Early signs of Calcium deficiency?

Coughystarted grow question 6y ago

See a deficiency here? The whole leaf is very mildly spotty, like just a shade off... seems to be getting worse but very slowly. I had to filter the pics I took, were over exposed.

Leaf diagnosis required green love potion almost a full 5wks into flower and today I noticed some rusty spots on a few fan leaves as well as purpling at the tips. The only leaves affected so far are the one pictured and they are near the bottom of the main cola, is this anything to worry about?

Brown Spot Assistance, Please Noticing these brown spots on the leaves are getting worse. We started Fox Farm Tiger Bloom about two weeks ago and my thought would have been that would have helped. Would appreciate any insight into possible cause and level of concern. It’s flowering really well. Thanks!

My Tangie photoperiods small leaves are curling upwards around the edges. Anybody have a reason for this? It's the only one of the 4 exhibiting symptoms like this and only one of my autos of the 8 did the same thing. Is it too much or too little water? Not enough airflow?

Found something weird on my new leaves. Need an expert's opinion Found something weird on my leaves. I need an expert's opinion and insight. I don't know if it's natural to occur on newly developing leaves or if it's an issue that needs to be addressed. I'm thinking it might be natural but it seems weird to me.
