Rock*Star's first Hydroponic Grow DIY DWC Pure Kush Strain

This will be my first Hydroponic Grow and 3rd grow completely, still a newbie but getting some good knowledge from forums and I thank all of you for that! Cut some clones off the Pure Kush mother plant a week ago, so far so good. Cloning in a 4x2x4 Gotham Grow Tent with a 3.5 Gallon bucket, will be transitioning to 5gal buckets for flowering. Using GH Expert Flora Series Nute line up and for lighting I'll be using HydroFarm's 2ft 4 bulb t5' during veg and 400w hps hortilux bulb for flowering. Enough of my rambling here's some pic's of the setup and roots ! Thanks for dropping in!

I love rockstars! they are soooo delicious when I'm baked. Anyone else agree? Nice roots btw =P

Lol def rockstar rehydration

Need some help bad! I added 1/3 strength seedling nute to the DWC Cloner and a few days later I'm getting algae, root rot, or could just be from general hydroponic flora series nutes. The roots are collecting some type of material on them, its not slimy at all water temp is around 77 ph is 5.6 and ppm is 300 in R/O water. Also the leafs/stems are super red, purple & light green which I've been trying to research but coming up with no results. Could anyone please help me?

You've got slime! Examine everything you put in your res, ensure res is maintained properly (temp, ph, ppm, lightproof, ect) and start tea treatments.
