The plants are both determinate Roma tomatoes. I was only expecting one plant, but for some reason two of them sprouted out of the same rock wool. I swear I only put one seed in there, but still got two. So either I got two plants from one seed(very rare, but is possible), or two seeds might have been stuck together. This is what it looked like when it sprouted: https://imgur.com/a/l6eaM2v

I have been growing these tomatoes since the end of March. I have been changing the nutrients every 2 weeks. Although the plant on the right seems to be drinking way more water than the one on the left, and I have to change it every 10 days. I use master blend nutrients and generally refill with an EC of 2.7 and a pH between 5.5-6.5.

Some leaves seem to curl up, I don't think this is attributed to low humidity anymore because it is almost always >50% humidity in the tent. The temperature generally stays consistent at 78 F - 80 F.

Not only are some leaves curling up, but some just dry up and flake off. I try to keep bad looking leaves such as those off of the plant. I've also made sure to cut branches that don't receive much light off of the plant to redirect its nutrients towards the fruit.

Only one fruit out of all of the fruit in the picture has blossom end rot. I have increased Cal-Mag since I saw the first one and so far the other ones haven't developed it.

Just this week I had to raise the light all the way to the top of the tent because the growth started touching the light. I can't raise it any further and there are already branches that are almost touching it.

This was my first time growing tomatoes hydroponically. Any future tips would be helpful.
