Pale Droopy Leaves, with a few rust spots... pictures inside - opinions greatly app.

Here are three pictures... these blackberries have me a bit concerned. Growth has been a bit stunted, and the top leaves are just pale and not very strong looking. I'm thinking something funky is going on here. I was thinking pH fluctuation at first, though to be honest it doesn't fully look like that. Calebrated my pH stick, everything is fine.

Nitrogen?

I'm using SunShine#4 with r\o water and I add Cal\Mag. Anyone have a clue what we have going on here? I'm also seeing some slight curling in the other plants (different strain, curious if it is related)

It's def. not nute burn as I'm only rolling 800PPM. Anyone that could help, I would highly appreciate it. I try to give back to the ROI community and will continue to do so.

nobody eh? someone has to have an idea here.

so this is a hydro set up??? if your leaves curl means over fert..

Soiless, SunShine#4. Not over fert, was running at 800ppm with very mature vegging plants. If anything, I would think it's under fert. Tonight I brought my PPM up to 1000 from 800 PPM. We shall see
