Hi bud! Great job so far! I would do a good cleaning of your tank and use peroxide to kill any germs. Get 3% and dilute it a bit for cleaning and swabbing down the tank really good.
You should also consider after you get tank and airstones all cleaned up go back with just straight PH water at 5.7 and a little H202 for like a day (to flush the plants and kill any bad guys floating around in there on your roots causing trouble. There is a 8 step method you are can follow for step by step details) and then drain tank again , flush and clean tank again with h202 then fill it back up with your normal nuts blend.
Did you not like the SH nuts (just curious as Im gonna be trying them soon)? I just ordered the high end kit for growing bubbleponic with HID lights. I use 2 400w lights. One is a MH buld and the other is HPS bulb.
I really havent had a chance to try the regular SH nutes. Did you use the SH stuff at all and if so what strenght did you use it at and how old were your plants and size at the time?
Also, what I was told by the SH guys is when doing seeds in a Bubbleponic, its better to leave the plastic on that comes with the RW cubes. You wanna place the water feed tube directly UNDER the RW cube which should sit on some hydroton rocks about 1/2 to 3/4 inch to a inch dpending size of your net pots. COme in almost at the bottom with your water feed tube through the net pot and make sure the water feed tube is touching the bottom on the RW cube. This way the RW cube doesnt get soked and stays together nice and neat. Also, this forces the roots to grow down!
YOu started off with ALOT of stuff for the first time! YOu really came along way really fast and just dove right in! I like that but I was gonna suggest start off simple for the first time but its a little late for that now ..LOL you ass deep in it now brow...clones, seedlings, cuttings, soil plant..jeez mang!
Keep up the good work!
