Hey guys I've been around for a bit just reading. I have been growing for over a year now and have just experienced a new problem with this batch. I was growing in an open space in my basement but due to light leak issues had to build a cabinet. I'm running an air cooled 600w mh/hps. My problem is that some of my the leaves on my plants are underdeveloped. They lookl like they just stopped growing half way to their tips or someone took a pair of scissors and cut the tips off of the leaves. My cabinet usually stays around 80 degrees with about 40% humidity, oh and this is a dwc setup. Any feedback is appreciated.
