help identify whats wrong with my plant please!

hey guys so been about a week since transplant and so far so good. Although I have been having a issue with a couple things

1.) throughout most the week the plants have been discolored in some spots and is curling

2.) plant leaves (on big and small plants) are curling up

Here are some pics for examples. If you guys could tell me what you think j would appreciate it

i have been rotating between water/ feed every other day.. so water one day, skip a day, then feed, then skip a day, and so on......

looks like your ph is a little off 5.8 to 6.0 in coco is good.
and you need some calmag additive also some perlite would not hurt in what looks to be coco I run a 50/50 mix coco/perlite.
also a small clip on fan blowing over the tops of the plants would not hurt.

Also only water small baby’s like that when they need it "start to become dry"
give the roots time to search out the water and grow.

starving

Looks like nute burn to me....

I'm using 100% coco. And mills nutrients. I'm using my city tap water which is about 8.0 untouched and PH it to about 5.7-5.8

And I did just go in there and wiggle plants around a little bit and there is a small bug that's flying around I have noticed a couple times now. But only 1 single bug that I see
