Hello all, the wife and i decided we'd give growing our tomato plants indoors this year and up till now i thought things were going great.

Our problem is they don't seem to be producing, just growing. And the PH has been coming up instead of going down.

The plant's are Burpee Beefsteak Organic Tomato plants. We have 12 plant's 24-36+inches tall. In a top drip recirculating system. They are at least 95+day's old. So i think they are mature enough. Since it was our first time we just went with the FLora Series. For this last batch of nutrients i didn't add the FloraGrow, but did add the Koolbloom. Cause i figured i was getting to much Nitrogen. I have also noticed that the leave's seem to be undercurling a little not to bad and were a tad dark on there green color. Another reason i dropped the Flora Grow. Temp's run around 60's at night and mid 70's at day. I feed them an hour on and an hour off. And i just swiched lighting back to 17hrs it had been 12hrs. Have alway's been confused with that part of the growing process.

The only thing that i can think of now that i haven't changed is the light bulbs. I thought i bought T12 bulbs but i noticed when i went back and looked they are T8's.

Any help would be appreciated.
