Need some input...

Hello all~
I have a question. I have white fuzzy lookin mold on my roots (not my question) (will get pictures on as soon as i find my memory stick) Will be flushing my system tomorrow, getting new nutes and picking up some h2o2. I have a 2.5 gallon bucket rigged up with coco husk as the medium. I was using my hydro stores own brand of nutrients, made in store ( supporting the locals, ya know?) but i want something with proven results. Oh ya, currently my ladies are Master Kush, but i will be getting some Purple Lightning, Bubblegum, and Strawberry Cough very soon. So consider them too. I would prefer going organic but i really want something that wont clog up my hoses.
If you didnt get it in there, my question is, what would the best nutrients be?

I use the GH Flora series and have no problems from day 1. If dont have a ec/ppm meter you can go with directions right off of bottle and tweak to your liking.

White fuzzy looking mould sounds serious ? Never seen that.

I tried to get a pic of the fuzzies for ya but I smoked a bowl:jointsmile:, doubled the water pressure and it seems to have rinsed it away.
