Purple is OK if your growing grapes, right?

But I’m not, their supposed to be tomatoes, at least that’s what the seed packs said.
I am hoping someone my have a solution to my problem. This is the first time I have tried to germinate seed (tomato and hot and bell pepper) and have enjoyed some reasonable success. The seeds popped under coffee filters and were subsequently transferred to cells. In the cells for a couple weeks and potted up to 4 ½” pots. All is good… Three, four weeks pass, and now I am faced with wilting sickly plants. This is occurring only with the tomatoes, the others are growing fine. They were really healthy until a couple days ago, or maybe I am just paying more attention now. They are under 4-four foot 6500k shop lights, just inches from the bulbs. They were taken out of the cells (jiffy seed starting mix) and put into pots containing MG Organic potting mix (link attached). The leaves are pale green and curling, purple tint underneath. I the one photo, the super deep purple is caused by the flash, it is not really that purple. I read in a previous post a couple days ago some purple is normal but this seems excessive. I have been misting once a week with 1% hydrogen peroxide. They get pretty wet when misted. Any ideas? Thanks for any help you can give.
