Day 20 Flower. Leaves curling

Mekster
Meksterstarted grow question 2y ago
Leaves 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?
