It was all going so well

[tankN00b]

So the CO2 is going in, I'm dosing additional MgSO4 to get this closer to 10ppm and I've got some 8% DTPA which I'm adding at 0.5 ppm.

Question - should I be cutting back the plants to remove the sad leaves and give them a chance to grow back fresh? Or is this going to stress them more?

Thanks!
