i have searched for awhile now and cant find a definitive answer.
when growing in soilless, like a 60/40 sunshine mix/ perlite. should i be feeding a nutrient solution phed to like 5.7 or 6.7?

i have tested half my plants at each ph's the last two feedings and i cant see the difference, but im sure one will be better in the long run....

the soiless still has ph buffers, the ph changes as it dries,as long as it's between 5.8 and 6.8 you're fine, I haven't ph'ed in years and i run in pro mix

I've always rocked 6.0-6.2 in peat based soilless dirt like promix or sunshine when feeding salt based ferts, still do. ALWAYS works great
