Thanks, that helps.
I do most of veg in smaller containers and then up pot to final containers 2 weeks before flip. I've always done this since both flipping and transplanting are stressors and didn't want to do them together. Maybe i have been over cautious in this respect? When you say you transplant just before you flip, do you mean within a day or two or are you giving it a little more time than that?
I'm trying to build a pretty robust soil, but havent had it through a full run yet to see if it will last an entire 11 weeks (2 weeks veg plus 9 flower) yet. I'm finally finishing the transition so should have a better idea in the next couple of months. As I transitioned ive been supplementing with age old bloom once a week to try to head off any nutrient deficiencies which has worked well, but we are now dropping that to see how the soil holds up. I may grab a few spikes to add about 2 weeks into veg as a safety net
My current mix is:
26 gallons sphagnum
10 gallons ewc
8 gallons pumice
7 gallons rice hulls
1 gallon insect frass
1 gallon bio-live (fish bone meal, fish meal, crustacean meal, alfalfa meal, langbeinite and kelp meal with beneficial bacteria and fungi)
4 cups each of azomite, basalt, gypsum and oyster shell (i'm bumping this to 6 cups each starting next mix)
2 cups neem
I'm adding 2 cups kelp meal starting next mix
