Hi ! Misschien wat teveel voedingsstoffen, maar hoe is de afloop? Het lijkt eerder dat ze niet goed meer worden opgenomen. Check dit en je ph waarde. Veel succes!🌱

Yellow leaf tips and edges Yellow leaf tips and margins… what do you think? Nute burn? Light stress? Cold stress? Will this eventually resolve if I leave it alone and let it work itself out? (Which is what I’m inclined to do) Should I flush my plants or try some other intervention?

Early growth sick plants - photoperiod Purpling stem, yellowing leaves, droopy leaves - I’m thinking nitrogen deficiency, but I’m not sure if I should add more nutrients or not to my current solution or if I should flush completely. PPM is at 850, and the PH is 6.3. What are your thoughts? Any GH nutrient schedules?

Yellow dots on the leaves Hi guys I need your opinion I noticed some yellow dots on some leaves of my plants and I wanted to know if it can be caused by too much light or too much nutrient Or maybe it's just normal and I'm just paranoid XD I circled the dots that I'm talking about Thanks you !
