I started tomatoes from seed for the first time this year getting three varieties, Moreton, KC146 and Ramapo from Rutgers. I did the mini greenhouse with heat pad and fluorescent lights. All went well. I "thought' I did the correct hardening off, placing in the sun gradually and then in a shaded greenhouse. Finally last week, I set some in the ground. I am noticing just a bit of white shading on some of the leaves and I am guessing it's sunburn. Will these plants overcome that and survive? I still have some backup plants in the little greenhouse. Thank you for any advice.
