1) Pictures are attached, both with lights on and off and taken minutes ago.
2) Growing indoors with seven other plants. 6 autos and two photo periods. All feminized
3)Using full line of Earth Juice with hygrozyme and hi-brix, watering schedule right now is feed one week, water the other basically. Orca Liquid Mycorhizzae and cal-mag
4) Fox Farm Ocean Forest w/ Earth and Grow probes
7) Using a 1200watt LED grow light, currently 24" from canopy and maintaining 74-80 at canopy level
8) Have two naturally-producing C02 bags in the tent, several fans, two exhausts and humidifier that keeps it about 65-70% RH and digital environmental controller
9) Soil PH is currently about 6.8-7
10) I have used Dutchmaster liquid light and saturator at a very weak mix at about week 1, but haven't since.


In this current grow, I have my two photoperiod plants in 5 gal pots and six autos in 2 gal. Last night, I noticed a browning spot on one of the autos (Northern Lights X Big Bud), but it was also at that moment that I noticed small bugs in my two large pots. I assumed all the pots were infested, so I did a root drench with two gallons across all eight with a mixture of GoGnats and SM90 (3ml per gallon) and then did a Foliar spray with sm90 on all plants last night. I went to check them this morning and while I'm not seeing any bug activity currently, I did notice that the browning on the plants got worse and spread to a couple other plants. I am about to get some diatomaceous earth and spread that on top, but seems some of the bugs are still hanging around in the soil a day or two after application of sm90.

They've mostly been getting water, think I've fed them once and watered 3-5 times and they're 3weeks old. This issue just appeared within the past couple days.

My question, does this damage look bug-related, SM90-related (it did get worse post-spray/drench) or does it actually look nutrient-related? Please helppp! Cheers in advance! Pictures are of the 3-4 autos that seem to be afflicted (also some very slight damage to my Berry Bomb photoperiod lady)

It does not look like bug damage to me. Looks more like a nutrient/PH problem to me.
I wish I could be more help but I suck at nailing down nute' def' or lockouts.
 
That is an odd problem, but I don't see any logical pattern to the damage that would indicate a feeding problem. These spots are random, and non existent on the new growth. The color is excellent and I see good transpiration.

I suspect it is something to do with the chemicals used to eradicate the bugs, and good job on that by the way... quick and decisive. I think that some of it may have burned little spots on the leaves where it lingered.

My advice here is much like my doctor would give to me... smoke a bowl, and call us if the new growth starts showing similar damage or if the problem below progresses.
