I had a problem of all my leaves turning yellow. I fertilized with both Shultz liq plant food at 3/4 strength and a little blood meal. new leaves look dark green and vibrent. but the older yellow leaves are falling off. Is it normal that it is impossible to save the older leaves. Some of the plants where the leaves fell off now have 6-8 inch stems before the first set of leaves but when you get to the leaves the nodes are close together. and the stalk is stiff. will these long stalks be a problem later on?

Thanks.
