sorry ZZ, for the late reply. Just remember you can't OD the ferts, however, you don't want to waste the ferts either, cos they're not cheap!. You do need to dose the size of the tank. With that plant mass you could take it up to 8ml and see how you get on. I would just observe the plants on 8ml, because the mass is'nt that high.
thanks, much appreciated!
for the last three days I have been dosing 10ml TPN+ and 7ml EasyCarbo (got 250ml left, so why not?) is that still in the ballpark?
Once the Carbo runs out, should I scale back to 8ml TPN+?
When that goes I'm looking at TNC as a replacement. Anyone know if an analysis has been made on the actual content and if it's a good alternative to TPN?
