Yellowing and Dryness...Tomato plant

Dry leaves & Yellow spots...oops!

The dry leaves seem to be anything from nutrients, heat, environment, how you look at them...`so I am not sure on that. The yellow honestly worries me a little more than the dryness.

I think my lamp is too close for one...I plan on lowering my plants later tonight, but I need some training help honestly. My tomato plant is huge, as I believe its indeterminate and I didn't pull suckers off as I should have haha. Oh well! I already have fruit so i'm going with it.

I'm running Flora Nutrients, and just switched to bloom. I had 1 night where I had to run clean water which I think is just fine, and then went to bloom nutrients straight away after that. The plant drooped a bit with the water only but perked back up with bloom nutrients and seem really healthy...just some dryness and yellowness. It stays ~85-90 in the closet but the water doesn't ever show signs of algae, so I don't think that's the case. Is there something I can do to try and cure the symptoms without buying hydro stuff? I don't have a shop nearby and a weeks wait may be detrimental, I don't know. Thanks for any and all help.

the yellowing could be caused by too much nutrients, and this could also be affecting the plants ability to intake water. The yellowing could also be because the plant is receiving less nitrogen now with the bloom nute's. I would be mixing in veg and bloom nutes together at 50/50 for the first week at least. also the temperature is a high, you should keep it closer to 70 - 78. the humidity too low could also cause the 'dryness', try misting the plants.
