Hello. I am on my first grow from bag seed. I started four and ended up with one female that survived. I am three weeks into flowering and she is growing nicely. My question concerns adding water. My plant is sucking up almost a gallon of water a day. I have been changing the water once a week and that was when I added my nutes. I would just add plain water when needed. But she is sucking up so much right now and the tips of the leaves have started browning quickly. I am guessing it is because of the lack of nutes in the added water. Is it a good idea to add my nutes in my spare water so that they are in there when I add the gallon a day or should I stick with just plain water? I appreciate any help.
