I had the same problem as you with slime in my first DWC grow. To make sure it doesn’t come back you need to put some beneficiall microbes in there to eat the bad stuff. Worked great for me. Have a google and if you want to try DWC again give the microbe tea a try.
Hello. On your week 5 of veg, on your first picture, there is yellow spots on one leaf. What is it? I have the same sometimes and im wondering if its dangerous or normal. Im at my first grow. Thank you.
@Tabarnak,that plant had slime all over the roots and was on its death bed. I hope that is not the case for you! I can tell you most problems are ph related. Best wishes
