well i decided to star growing my own so i got the stealth hydro package with everything needed to start. at first everything was going well but over the last week or so first off there is what i guess is algei it brow and slimy. the next problem seems to be that the ph of the solution will rise by up to 4.5 to 7.5 in just a day. also the roots seem to be rotting and growth has slow to almost nothing. my seed were mystery seed i didnt want to spend a bunch on seeds if i got them killed.i also have a foam collecting on the top of the nutes solution. the other thing is that i have one tomato plant growing with them is this a problem. if anyone can give me some suggestion to help that would be great
