Auto Speed Bud from Female Seeds

Going into week 4. After. A transplant and at the end of week 3 they have seemed to recovered and are doing great. I’ve noticed that they “pray” towards the light so they seem to be happy. Using 1ml of cal mag. When I water. Ph. 6.1 -6.3 of 90%RO 10% tap. Added the second mars hydro on day 25. Update last day of week 4 day 28. The ladies ain't looking too happy. Being hit by I imagine Cal mag deficiency. Even tho I was expecting it because of the RO water. It seems I didn't add the Cal mag fast enough. Hopefully.the 2ml/L or Cal mag. Will fix it. Last watered 250ml each of PH 6.2 water on 8/28
