This is a sign of calcium deficiency, but I see that your leaf looks pretty dark green so this could be the problem. If you add too much nutrients it can lock out other nutrients causing these issues. I suspect this is your problem. The other thing that could be causing this is too much pH fluctuation or your pH running out of range. In soil I shoot for a pH of 6.5 and in hydro I shoot for a pH of 6.0. So check your pH and if it is in range then I would back off the nutrients a little and it should stop the problem from spreading. Good luck!

Most likely Calcium or Ph related. But half a leaf does not a very good diagnoses make. Although it is clear and easy to see. Foliar feed Cal-mag to fix the leaves, or leave them they won't fix themselves. But make sure too add more cal-mag to the mix so that it doesn't spread. Or if you are fairly certain you have enough Calcium, Ph could be another culprit.

Yellow/brown leaves Noticed a brown/yellow colour starting to appear on my leaves. I don't think it's from the light being too close, so most likely too much/not enough nutrients. Any ideas?

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
