The smoke you got the seeds from almost definitely weren't pollinated by a male if they are from a commercial set up (ie. grown by some one to sell) in which case they would not want pollinated weed.(though there is always margin for error and they might of had a breeding program else where in the building).
Most likely it was pollinated by a hermaphrodite and care should be taken if these plant have a genetic predisposition to hermie.
Looking at your plants they look healthy and seem to be getting plenty of Nitrogen judging by the dark green leaves of the leaves looking at picture three (top row) that plant a good deep green.
Plant often lose a few leaves near the bottom as light availability reduces as the plant grows bigger and denser and nutrients are needed for new top growth.
Basic multi-purpose compost generally has 3-4 weeks worth of fertilizer at best ,in them, I can't comment on the Vitamix- pro as I have no details on it's constituent parts. It seems to me it is the worm castings that are feeding this plant right now but I don't know how long the nutrients in it will last as I haven't had a compost mix like yours.
Soil PH works between 6-7PH with the optimal mean of 6.5PH though it is good to let it range a little up and down so to allow all the different available nutrient to be come available.
As the soil dries out it will rise in PH. Your water is higher in PH than I would use but the dolomite will have a acid neutralizing affect plus it contains calcium and magnesium helping prevent cal/mag def.
Silicone is good for strong leaves and stems and the nitrozyme will convert any dead plant matter into usable nutrients.
The Betty's look larger than I would expect,I have recently looked into buying some of these and reading the blurb says they stay real small, can't always believe what you read.
Keep an eye out for any def which may show up as they eat up nutrient in your mix and show you they need some food.
Maybe try giving them some bloom nutes & carbs such as molases which as a bonus has magnesium in it.
Invest in a soil ph meter, you don't have to spend a lot on a electronic one there are plenty of reasonably inexpensive one that will give a fairly decent reading, but if you can afford it why skimp. This way you can keep a good track on PH.
Also keep an eye out for any male balls (nanners) on you bag seed girls.
Thats my 2 cents ,on the whole they look good to me.
I'm sure others will be along soon can give you more advise.
Have a good grow
