1st indoor grow:RQS PurpleQueen/Critical

I added calmag when i received it, 0.8ml/l, afterwards i continued to water with 0.3 per watergift, THIS WAS A MISTAKE! Apparently you should only add it once per week, because i gave to much, the plants started to dehydrate, because the soil got more salty, and in turn, sucked water out of the plants, instead of the plants sucking water out of the soil, due to osmosis, and that nature will always try to balance the amount of salt in connected spaces, by adding more water to the higher concentration, so it will lessen. I counteracted this by adding rainwater to the plants, close to 2l per plant, sucking up the water on the bottom, aswel as moving the plants into a bigger pot with fresh soil filling up the new crevices. no nutrients were given afterwards due to the large amount of nutrients from the previous days, i will continue with my feeding schedule within the next week, also thinking about putting them on 12/12 next week, depending on how much the top shoots develop, i would like 3 nodes atleast.
