Not Nutrient Burn
Well I'm stumped...ppm 600, pH 5.9...it certainly looks like nutrient burn but it can't be, tips yellow then darken and curl and get crispy. 3 days between pics in question and in diary. My only guess is that I upgraded from knockoff 100W LED to Mars Hydro 150W. Any ideas?

Wilting leaves and copper spots? Save Me!
These copper spots started appearing around 2021-01-28, and the wilting leaves started 2021-01-29. The newest additions to the environment were the much stronger MarsHydro 300w light. I've had to water more often because it dries out pretty quick with the rampant heat. what next?

When to start using Cal Mag?
Tomorrow my Bruce Banner plants will be 2 weeks old. One plant is showing some yellow on the left side of one leaf. No yellow on any leaf tips and no claws. I believe I may have been under watering. My question is should I/can I start using Cal Mag or should I wait longer?

First time grower. Looking for suggestions.
Should I be worried about the slight yellow on the edges of the leafs? They don't looks very healthy. How often and how much should I water during this stage?

help! my plant is turning pale. the green color is losing.
the green color is losing. some leaves burn from the tip to the stem of the leaf. Excess fertilizers (because I fertilized the soil) or deficiencies due to few nutrients? I also thought that it can burn with nearby lights, but the ones that burn are far away
