Day 4 of Flower - critical kush

Day 4 of flower... bud sites are just starting to develop but not much to look at yet so i figured I'd lift her skirt and give yall a little peek... For those who didn't know, all my grows are hydro, no soil... I'm too old to be playing in dirt 😂 but this is actually a technique that has even more benefits for soil grows...
In addition to my main nutrient mix, I use a supplemental surfactant(wetting agent) to break the polarity of the water molecules, resulting in less surface tension which helps with water dispersion throughout the root zone
