It has been extremely hot her in Central Texas. Over 100 for 10 days, and the next 10 days.
I thought I had Nute burn, and flushed the 5 gallon fabric pot. Things seem to have gotten worse. The plant was transplanted to Fox Farm soil almost 15 weeks ago, and started flowering about 8 weeks. I have also been using the ILGM packaged nutes.
Looks.to be excess nitrogen. See how the leaves are dark green and waxy? I would back off feeding and just water a few times then feed. The heat above 100 isnt helping either.
They are in fabric containers, so they should drain enough. I had them on drip irrigation, since they are in a remote location, and I can only get up there every 4-5 days.
