Is this the start of a nitrogen toxicity?
Mr_Weeds_Autosanswered grow question 3 years ago
Dark green, shiny leaves are a sure sign of nitrogen toxicity, the solution is to reduce the nitrogen your plant is getting. If you are feeding extra nutrients, cut down that amount. If you are in the flowering/budding stage, make sure you’re using a formula that’s specifically meant for flowering, or else it could have too much nitrogen. If you are not feeding extra nutrients, you may have “hot” soil that has been giving your plants extra nutrients. In that case, flush your plants with filtered, pH’ed water to help clear out the extra nitrogen.

What is causing PK deficiency signs on mid leaves? Too little Calcium causing lockout??Hey everyone, in mid and late flowering with my autos, all experiencing similar problems and I’m inclined to believe it could be due to a lack of Calcium? Could a Ca deficient plant cause these symptoms which resemble a PK deficiency?? I’m 100% adding enough bloomWeek 11

Deep Ridges in leavesI have a whole strain (3 plants) exhibiting a general lack of vertical growth; but also deep veins and ridges causing eveb more malformed leaves. Same setup as my other 3 plants of another strain that are thriving.
Looks like pH issue? Maybe this strain needs lower?
