She’s fine, let her dry out a bit! Also add some Magnesium sulphate to straighten her out! Cal mag her up! Mainly Magnesium though!

Theirs plenty of nitrogen though, see how the leaves are slightly turning? This is a sign of too much Nitrates/nitrogen!

Why have the leaves on my plant turned pale and crispy?
4 weeks into veg with auto and all of the leaves (including new growth) have turned very pale and dry, starting at the tips and receding rapidly. I’ve used the same two part nutrient solution in the same quantities as I did with the previous same auto, so Disease maybe?

Leaves up?
Hey Guys 👍🏻 Quick question, I have my light (HPS - 250w) 40 cm above the plants - should I get the light lower? One of my babies has the leaves going up. I guess she is enjoying the light but I have doubts regarding the light distance.

Just to confirm, this looks like nute burn, doesn't it?
Burnt edges, tips curled up, canoeing. I've been having trouble balancing airflow and heat in such a small tent, and as a result the tent is on average about 28 degrees celcius daytime and the plants still get a lot of wind. Looking for whatever advice you can give! :)

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.

Brown spots and yellow tips in flower, started around wk 8-9. Thanks!
My 10wk old Auto Trainwreck started showing brown spots and yellow tips @ wk 8-9 but even after up'ing Calmag to each water wk 8 (1tsp/gal) it's everywhere now. It's been 75-50% the whole time- deficiency in late flower? Again big THX to the community - for more than just this.
