, iron phosphate slug bate in surrounding area, neem oil once every 7-10 days, and this other bug spray that is A-something and D- something that the grow shop said was very effective for existing bug problems. Second is the brown looking shit where I FIMed... is that normal? I'm really hoping it isnt spider mites. All are in the same soil. I fertilized with 1tsp of 0-10-10 alaska organic and 1 tsp of 5-1-1 per gal and each got about 2/3 gal to all the plants 2 days ago.


I'd also appreciate some fast responses, as I am headed to teh grow shop in a couple hours, thanks.

Plant 1: The leaves were looking like that but not as bad on 3 plants a few days ago. The others got better but this one got progressively worse after the fert.







Plant 2:






Plant 3: FIMed 2 days ago








Plant 4, looks like a little burn, fimmed 2 days ago












Plants 5 (left) and 6 (right). 6 was FIMed 2 days ago

Browning at the FIM spot is normal. My plants turned black at my FIM spot after a day or so. As for the bug problem, just keep up with it. I sprinkled the powder all over the plant when I had a similar bug issue. It took a few days to show effect, but afterward it only suffered minor bug issues, which in high vegetation areas like yours, its pretty much unavoidable. Rain washes the powder off so no worries about it screwing up your plant.

any estimates on what type of yield i could expect considering i can keep the bugs at bay for the most part? I'm in NC
