Too little calcium in early flower?I’m in the early weeks of flower and am seeing this happening. I thought it was due to an attempt at foliar feeding, but those initial problem leaves have been trimmed.
Is this a calcium deficiency, and if so, how can I address it?

Super thin leafs at the TopThe leaves at the top are super thin, different to the others, the leaves are also darker green, I think it has some kind of problem! It looks like I overwatered it because the leaves are drooping, but that's not the case! Can anyone tell me what the problem could be?Week 6

White spots on leaves?Does anyone know why some of my leaves are getting white spots? It doesn’t seem to be affecting growth, and it doesn’t look like any white mold pictures I’ve seen. I’m thinking it’s hard water but I would like second opinions/thoughts!Week 4
