Looks like a bit of nutrient burn. If the new growth looks ok don't pay it no mind unless it looks to be spreading. 🤘😤

Hello, From my little experience, i think it's due to an overuse of nutrients. You just have to adjust using plain water or giving less nutrients. Good luck 👌🏾

Yellowing, curling tips?
I'm in the middle of week seven and noticing significant yellowing, curling tips, especially on the top colas. Is this cause for concern and what could be causing? Feeding low-dose (1/4-1/2 tspn/gal) of dyna-gro bloom and the plant is growing in MG soil. I know, rookie mistake

Plant getting lighter — deficiency or excess?
Plant getting lighter overall. Thought it was N deficiency. Since N is mobile, expect older leaves to fade first. But its more the top/whole plant. Using Floragard Grow Mix w/ Greenhouse Feeding Bio Grow (1/3 dose due to pre-fertilized soil). Bloom fertilizer was added yesterday.

Why are my leaves getting brown yellow?
My leaves are getting brown/yellow, I saw online that it's a bad sign but I don't understand if it's under watering, overfeeding, underfeeding, light burn ecc? Thank you so much for the help first time grower.

Calcium deficiency?
I'm not so sure if it's calcium deficiency, what do you think? Watering 100ml of water minimum. Using 1ml calmag/per 1L(and other nutrients like N,P,K)..soil comes nutrient free. Should I water her more and add more calmag or is this a different deficiency?

Help with burned leaf tips
The tips of some of the leaves have begun to dry, curl, and look to be dying (see pics). I think it's some sort of nutrient burn, but I'm unsure. I water every other day w/ a solution of Miracle-Gro 24-8-16 at 50% recommended concentration. Used distilled H2O last 2 waterings.
