I looked at your feeding chart and I would say calmag. If in tap water you need to add calmag. Tap water has different things calcium and magnesium is one of the natural things water gets from traveling through ticks and stuff. Your plant ate more then likely all the calcium and magnesium. Check your Ppm in your water say it's at 175 straight out tap. Now add calmag till your ppm is about 250. Advanced Nutrients says to have a base of 350 ppm of calmag. I only go to about 250. I have went to 350 with clone and done fine but mine do way better about 250. I bought a filter that goes on end of my house it's amazing. It got my ppm in fifty's and low sixty's. Look into a base of Cal mg ,hope it helps. Happy Growing and blessings on all your CROPs.
