In the last week a few of the leaves on my plants are looking like the pic below. Any ideas? .. Been on miracle grow, then switched to 10-50-10 yesterday and noticed these leaves. Any ideas?

I think your leaves are burned, not by the sun, but by giving them too much fertilizer. Marijuana loves as much food as you can't give it but it has to be slowly introduced, gradual. It's hard for the plant to go from 20-20-20 to 10-50-10 in a week. You should probably give a 1/4 tablespoon and increase the strength every feeding.

looks to me like minor insect damage. i have similar spots on mine and have a few white flies buzzing about but nothing serious enough to bother with fixing...it's also similar to what spider mites leave behind but i don't think you can blame them for what you've got...looks like a plant/leaf sucking insect tho.

i wouldn't worry about it.

fert burn starts on the edges and works inward leaving brown, dead-dry crispy leaves...

the root's are burned from to much first wich fucks around with the whole plante the buds will be smaller and the leaves will be all fucked up like that try and replante them in some good dirt and firt but no where as rich as the souil you have them in peace man
