I'm attempting to grow an F2 [Solanum pennellii x domestic tomato] hybrid this winter inside. It is huge. The plant is doing well under some LED lights. The flowers awhile back seemed to take with the hand pollinating and a few set fruits. But some flowers turned yellow and fell off and now even the small fruit ones turned yellow and fell off. I think i'm lacking some sort of nutrient? I tried watering with some flower and fruit hydroponic fertilizer. But didn't seem to help. Maybe i should do that again now that it is finally flowering again.
