Just to be clear - do you supplement with the grow fert or do you use it by itself. Also, if the mylar is touching the water, is it harmful to me in terms of smoking the final product or will it just kill my plants?
dejayou30 Reviewed by dejayou30 on . Nitrogen Deficiency in Flower I am pretty sure I have a nitrogen deficiency. The bottom leaves are completely yellow. I am two weeks into flower and coincidentally I'm due for a res change tomorrow. Could this be why? My nutes are Botanicare Pure Blend Pro Fruit and Flower 2.5-2-5. Its only appearing in one or two plants as of right now. If its not just my plants signaling that its time for a res change, what's the best way to add nitrogen without hindering the flowering process? Rating: 5
