1st try. Would love feedback and suggestions

I don’t have an ac or dehumidifier so I don’t have the best environment. And it’s been pretty hot outside. First time trying hydroponics so any feed back and suggestions would be awesome I’m trying to learn .
Day 21 flower . I feed them the full line up from advanced nutrients and elite 91 30ml of base and 15 ml for the additives in 4 gallons the ph 6.5-6.7 I was watering them everyday through my irrigation system but lately I’ve just started hand watering them when they dry out every other day. The temps in the day are 81-85 and at night 79-81 the humidity 50-60. I defoilated and lollipoped a couple times early in flower at day 7 and day 19. I don’t have anything to measure ppm and ec . I dont know much about ppm ec and vpd. Also not sure how far the led is supposed to be from the canopy. I got these clones in bad shape and from someone I don’t know so genetics can’t be verified.

Looks pretty good. Tiny bit of nute burn on leaf tips. I'd back off like 25% on nute strength. Was the pic you posted on Friday from the same grow? It looks like different plant structure.

I highly recommend you get tools to measure ppm or EC, and pH.

I've never grown in rockwool, but I'm pretty sure they need watered more frequently than every other day.

Good luck! Peace

Yeah it’s from the same grow . The pic I posted on Friday only one branch looked like that in the whole garden. I was watering everyday but I seen something how dry backs are important and how you don’t want the blocked to be soaked the whole time. That’s why jungle boys feeds them micro doses several times a day to keep them at the right moisture content . Maybe I’m feeding them more then other people and the blocks are staying saturated longer or my roots aren’t developed enough ? Or my vpd being off could effect the rate it up takes nutes ?

VPD will certainly affect the rate of transpiration and nutrient uptake. I don't know about moisture in rockwool. I'm pretty sure you can find some useful info in the hydroponics threads.

Is this still the same nute burn problem or something else? Should I defoilate the effected leaves ? Or just leave them day 24 of flower

The only strain with it looking like this is the 5 OGs I have The other ones just slight burn at tip

Check thoroughly for any bug pests under the leaves, just to rule that out. Otherwise, it's related to the nutes. Even if you improve the nutrient situation, the already damaged leaves will not improve. The leaves in the picture don't look so damaged that they've lost their usefulness to the plant. I would only trim off leaves that are more damaged.
