Here's what I would do if it were me (hint/hint). If you can change your res...change it then take number to 1000. Check in 24 hours.....I bet the beasts will have the number down. If the problem IS that....they should start to look better immediately but you MUST keep the number up.

If you can't change res....add 100-150 ppm of Pro Bloom.....check number and condiition of plant in 24 hours...(of course you are ALWAYS watching your ph)
Weedhound Reviewed by Weedhound on . Saggy Leaves One of my plants is starting to look sick. The leaves are looking saggy, leaf stems feel limp and noodley, and some of the lower leaves are starting to yellow around the edges. It looks similar to the way the one I killed last grow by over-nuting looked when it first started to die, but then I was running like 1800 PPM and now I am only at around 850-950 so I don't think it could possibly be over nuting. My pH is normal 5.6-6.1, temp is 69°, PPM is 850-950 and the roots look healthy. I Rating: 5
