If its just the lower leaves it may be from getting them wet when watering.

Yellowing leaves. Zinc/Nitrogen deficiency?
My plant has slight yellowing on the leaves and discoloration and I don't know the exact cause, from research to me it looks like zinc or nitrogen deficiency? I don't think it's too close to my light (last picture). Can anyone help?

Light burn
I've got what I think is light burn. I can't dim or raise my LED lights (300w), but I'm currently running them 24/0. Would switching to 18/6 help? Or would it help to take the burned plant and have it out in natural light during the day? I'm growing autos and they're flowering.

Should I trim off the damaged leaves?
Should I trim off the bad/damaged leaves or leave them on? I'm not sure if it will help or stunt the growth even more(I don't know if that possible at this point but still). Do they even have a function after they got damaged the way they have? Please check my diary for pics

I need advice on what to do with this plant. I flushed her a bit and I think nutrient burining is not showing on new growth, what ppm should i feed her?
I watered only last week and mesaured runoff ppm and ph. Water was 350 ppm and 6 ph and runooff was 700ppm and 6.7 ph. Before when i fed her with 850 ppm runoff was 1500 ppm. I would continue to water only but there was a lot of yellow and pale leaves so gave her light dosage.

Yellow spots on leaves
Hi Growers! First grow here and I'm concerned about new yellow spots on my lower fan leaves (one tip is dark too). Soil is Atami Kilomix, heavily fertilized. 2 days ago only one leave was affected. What can it be? Mg def? N def? P def? N tox? Too less water (100ml every 2-3days)?
