What have I done? :(
This is a red currant cherry tomato, started Jan. 12th. He gets the same as all the other seedlings which are doing fantastic, all very healthy happy looking. I used Jiffy starting mix, under grow light for 12-14 hours a day, transplanted him up to his own container a few weeks ago, and all seedlings get bottom watered every 4-5 days as needed. I have 2 other cherry toms, same variety, and 1 is like this but not as bad and the other is very happy and healthy. Any ideas on what I've managed to do to the poor thing?
