hydro troubles

[L~B]

ok guys its been years since I have done hydro.... and It shows...here are my girls the hydro system is 4x12 48 ebb n grow buckets sittin under 3k 5-600s the ph is 5.8 the ppm right now is 980 I am feeding pbp at 15 ml per gal lk at 10ml per gal and the same with sweet is this under feeding?

Looks like underfeeding. 15 ml PBP is pretty light, especially with 5 x 600w. Go to 20 ml/gal and give it up to a week to gauge results. Also, they look overwatered, dull and drooping. What is the watering sched?

Please fill out the Infirmary form for hydro for more info.

too weird didn't see your post... they get watered every 4 hrs for 45 min 30 is just not enough I am only running 4 lines off my control...there are 2 air stones in the rez running 24/7 so the roots can handle the submerged time.... off to change the rez I'm going to 25 ml per gal.... the reason I am doing a full rez change as it looks like all the available n has been depleted already....

Try 20 ml first. You don't want to go from not enough to too much right away....

I would back off the waterings to 45 min every 6 hours and observe, to give the roots time to breathe. It's possible that with the slower metabolism from the lack of nutrients that the roots find the watering a little to frequent.
