foliar feeding

[LinhT]

Thanks for the info guys. The reason I thought it was a light issue is because I read the following somewhere...

When light is increased, bottom leaves my start to yellow because nutrients are mobilized to other parts of the plants. The roots may not be able to take up nutrients fast enough. This is when foliar feeding may be important.

That was the jist of it.

BTW, Joe, forgot to answer your question. I have them growing in CHC/charcoal/perlite mix right now. When I first got them, I put them in S/H. Although I was flushing, I learned, flushing them the CORRECT way takes ALOT of water. I moved them to rockwool to experiment since one of the parents (kovachii) grows in association with decomposed limestone. I had roots all over the place but it's hard to maintain proper pH with rockwool over time so I think they started complaining again. Around the end of Summer, I moved them to the CHC mix. They're growing fine now, aside from the yellowing bottom leaves. I've done enough experimenting with them and will leave them alone now before they tell me to piss off for good.
