Go with the canna line for root products. Rhizotonic to treat it and help your roots grow.

Cannazym will take your dead roots and keept them FROM BECOMING root rot by turning them into some sort inert material or something like that....Stinky knows the real story behind it I'm sure and can elaborate with much more intelligence than me.

Forget hydroguard and that stuff.....I use botanicare as well and and love it but trust me......go with the Canna line for root health.
Weedhound Reviewed by Weedhound on . Wilt to Sudden death I am in DWC with plenty of air in the buckets, 4th week of flower, 1000W HPS, using GH nutes, PH stable at 5.4-5.7, nutes ranging from 600-700ppm, temp is 75-84 day, RH = 49-56%. Two days ago I notice the water level has not gone down like the other buckets which eat about a 1/4 gal per day and checked to make sure all the nutes and PH was correct. Everything checked out fine. Today all the leaves are drooping to an extreme measure as if the plant has stopped all water/nute takeup. the Rating: 5
