Good morning, I have a problem with my leaves (I posted photos so you can see). I've seen that it could be a phosphorus deficiency. But it could also be a calcium and magnesium issue. Could someone help me with this? What should I do? Should I add a PK 13-14?

If you want to know what's going on for sure instead of guessing then check your runoff ph and ec levels, high or low ph adjust. High or low ec then fix. Feed proper nutes for the growth cycle and things will improve. Cheers friend

hey, using modern LEDs, the plants need more phosphorus. I've seen that you're still giving the biogrow. stop giving it, dude, you have too much nitrogen and add 1ml/l of PK and you'll see how the black spots disappear and the leaves will turn a healthier (lighter) green.
