[Marius Swart]

Hi everyone, so im all new on the forum and not such a new aqua boy . okey. So I have a 3ft , ada , pressurized co2 , using all flourish ferts range and dsd . I have 2 x t5 39w, so 4 tubes, 6000k,6000k,8000k, not sure about the growlux. I have a veriety of plants in here, everything growing like craze,but as soon as hc gets leaves it dies soon after. Running a tetra ex700 canister , lilypipes and a 200lph powerhead.

Anyone can solve this?

What exactly are you dosing? Is it just Seachem Fluorish? Mark

Too much light. Turn off one of the fixtures. 2 T5 bulbs are plenty for such a shallow tank. What is the CO2 concentration and how are you dosing ferts?

HC requires high light, CO2, & fertilizer. It also takes time to become established as it's commonly grown emersed. If it's missing any one of these you get this result.

What all are you dosing - The dosing schedule is probably inadequate for the HC to grow.

I'm in the second week of my HC dry start and so far all the individual plants that I've planted are all alive and growing. I separated each plantlet apart and planted each one separately.
