Leaves Yellowing Between Veins

Hi I'm having some trouble with my plants. My leaves have yellowing in between the veins mostly on the new growth. I have them under a 4 foot T5 fixture. The PH is 6.0 and i gave it dolomite lime recently. Still waiting for the PH to go up a little more before I treat it for a deficiency. The temp is at 71-72F, the humidity i can't seem to get up even with a humidifier. It stays from 35-40%. Do you know what could be wrong with these. I look forward to your replies.

I have to look into it a little more but I would have to guess that it is a nitrogen deficiency. A light sprinkling of blood meal should do it but be patient as blood meal takes a little time to get up and going. It works great though.

Thanks man. The only weird part is that the new growth is the part that is affected the most. As the leaves get bigger, the yellowing between the veins goes away a little bit but not all the way. Do you think it's ok to treat for both nitrogen and magnesium? Thanks again

Lime can take a month or more to break down and 'sweeten' the soil. Use ph up to raise it, this does look a ph issue.
