Wedding Cake Hydroponic LED mini grow

Vegatative seedling planted in the basket, sproutpad put into the hydroballs. The water splashes upon the bottom Of the basket, lets wait for the roots to come through. To achieve the perfect EC I use 1/4 zero water and 3/4 tab water For the balancing of the PH I have put 1 ML in at a time and let it rest for a few hours. After 24 hours the PH was 6.3 which was a tiny bit too high. This morning added 0.5 ML on 20 liter water and it was reduced to 5.85. Lets see if it stays stable.
