Burning from over feeding. Nothing to do with calcium. 18/6 is best for cannabis, they NEED sleep.

Yellow stripes have appeared on the new leaves and brown spots on the old ones. But the plant doesn't look sick overall (age 3 weeks).

Black tips and spots on the leaves
I'm having problems with the leaves. I estimate that the plant has about two or three weeks left to live, and I don't want to have issues now. Some tips are darkening, and spots are appearing on the leaves

Can someone tell me what is this? I think the reason is that my nutrients are not balanced but I have no clue what deficiency this is, It could be so much easier to know the reason for this if I know what this is. pH pretty stable 5.8 Ec 1.5. Thanks!

Leaves browning in multiple spots Lower leaves yellowing but have green veins.
One plants leaves are browning in multiple locations. I attempted to diagnose the problem with runoff tests. pH was 6.5 and TDS was around 900ppm, which was expected since they received nutes that day. Despite not spreading to other nearby plants, could it be leaf septoria?

So, my girl now is 11 days old, while i was looking at here i noticed that the tips of the second pair of true leaves is soightly yellow/brownish colored, im worried for my plant. Could it be a wind burn ? I have a ventilator in my tent which was blowing at here. I moved it now.

Flush or what to do ?
Advice please. I watered yesterday but the stains on the leaves are getting worse. Now I don't know if it is deficiency of cal n mag due to nutritient lock out which might be due to ph being off as I have 5 reders and all of them show a different thing. 🤦♀️...or it is it rust?
