So a few weeks ago I ran out of bloom nute which was my only source of nitrogen. I have been using straight big bloom nutes since then. Could a nitrogen deficiency cause my plants to stop taking up water? because they got really yellow over the weekend and since have stopped taking up water. Oh, last week I also started using molasses, but my first thought was that they didn't like it or something so I emptied the res and didn't put any more in. I have these 6 plants under a 400 watt HPS and they are about 7-8 weeks into flowering. thnx.
