This is a 24k gold plant in dwc hydroponics. I was planning on changing it to flower light, 12/12 next week. Brown spots began showing up on my leaves. The tips of some leaves and looking a little yellow. Any tips or advice on what this could be and how to resolve my problems? Sent from my iPhone using Grasscity Forum
Looks like nute burn.............possible magnesium deficiency......and maybe even a bit of Nitrogen toxicity..........
