That is a calcium supplement issue normally. Especially when into flower the plant uses it all up and its stored in the leafs . Just add abit cal/mag to your feeding

Too much light or other deficiency Too much light or some other deficiency? I’ve been having some issues with yellowing leaves and some other issues with browning and wilting/curling which I thought was initially nutrient lock but what I noticed is all four plants were not stunted and continued to grow normally.

I flushed it because some leaves were showing some Nitrogen Toxicity. Run off was coming at 3000ppm and I fixed it to 1500. Now the older fan leaves are yellowing with some brown spots (check the last picture). It's a deficiency? Should I increase nutes? Thank you very much!
