Are they getting enough food at the correct PH?It could be Calcium which is the most common but it also looks like Iron which is less common.Ph shouldn't be so much of an issue if that's soil unless its way out.Let you water stand for a couple of days to let chemicals evaporate and keep the soil microbes healthy.

Cal-Mag and N Deficiency in Flower? Thanks!I'm guessing the yellowing and brown spots (in Wk 8 pics) are related to Cal/Mag and maybe a lack of N? Would love some advice from someone who's seen this before Thanks! I'm seeing this in all my grows to some degree- using FF trio and FFOF but not for much longer

CalMag or something else?Discolored leaves at the bottom of a 3 week young auto flower, full feeding schedule in diary. Was thinking Cal-mag deficiency, but after 4 days of running 2mL/L Cal-mag supplements it's still getting worse. Could it be lack of phosphor, and will BioBizz FishMix/Grow be enough?
