Hey man! So
@420autoflower put me onto this. He's the guru on this.
For this grow all I did was plant into
OF which lasted about 4 weeks initially. Been considering going with some promix next run but that would mean getting a veg top dress. DTE has a bunch of different dry amendments so I'm sure they have a good veg premade like the bloom. Or you could mix up your own with individual stuff they sell. Personally the
OF costs just as much as other soils for me so I just use that so I don't have to mess with veg nutes.
After the 4 weeks I top dress with 1/2 cup of DTE 4-8-4 every 7-10 days. It was 1/3 cup every 10-14 but that has proven to be on the lighter side for my hungrier strains so I bumped it up. Other than that it's just recharge every 5-7 days. I water with my RO water that I add +50ppm calimagic, yucca, and pH to 6.5 and just pour it right over the top dress.
With you using sip buckets it might not work due to having to water in the top dress but you could do an amended super soil that could last a whole grow with minor additives like recharge. That's the route I'd go with those. Here's my super soil notes I've taken if you're interested. Pulled the first mix off someone here on AFN, can't remember who. Second one is Daz from night owls mix
Sometimes, just adding a little of your admix as a top dressing will be all you need, or even better, fresh worm castings! I feel that you should also keep a few items in case of deficiencies. Blood meal for FAST doses of N, kelp meal for K, molasses or alfalfa meal for P, lime and Epsom salts or Cal/Mag for calcium and magnesium. Use these if you see definite signs of deficiency. N in particular is easy to spot.
