Water on leaves. In one picture leaves are soaked. Light is magnified by water drops and then cools leaves in spots it sits.

It could be from nutrients touching the leaves when fed.

Look like nutrients have spilled on your leaves, causing a burn.

Please can someone take a look at my Gelato #33? She has some dark brown spots on the under leaves and the upper leaves look very dry. :/ I did some "fin" cropping and looks like it didnt went well. It mutated a little bit? It is my first time.

Yellow leaves - moby dick
The olders leaves started to die and to turn this yellow-brown color. I thought it could be the temperature (I am about to receive my temperature hydrometer to measure that), or over/less watering, or nutrients. The plant looked great a week before.

Brown spots, PH in run-off is in the high end (6.5~)
I see some brown spots on my leaves. I thought it was Calcium Deficiency caused by too low PH so I gave them PH 6.5~ with 30% run-off, and run-off shows at least the same PH so I think it is not too low PH, could it be caused by something else? Maybe too high PH or light-stress?
