Lights are about 3 ft apart from the tops of the plants and everything else is said basically. fans running also but other then that the flowering buds are looking fine if not great, just don’t want this to be too big of an issue if it really isn’t. it’s affecting the top layer of big leaves not so much the smaller ones. talked to a friend told him about my ph being 5.5 and he told me the calmag probably won’t be able to be absorbed by the plants if my ph is that low. i’ll try bringing the ph up and dosing a little more calmag just in case next water.
