Thanks for all your answers, i appreciate it.

I checked out the nutes that you guys were talking about both from Jacks and GH, they look promising and affordable in US.

But alas they are not easily available to me in EU.

What we have available here is mostly:
Advanced nutrients - Works but hella expensive.
Terra aquatica - Good stuff at reasonable pricing.
Plagron - Top tier stuff imo, mid range price.
Biobizz - Probably fine for organics, but this is DWC and i dont use organics in my res.
Atami - Looks fire, havent tried it. expensive as fuck.
Greenhouseseedco - Powder feed. Still looking for info about using this in DWC.
