cal mag issue or in that line??

I have found that those types of ph meters are terrible and I do not use mine for that reason.
You should be trying to drift through the ph range - not overcompensate and then back again.
Looks like thrip damage to me.

Well while you're waiting for the dr and the las. I'll take a stab at my woefully inadequate opinion. Mites and/or PH.

have you checked thoroughly for pests?

so yesterday i noticed spots that are small on some of the leafs of a few plants. now i don't over water them at all, or over nut them. I feed every other water, but i changed today and just gave it a water. My ph keeps going up to 7.5-8, i can only bring down to about a 7 ph, lowest i placed my ph at is 5 and that was today and the soils showing a ph of 7ish now. if i check later they might be back at 7.5 ish. should i lower the ph down to 4? attached is a few pics i took yesterday. I am more so think cal-mag needs to be added as i haven't added in this week.

tap water sit for 3-4 days in 5 gal water cont.
coco/original roots 65/45 mix
AN line
no ppm meter but meter in pic waiting on new meters to arrive.
hand water, 2-3 days rough but i monitor through out day and if need i feed or water
feed water feed schedule
2 t5 8 bulb 4 foot lights and a 4 bulb 4 foot light.
6x8x7 room
temps 77-81
humidity 40%-55%
ventilation in and out
fans moving leafs with light movment with small random burst of a little bit more from intake.

ph i cant seem to keep under 7.25 at soil so i wanted to know if i should bring water ph to like 4 since 5 is pushing 7 or 7.5
also if cal-mag etc is cause of bumps

forgot to add lights are 36-42" from tops of plant.
buckets are either 7gal air pots or 5 gal for the smaller ones.

found a bug on under leave!!! white with black lines ball like bug
