ive got a purple urkle plant thats looking like it has a nitrogen deficiency. its yellowing in the leaves, and its growth has been stunted. its 1 week into flowering and im kinda worried about it. how can i get more nitrogen to her quickly? the root uptake isnt real good so i was thinking about foliar feeding, but ive never tried it before. im using the botanicare line of nutrients right now. is there something i can purchase that can give it a quick dose of nitrogen? thanks for any opinions
