Garden problems

So for some background, I'm running a new nutrient line as well as on RO water now and in a new environment coming from tents before. I've had one harvest, currently on week 6 into the second one with this line. The first one had this problem really bad, I was out of town so wasn't able to try anything while my help watched it get worse lol. But this round I cut back the amount of nutrients a lot as well as lowered ppfd vs last round and thought I had solved it until week 3-4 of flower it started to develop, week 4-5 progressing fast. Seems to mostly develop the first few weeks of flower every time I have no issues before that. Of all the strains in the rooms both times, the z-face has the least amount of it happening.

Some information:
Medium: Coco perlite 70/30
Feed: 3 times per day cycle.
PH: 5.7-6.2
C02: 1000ppm
PPFD: 800-1000
Room temp: 77-88
Humidity: 60-75
Strains: Melted strawberries, wedding Pie, Sour Papaya, z-face.

I was thinking raise the PH to 6.0-6.3 for all of flower as I used to run a lot higher in flower in my tents averaging 6.2.

Appreciate any input as always.

For some reason it won't accept all of my images when adding attachments. Breaks them. So here is this with all of them:

I mean its not just pics of random leaves, I included a heap of information. Maybe stating what types of pictures or what other information you would like to have would be more beneficial to all parties. Thanks for the response.

Video was fine, you don't mention what kind of nutes you're using. What I see is the begining of a Potassium deficieny, the tricky part is what's causing it? Deficiency or lock-out? If the nutes you're using are synthetic, have you flushed to remove built up salts in the coco? If not, that's where I'd start. Pour water, three times the volume of the pot, through the media, then after it drains feed per manufacturers schedule. Add the calmag to water, wait 15 minutes, add the other nutes, wait 15 minutes and then PH to 5.8.

Using drip hydro, so synthetic yes.

Currently using on the week 6 plants:
1.2ml calmag
4ml A
6ml B
4ml Flex

I have flushed typically flush once a week, and the way its happened both rounds using these nutrients leads me to believe it's a ratio thing vs a salt build up thing but I'm not sure. I was also feeding at a very high frequency before once per hour for 4-6 seconds. Switched to 3 times per day 15-30 seconds each. I felt between the amount of watering and the lower ph could have been a factor. I'm just losing my mind trying to figure out where it's going wrong. Nothing worse then having beautiful healthy plants all the way through then the last few weeks health goes to crap.

The other room coming up on week 3 soon:

Its been on the new feed schedule of 3 times a night so if in a few weeks nothing starts to develop I'll know that was a factor.

Thanks!

Hey, Filthy Farmer.

Complete information about your fertilizer program would be helpful. What brand of fertilizers, PPM/EC of solution and runoff, average moisture content of your media, any changes you have made to the program, etc. :))
