Probably irrigation residues? Observe the evolution of these spots carefully every day and check the sheet from behind. Have preventives like diatomaceous earth or potassium soap on hand. Regards!

Praying leaves The leaves are stretching up (praying leaves as I understand). It's just 1 day after topping and I would expect some stress, is this a good or bad sign? I fear I might have topped them a bit too early.

Curling new growth All of my new growth is curling a little bit. I dont think it's N toxicity, but it's also probably not heat because all of them look like this. Is it N toxicity or something else? Thankss

Seedling issue Hey guys my seedling got a little pale between the veins and started to get rusty on edges of leaves. I'm sure its due to unfavourable environment as it did get a little dry and humidity wasn't as high as it should have been. Looking for thoughts on whats up?

More rusty spots See this now on more and more leaves. Only upper fan leaves that get good light exposure seem to be affected from this and also the clawing. Have backed off the nutes completely for now and will add ground egg shells to the water in the hope its a Ca deficiency.

Rusty Leaves 3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera. I also have slight "clawing" on many of the upper leaves. Mg/Ca lockout because of nitrogen toxicity possible? Doesn´t seem to be fungi, as there are no spores to rub off.
