PPFD Management -- Am I doing this right? :) (See fan leaf photos for curling)TS1000 (150W x 2), set to 75% at 12-14". "Photone" app (yes, not as good as a PAR reader) reads 580-700 PPFD, so I sense these girls aren't getting as much light as they could. I've read that pushing 900 PPFD is desired (CO2 bags);fan leaves curled. How should I think about this?

Why have the leaves on my plant turned pale and crispy?4 weeks into veg with auto and all of the leaves (including new growth) have turned very pale and dry, starting at the tips and receding rapidly.
I’ve used the same two part nutrient solution in the same quantities as I did with the previous same auto, so Disease maybe?

Day 20 Flower. Leaves curlingLeaves curled over 12 hour light cycle. Ph 6.0. Ppm 950.
I have been battling ph drop for a week. Lowered Ppm to 900 from 1100. Seems to have stabilized the ph and now the leaves are doing this.
I’m looking to do the day 21 strip of most leaves tomorrow. Should I be concerned?

Yellowing between veins on 3 of 4 plants, and curled tips - 27-29C in tent - Just heat/light stress or something more?Only on 3 out of 4 of my girls, see 1 pic of sad girl and 1 pic of happy girl. Does it look like heat/light stress to you or something more?
I was running my LED 45 cm below the lights dimmed to provide 20-30k lux at plant level. Just now raised to 65cm, lux 20k.

Kolas folding upwards?Some of the tops of some colas are stretching up and not flat to allow the pistils to form correctly. almost looks as though they are stressed - I have had similar things happen with other tents and had to remove the plants in the end. How can I stop this?
