Purple Lemonade Auto - First Grow

Day 8 (5/17) ‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎- Started adding Cal-Mag Plus. ‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎- Bought a pH tester. It revealed that my pH in tap water was too high at 7.0 and too low in the RO water at 5.3. ‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎- Added ~600ml to the 3 gallon pot. ‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎- Raised the 1 gallon pot so that the canopy levels of the two plants were even. Day 11 (5/20) ‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎- Added ~600ml to both pots ‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎- Topped both plants Day 13 (5/22) ‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎- Started LST on plant in 1 gallon pot Day 14 (5/23) ‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎- Added ~1.2l (6.3 pH) to the 3 gallon fabric pot. This was likely too much but I lost track of how much I was pouring ‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎- Added ~750ml (6.3 pH) to the 1 gallon pot ‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎- Noticing some significant curling (up and down) to leaves on both plants. My best guess is heat and/or light burn ‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎‏‏‎ ‎- The leaves also look dark green which is a sign of nitrogen toxicity but it may appear this way due to the camera's color adjustment
