Sour Mandarina x Rosewater Cookie

PH hit the roof peaking at 8.0 before the flush and new solution were introduced. It kept climbing for a few days before it stabilized at 6.2. I found out that I have plugged the dwc system with the timer, so the water did not circulate for 6 hours for 2 days straight 😱 One of the seedlings looks bad to me. Last time that happened to one of the seedlings it was very slow in growth and new brown spots were popping up on every new pair of leafs, even after the water conditions were stable. Still water never means good 💀 I kept the room temperature a bit too high, around +27C. Lowered to sub +25C. Solution EC started at 1.2 and risen to 1.3 after adding the Cannazym. Changed the solution twice already 😑 Otherwise, THEY ARE GREEN AND HEALTHY LOOKING 💪 Bluelab's PH pen and EC-meter are the best buys I have done lately. Strongly recommended for every grower in consideration of getting one of them 😎
