U mean my next run in the light mix? If so do you reckon is should mix it all up well in advance or just before potting.
I spoke to a guy at growell and he basically said allmix just has a higher nutrient content I.E added premix. I wouldn't say it's definite but he must know something working for them lol
And yer @Eyes on Fire. You've both had my back and I truly appreciate it.
I've got everything on your list @Dazed apart from the all mix ,silica and humic acid.
Yeah just bump up your lighmix for the next run. I'd mix it now, doesn't need anytime to cook really-just there to help along. I haven't heard of premix before mate so I can't comment on that.

I personally wouldn't mix that much if I was trying out a mix, harder to re-balance it later on if it's not on point for YOUR setup. Try not to think about it as adding stuff to a soil for the plant to take up, try to think of it as recreating a really fertile soil that has all the right things at all the rights times, it's actually really difficult to do and takes a lot of tweaking. I made the mistake of taking sub cools recipe and doing 'my version' and thinking it was golden, it wasn't, still ISN'T.
