Burning from over feeding. Nothing to do with calcium. 18/6 is best for cannabis, they NEED sleep.

Slow growth yellow leaf edges what to do?
Plant growing slowly (but still growing) with weak growth tips and yellow edges on leaves with interveinal chlorosis. Looks like overwatering / magnesium deficiency to me. I use a weighing scale to know when to water, but started the plant in 25L pot so this might have caused it.

Brown spots with slight yellowing
Hello gromies. I'm seeing some slight yellowing and brown spots on my fan leaves. I've been bottom feeding so maybe it's a lock out issue with calmag. I flushed with tap to get some run off. Any suggestions?

Yellow/Brown Crispy Lower Leaves
Why are my lower leaves turning yellow/brown and crisping up? Is this a nutrient deficiency, the top leaves appear to be good still, but it looks like it's slowly making its way up the plant.

Yellowing...Deficiency or leaf septoria?
The leaves on the plant are beginning to go light green. Then I noticed this leaf with an unusual spots on it. I’ve been responsible with the nutrients. Hopefully this leaf isn’t suffering. I’ve moved the lights up a few inches to be safe.

Should I harvest early? Light stress, leaves browned and dried out, buds are all amber pistils
So this plant has been suffering from light stress for the past two weeks or so. I have removed all the dry and brown leaves. The buds still seem fine-ish. Should I just give her the chop early and save what I can? She's been flowering for some 6 weeks.

Yellowing Too Fast Or Natural?
I'm roughly 2-3 weeks into flower. Over the last week, I've noticed more yellow leaves than normal. Majority are bigger, older fan leaves but some are moving up the plants. New growths are a nice green and buds look healthy. Am I under feeding or overreacting?
