What’s up guys! I’m 6 weeks into my critical
Jack Herer auto grow and my lower leaves are starting to yellow. Plants are flowering looking nice, other leaves look great but the bottom ones are yellowing. I just started bloom nutes at 1/8-1/4 strength. Is this normal?

I’ve been giving it 1/8 strength every other water and the tips no matter what get a little burnt. 6 and a half weeks in is this normal? Should I lower strength? It’s already a small dose to begin with

Bud, I'm not seeing nute burn in those blurple pics. I feed the few autos I've run this year almost full strength feeds. Not suggesting it. Just saying i experimented with 4 autos this year and was using full strength Lucas formula at the end. Feed, water, water. Repeat.

Normal those leafs will die off the plants just relocating resources.

Here are some pics. Does it look like bad nute burn? I water 1/8th strength every other watering so about twice a week, which isn’t bad. And the leaves are getting a little more yellow. What do you think?

Veins remaining green and margins yellowing indicate a magnesium deficiency to me. I would introduce some epsoms salts to their diet. Two benefits, magnesium and sulphur.

ran a photo through buddy.kindbot.io which suggests magnesium because of the yellow striped leaves
try it on other photos to help narrow the diagnosis search
