That happened to some tomatoe plants that were growing in a greenhouse the plastic was like a light filter and I decided to put them out in a bright sunny location, then the leaves started to fade. The tops of the plants had fresh green growth after a few days. Plants have to get use to the natural daylight uv rays and outdoor elements after being enclosed in a controlled enviroment, jut give it time to adapt to moving outdoors. About Ph, very important to check so plants uptake all nessesary nutes that they need only when Ph is at the proper levels. Start collecting rainwater to the water you plant's or go get reverse osmosis water for like 2 bucks for 5 gal at the those refill stations outside the super market's.
