Hi growmie this is a advanced lack of calcium at your sd, the white parts could be the beginning of necrosis. Have a look at the Stiels are weak then it is 100% calcium deficiency.

@weefi, Before giving her 5 liters, i would calculate the required amount of water from the volume of soil i would take about 10% of soil as water. Because if this is a calcium deficiency the roots will be also affected and should be prevented from over watering because this will result in rotten roots and this would be the and for her and dangerous for the healthy ones because there are mold and bacteria that eaten the rotten roots and could affected the healty ones. So dont take too much water. il keep my fingers crossed, hope she will recover and getting big and frosty.

@Dendegrow, Based what you are mentioning now I had the same in mind. For this reason 10% was not possible. From my expierience I can say 7 liter per watering is the maximum if 100mbar are reached. I´ve splitted this in 5 Liter (incl. CalMag) and 2 Liter (incl. Potassium) More than this I can not do for now. 😞

@Dendegrow, I´m refereing to your response above: CalMag is from BioBizz and it´s on a natural basis there is no calcium nitrate if I´m right and yes I think you are right from the scheme itself. I will try to add the 5 liter with 5ml CalMag this is somehow the scheme what BioBizz also recommends 0,8ml/l if you are facing a deficit. At the beginning I only tried with 2 liter of water and 2,5ml CalMag. But due to smal symptoms also on WW I´ll try now your approach with 5liter, hope they will not be overfeeded. And for WW I´m sure that it is CalMag deficite (it looks similar to the deficite pictures) Tomorrow I´ll try then to change the Ph value if required. And again thank you very much for the support.👌 (It is my first grow I have no idea about deficits or anything😕, I red a lot at the beginning but expierence is a different thing) Yes I know sometimes it will be a painful learning process . 😣 As soon as the issue will be fixed I´ll inform.
