Stem failure
 
Okay so about 2 months or so ago I had a big melt. I have since fixed that problem and the plant that made it through that are coming back but the new plants are starting to show sign of something going wrong the stems at or just above the substrate are rooting away and the plants float up to the top what could be the cause I dose root tabs, NPK, and Iron an such 3x to 4x a week. The top of the plants are growing really well about two inches in the last mouth. So what is going wrong.

Not sure but the old leaves on some other stems are kind of Holy as well.

With a melt like that. You should trim and replant the tops of your stems. You're typically not going to get growth out of those bottoms again. Every once in a while you will, but I think you're best to just trim it,and not rely on hopes of what night not happen. Lol

I pulled out all the bare stem and trim off the tops and replanted them they are growing back fine some of those lower leaves are starting to get holy.

But its the new Red Ludwigia I put in to replace the dead stuff that is showing the stem root?

You may have a deficiency of some sort. But it's common for old leaves to age. Lol

Lower leaves developing holes can be a potassium deficiency. Try doubling up for a week to see if it stops. Old leaves will not recover! My stems needed more magnesium, when I dose 3 tsp after each water change in my 200 gallon system they are healthier. I did that on a hunch after increasing flow and bumping CO2 did nothing good. My GH ought to be fine but a bit more was better. Increasing the hours the lights were on was another experiment that succeeded. Keep track of how much you are dosing and change one thing at a time to see what happens. It can happen quickly as you have already noticed.

I get side shoots out the yingyang when I leave the bottom trimmed portions in the tank and replant the tops elsewhere. It is the way to get very thick busy stands of stems. Trim and let the side shoots grow, then trim the side shoots and you can double sometimes quadruple your stems in a very short time. There are some stems that do not like to be trimmed, but most LOVE to be trimmed.

Ill try bumping up the potassium thanks

Well I'm dose heavy now for about two week and have started double doseing the Pot well I cannot believe how crazy the stuff has started to grow. I hope the bottom of the plants fill in a little more. Pics to come. Hopefully the leaves do better and stop dead and the stems thicken up.
