Fast Buds - Living Soil - White Widow Auto - CBD Auto 20:1 - Sour Diesel Auto

Day 49 - Gave some AACT everything looks good till this day. Day 51 - The leafes of SD got more and more brown areas. See pictures. No idea what it could be. 1st try of healing solution: Created 1 liter banana extract(to get Potassium) added 2 liter water and 2,5 ml CalMag to be on the safe side. (Baseline BioBizz deficit reduction scheme 0,8ml/l) Also the tips of some leaves stick out towards the ceiling. For now I‘m only facing issues with SD, if someone has an idea how to fix the deficit issues with SD happy to get some support. WW is looking great, the shugar leafes are becoming more and more and her buds are growing. Update on my Question: (System is not allowing me directly to answer on your comments) AACT is compost tea. 5 Liter destilled + 2,5 Liter Water, 30g Molasses and 1 Liter worm hummus. Brew time 26 hours. A bit of the worm hummus was falling in my soil bed, when I was watering with the AACT. I removed the worm hummus from the mulch layer now. Started a bit more watering. To change the light cycle is not so easy I´m running a dehumidifier already and get around 65-68% humidity. If I turn of the lights humidtiy immediately increases. I plan to connect the dehumidifier in the next das directly to the tent and maybe then I can change the cycle as proposed but i'm still waiting for an exhaust air duct that i can connect. Day 52 - SD is still keeping not well, the brown parts on the leafes have extended. Also more leafes are facing the same symptoms. WW - First small brown dots are appearing. In the meantime Plagron PK 13-14 has arrived. Added 1 liter water incl. 1ml PK in the root area of SD Added 1 Liter water incl. 1ml PK in the root area of WW. (Baseline Plagron PK fertilization scheme 1ml/l water) Day 53 - Feedback to all your valuable support - Fist of all THANK YOU ALL (Sorry but there is no possibility directly to reply to your feedback) PH value I can not influence at the moment, it is not that I not want I´m not prepared for it. PH/EC meter and PH +- is also on the way, things may arrive tomorrow. To be honest I thought the living soil is maintaing itself. At the moment I only can have high hopes that the added PK will stop or slow down the further spread. Yellow leafes seem to be fully dried out and what I also observed that first old leafes have been affected on the bottom and now it seems to spread to younger and to the top. To catch up wit the topic root rot, I can say the hygrometer value in the soil is always around 80-100mbar. (Blumat auto watering setting) I also try to dry it out a bit more to get value around 200mbar to be on the safe side for the time without light. But first I want to check to get to 6.2 Ph value but without any possibllity to measure it I have to sit and wait for my order. :-( DLI was at around 45 per 24h. Cycle changed back to 18/6 with DLI 45 per 18h now. I´m only scared about rod. Hope I can somehow maintain the RH. In the meantime I´ve checked my water values and they indicate magnesium deficite. (Inidicator that I should start with empsom salt.) But I already gave CalMag 2,5mg/3liter. I´m only wondering that only one plant is really affected. Happy about every feedback, try to consider everything what all you have shared with me. But it might take some time. Added 5 liter water with 5ml CalMag. (BioBizz) Added 2 liter water with 4ml Potassium. (CANNA Mono Potassium 16% P) - Just recogniced the purple stems of P deficit. Day 54 - Most important the spread of brown leafs seems to have stopped and I can say mostly all of you have been right with your feedback Ph 5,2 in the soil First try with BioBizz Up - Added a solution of 200ml incl 0,5ml BiobizzUp Day 55 - Ph 5,3 Added 5 Liter Water with 20ml BiobizzUP (Target is to increase Ph max 0,3 per day, for a healthy increasement) + 5ml PK Directly after giving the solution the value increased to 5,4 I think the liquid solution is not the best way to increase the value, because always watering is required, what would lead to other issues. Because of this the target is to change in a frew days to dolomitic limestone powder. This adds calcium, magnesium and raises the Ph from the acidic soil. In addion the CalMag sympthoms of WW have spread a bit but not dramaticly.
