4weeks3days into flower

Hi guys my white russians have been flowering now for 4weeks 3 days now on a 600w hps bulb and my pistols have been turning brown now and on the outer buds they are more brown than white.

They have suffered serious rust spots which i posted recently ago with pics attached

My question is should i just leave them in for a few more weeks till top buds are brown or shall i chop them off and leave the upper buds in

if what your talking about is mold, you dont wanna smoke that shit, and getting it off and away from the plant is prolly a good idea...

Hmmm i dont think id wana be smoking that at all
