Too late for another trimming ?Show I do another trimming ? Most of the big upper leaves started having trychromes at their base so I am not sure if I should trim again at this stage. Currently in the 7/8th week. I already trimmed twice during vegetation and beggining of flowering.

Droopy Leave Any reason to be worried? I have 7 plants going, 5 on the same feed. Only 2 plants are doing this but they are on different feeds. One has been mostly water and the other has been on the same feed as the rest but they are all fine.

Dark leaves in DWC Hey guys, this NL auto is very dark compared with the other plants. Also had some spots on the leaves, but I did a Res change and defoliation of sick, bud site blocking leaves. Could it be a Cal-Mag deficiency? I was thinking nitrogen toxicity but no clawing of leaves.

I just got my meters in today. Soil pH is reading 7.5-8.0. I wasn't testing the pH of my water until now, reservoir read 8.3, applied pH down to get it to 6.7 and a ppm of 120. The ppm of the runoff for #5 was reading 1500, i flushed it down to 900. Are they locked out of nutes?

Leaf issues. Lockout? Need to Flush??Leaf issues started showing up in 2 of 3 plants, progressing fast. Soil runoff tests have been v. high (2000ppm+) so we're assuming it's a lockout issue. We watered 1 day ago, with 200ppm solution so pots are still very wet. Better to let them dry out a bit or flush right away?

Largest plant's bucket got empty on accident; Filled a 15gallon reservoir of full strength nutes and pumped the solution into the bucket as always. Next day my largest plant is dying and the other two are fine, looks like lockout. Flushed for a day and then added nutes, nothing..

Few leaves of my plants are getting these pattern with dots. I optimistically hope that it is just part of the aging of the leaves. Other leaves became yellow and fell also (maybe worth to mention). Is it normal? Thanks

Weird new leaves One of the two leaves from the newest growth came out curled and crisp. The other leaves seem a bit canoed as well. Any ideas on what is causing this and how to solve? It’s been outside with supplemental lights at night. Too much heat, water, etc? Please help.

Why suddenly curly leaves ?My S.A.D have not looked good for a few days, the leaves are curling up and some of the leaves are turning purple / red. Is that because of the cold? Last week it was very cold and rainy, between 6 and 13 degrees. Over-fertilization is impossible, I have only fertilized minimally
