I think they will pull through! After the h202 rinse and adding a touch of bleach to the nutes, the plants started to rebound. I was about to trash them and actually started some new seeds.
But! I saw a few leaves starting to perk up. Checked the res and I had an explosion of new root growth! Then the plant started vegging like normal again! I am going to be using hydroguard in the res from now on as a precaution.
I put the scrog back in and we are on our way again! Now I can start back with the spider mite treatments and we should be in the clear. The mite problem has improved as well, hopefully I should be out of the woods in a couple weeks. I'm also going to be applying azamax weekly as a foliar spray just in case
