sorry but I do not own a camera to take pic's w/ so i hope all my information help's in giving some advice. the leaf stems are very red colored, and the leaves at the tops of the branches by the flowers are getting a really bad ram's horn to them. Plus the main stem has what look's like red vein's showing through. the leaves continue to yellow and eventually fall off or dry up and it is all the different leaves not just old or new. thanks in advance for any helpful advice.

really i have never had a problem w/ my Ph before being that low. I use hydro-soil's lucas formula of floranova bloom at 8ml/g at a ph of 5.2 to 5.4 and then feed when the ph raises and haven't had a problem. the growth dosn't seem to be fazed to much from the yellowing of the leaves an the rams horn,but it's not as it should be this is my second run w/ this plant. But today when i ph'ed the water it was at 6.5 before i lowerd it to 5.5 .

I'm thinking about dumping the bucket tomarrow and starting w/ fresh nute's at half the amount and phing to 5.6 to see if that helps. but i just can't figure out why there is red vein's running vertical up the sides of the main stem. and the rams horn is only around the flowers and know where else.
