Lol whoops I didn't realize I was replying to the Build a Better Soil thread with that, meant to ask in the Landrace Genetics 101 thread, but thanks for the advice Timmo!
So far so good with the soil though. It's a little hot for them I think to be honest, but the growth still seems good. They're growing, there's just some little burn marks at the tips. My "Base Mix" was doing that too, I think the EWC I got was a little hot since they also added kelp meal and rock dusts to it. The original Base Mix was 33% EWC, 33% Perlite, 33% Peatmoss. Using that, I added 2 cups neem meal, 1/2 a cup Bio-Live and 18 tablespoons of Azomite to 2.4 cu ft ( 18 gallons ) to make my "amended mix". I wasn't liking how the Base Mix was draining, so I added a heap of perlite to it, changed it to 50% Perlite, 25% EWC and 25% Peatmoss. So then finally I mixed the revised Base Mix 50/50 with my Amended Mix ( after it cooked 4 weeks ) and transplanted them into 3 gallon pots with it.
I'm a little concerned, since they were initially planted into Happy Frog, and then those solo-cup sized root-balls were planted into the original Base Mix (which seems like it was burning tips already but was growing well ) and then transplanted that gallon size root-ball into a 3 gallon pot with that 50/50 combination of revised Base mix and Amended mix. I'm just hoping that as they get bigger they will appreciate that more nutritious layer on the side, or just instinctively stay away from it if they don't like it.
I really don't think your soil is causing nute burn. I would chalk it up to heat stress complicated by low humidity. In all the research I've done in the last few years, one of the few things I can say that EVERYONE agrees on is that EWC is about the most gentle thing on plants there is. Even spiked with kelp, because that's probably number 2 on everybody's list of things you really can't hurt a plant with. You're not adding a ton of neem, biolive, or azomite, so I would think that a solo-sized plant could handle it just fine. Certainly a gallon plant could.
And yes, the bigger a plant gets, the more it will appreciate a robust soil, at least for most strains.
