Ok,My first grow.Made a lot of beginner mistakes.Overferted clones early in flowering and seem to cause yellowing purple stems and stripes along main stem.Growing is slower but not stopped.Flushed out a few of them and haven't notice any diff. from the other clones i didn't flush.So what more can be done? I let the leaves turn yellow loosing the green then cut them off.Even some lower airbuds wither away.Started using non -organic and now been giving them fish emulsion and liquid seaweed from now on in.I know there is yellowing during flowering but this is to much.Any suggestions Thanks Showgirl

pictures would help - could be a lot of things - inadequate lighting, pH problems, too many/few nutrients....

what's the pH? PPM?
