Browning of plant 1 lower leaves
Medi_K8started grow question 4 years ago
Guidance please, On my 1st plant it looks like it has a pH issue however my other plants don't have any signs of a problem. I don't have a pH meter but have test strips and I have not seem an issue with my water. Is the browning on some of the lower fan leaves normal?

Not sure it would be a ph issue, that usually effects the entire plant. Could be from adding cal/mg everytime you water, if that is what you are doing. Cal/mg once every week or 2 should be enough in soil grows. Just my 2 cents. Cheers

I would say its a ph thing. I would water in with correct ph and collect a sample of the run off and compare the 2 ph readings. If its way out on the run off you might need to give the plants a mini flush to get your ph back in scale.

Dark green leaves in meringueIs my girl telling me that the flowering fertilizer is too nitrogen loaded? I´m using top bloom from top crop, feeding at 1.4-1.6 Ec, and since last week I started to follow the feed-water-water schedule. The NPK of this fertilizer is 4-8-8. Should I adjust the input EC?5 years ago

Leaf damage/discolourationThe Skunk has been getting a lot of leaf issues. I have been trying to stay on top of picking them off as they appear in case it's rust or similar and can spread. It almost looks like cal mag deficiency, but I'm feeding cal mag each feed. This is the only one effected out of four

Why are there soon many brown spots all of a sudden in WK 7?I'm entering Wk 7 and the same lady is hurting again. She's been feeding heavy for last few weeks and doing great. So, I gave a light water/microbes dose w/can and Epson. Now I think its potassium or something else entirely... Brown spotting, yellow, crispy? Thoughts?5 years ago
