Black tips and spots on the leaves

GEESTGROWstarted grow question 5 hours ago

I'm having problems with the leaves. I estimate that the plant has about two or three weeks left to live, and I don't want to have issues now. Some tips are darkening, and spots are appearing on the leaves

Anytime leaf is curled up is trait of overheating, or plant is not cooling as fast as its heating, water is having problem uptaking, most likely from high ec your pot is suffering, the black tips are indicative of high salinity. Once it gets too high it messes with water uptake. Causing curling upward. Overfeeding. Lack of oxygen in rootzones. High ec. Solution: leech and dilute the medium with clean water and monitor the EC levels until they reach the desired range for your plants. 1.2 -1.6. Maybe a bit lower, then apply desired fert.

I had a similar problem, are you sure the cabin is not overheated? The leaves are curled up like claws. This is an action the plant takes to provide moisture and shade to its leaves. Small leaf tip burns are not a big problem. Follow the spreading situation, intervene if it progresses.

Deficiency issue/problem with leaves Any idea what problem I’m having with my plant/leaves? I’m guessing some type of deficiency because I’ve only fed once and it was a few weeks ago. (Check photos in most recent week). Any advice/ tips would be awesome, thanks!

She seems to be struggeling a bit because of the colder nights. Could this also be due to that? Looking forwards to your answer, dear question replier!
