The leaves are wierd shaped, but growing fastHi everyone! Please tell me, is it a consequence of leaf scorch with light, or incorrect watering, or I was very in vain in the beginning added root booster? The big question is, is it worth waiting for a potential recovery?There's nothing like it at googleLeaves. Edges burnt

Any ideas what this could be?Out of all 6, she’s the only one acting up. Transplanted her last sunday. Started seeing this around Tuesday. I do believe I overwatered on accident but all of my other girls are healthy. I’ve done nothing different between themWeek 5

Spots on leavesI'm still dealing with some spots that seem like cal-mag lock-out/deficiency but my PH is at 6.2-6.5. I think the light was too powerful I moved it up from about 16" to 18". I hope to have a lux meter soon to confirm any light stress issue.
Still look like PH fluctuation?6y ago
