Hello guys,

This is my first grow, I noticed one of my autos (blue dream) getting these spots on the older leaves:

I used the same liquid batch for all of my plants (flora trio), and this is the only one affected.

I did noticed I sprinkled some of my mix when watering this plant, instead of just fertigating the coco coir, so maybe this is residual dryed up nutrients? Since its only affecting the older leaves.

pH usually 5.5 - 6.5
Temps around 22ºC, 65% RH

Anyone seen this before?

Thanks in advance.

Clawed leaves, seems like something else. Possibly heat damage or some type of bug?
