We ar just listing potential future issues. Plain water will fix the burning, water out over night will fix the ph rise. Raising lamps will stop burning too. (It's prolly drying up humidity close to plant) To add to the water bottle idea, if your temps are still an issue once you've added nutes to res you could look into making nute cubes. (Take nute solution, pour in an old ice cube tray and freeze. Add a couple to res, as needed)
Alright great. That nute cube idea sounds great. Right now ill do plain ph'd water until 3rd leaf set. Gonna do the water bottle thing tonight.
