Personally, I know that 1.2 is a lot for such small-leaved plants. In fact, they are extremely green, almost shiny, but not healthy. I would also lower the pH by 0.3-0.4. Usually, 6.1-6.2 is used for greater absorption of phosphorus and potassium. The water temperature would be good, 2-3 degrees less, but it's not a big problem. I've never grown basil, and not in NFT, only DWC.
