If I’m not mistaken I believe then have a little more magnesium than they like a good plain ph watering 2-4 should do the job. OR they just received the food and need a little time for transformation and adaption

Leaf diagnosis: nutrient burn or deficiency (or both)?
he leaves with the burnt tips appear to be more prominent at the top of the canopy, only affecting new leaves. A handful of these leaves look a little twisted. Meanwhile, the yellowing leaves are more prominent in the middle of the plant, just below the canopy

What could it be?
I'm a relatively new grower and I don't have a diary setup yet. I know it's hard to diagnose a problem when there is no diary, sorry! They were good until they started to yellow. They are in their 5 to 6 weeks of flowering. Some are good some are yellow and I feed them the same.

What should I do from here?
I had some problems about a week ago. I investigated, and corrected at my best, but I am not sure what to do from here? Do they seem to get better? Should I do something different or just keep going as I am? - More pics and info in my diary

Dying leaves
I had some mild nute burn last week on a few plants. A few tips were burnt. Some lower leaves are turning yellow and dying. Is this still nute burn or something else?

Experiencing some deficiencies/light burn/heat stress. Says SSH likes hot/moist climate. Plants are planted in FFOF Soil, fed them 15oz of nutes yesterday. Using advanced nutrient systems, see above. Light is a SF1000 LED meant for a 2x2 tent. Would that burn them hanging at 20”?

She has yellowing and dying leaves issue for a while now. I was giving more nutes lately to combat the issue. Now burnt tips say it is to many nutes. So I decided yesterday that I should water with a bit of calmag before next feeding at beggining of the week.

Yellow and fragile leaves 2 week
Couple leaves yellowing and bit curved up. I suggest there can be the options: 1) magnesium deficiency; 2) nitrogen deficiency; 3) Light burn. For case it is magnesium deficiency I sprayed the leaves with magnesium sulfate (solution - 1g per 1 liter), but it won't help.

What’s most likely causing this?
What does this look like? Soil ph seems good and I’ve been giving them light feedings of nutrients. Any possibility it’s a symptom from being root bound? It’s just a few leaves on the bottom of the plants.

The leaves are wierd shaped, but growing fast
Hi everyone! Please tell me, is it a consequence of leaf scorch with light, or incorrect watering, or I was very in vain in the beginning added root booster? The big question is, is it worth waiting for a potential recovery?There's nothing like it at google
