Whats going on with my plants? Deficiency or bug signs. Pictures included

Plants are 7 weeks old. Flipped into flower about 3 days ago 12/12. Ph about 5.8 -6.2. Mostly coco/jiffy and some soil mixed. Temp runs about 73-77f day and 70-73f night. Humidity about 42-50 on average.

I found some gnatts or aphids notnsure which about 3 weeks ago. Used diatomatious earth layer on the soil and a hydrogen peroxide drench with my nutes (half strength) then the following with reg nutes and sprayed spinosad foilar twice three days apart. The following watering was a spinosad drench. The coloring on the tips started after the drench. The tips were turning browiah rust color. The twisting of leaves and chunks missing started when i noticed the bugs. But CAN GNATTS DONTHAT? OR DO I HAVE SOMETHING ELSE GOING ON? Please help me figure it out and all help is appriciated!! Also i dont know why it has whitiah spots poppoing up on the edged..

Also i sprayed them with neem oil two days ago

This showed up the day after I did a spinosad drench so the ppms must have been high. I may have put too much in bc i didnt give any nutes. I dont think im watering enough for the run off to get rid of past nute build up.

That's possible as well, make sure when you water you see a sufficient amount of runoff.

They won't always show sex in veg, many growers will take a clone from the plant earlier in veg and put it immediately into flower just to see the sex.

Ya i dont have the means to do that.. And def too late now. But thanks for the wisdom my dude. Appriciate it
