Ok, thanks, will get some TPN+ then as Id like to actually keep some plants alive this time round![]()
Considering you have low light, and fairly heavy stocking, you may get away without adding NO3 & PO4, although there is no point buying this to find they will end up with defficiencies so you will have to pay out again for another fertiliser!
It is always better to add more than not enough though
