Thank you both @Philindicus and @CRiSPrGrow for your interesting answers.
I'll take another closer look at the ladies tomorrow.
I water my girl when needles, I feel the pots and their weight, I'll let them nearly dry and give them 1.5L water every 4 to 5 days. My water is bottled, the pH is corrected to about 6.5.
My roots went to the pot edges about day 25, the soil I use is Atami Bi grow. The 2 main-lined had no problems, only the 2 topped girls. They need more water due to more leaves so they get more. But they never sit in overwatered pots.
I use mykorrhiza/bacterias by Green Buzz Liquids as recommended, also giving hinidic acid by Green Buzz Liquid as recommended. So hopefully I have no mold at my roots. So it seems I could need a E. - meter to measure the drain. I have to give them about 3 Liters of water to produce any drain, twice the amount of water I usually give them.
