Day 20 Flower. Leaves curling

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?

Leaves Turning Yellow - RQS Watermelon Auto Hi GrowCommunity! I am currently growing a RQS Watermelon Auto. The plant is in week six and started flowering two weeks back. I did some LST which the plant handled quite well. I am seeing leaves turning yellow starting from the inside. Is it missing nitrogen? Thx in advance..

I seem to have some yellowing on fresh growth starting to occur. I'm not too sure how to prevent it. I have started to do some LST and find it to be successful and a lot of fresh sites have appeared and wonder if this could inhibit it by stressing the plant?

leaf spots and curl I have a few leaves with some spots and a few that have a side that curls. What do you guys think? Right now I'm just using Fox Farms Ocean Forest soil and water - I'm planning on adding nutrients this week. Will that solve these issues?
