Blue dream and Northern Lights

So Ive been testing a theory that I can use the kratky method to get all the way through veg without a water change, as the water goes down, the tds goes up, this has mostly held true, and I noticed the ppms raising slightly early on in veg, but now ive noticed them dipping slightly, and so Ive added some more Grow nutes. My 4x4 is about done being setup, I dont have the budget to make it rdwc proper, but I finished return plumbing on the 4 sites, so that once I get a pump system, it should be plug and play to go full rdwc, for this grow, it will have to be essentially a 4 site bubble bucket system Ive hung the air pump above the waterline to prevent flooding if it fails, and the plants in the veg tent will be going in the 2 front sites, the rear sites will remain vacant for now I took 2 clones from each plant, dipped in clonex rooting gel, then placed in root riot cubes, soaked in clonex solution at 5ml/L Theyll stay under 24h light until I see them develop roots, then Ill keep 1 of each of the best Sorry for the lack of weekly updates guys, ive been busy with life, but ill try to stay on the ball in flower, I know yall love to watch buds form.
