Ec too high
Hashyanswered grow question 3 years ago
Not sure on your pen but that reading may be equivalent to ec 1.145. So your running autos which I find top out at an Ec 1.2-1.4. Get your water and test that 1st. Write it down, eg mine is Ec 0.185. Then add 1 ml of each nute you use and see how much each one raises it by. From that you should be able to dial in how much of each product you want to use without exceeding the Ec. Good luck

Triple-leaf Speedy Chile: what is growing there? Why becoming yellow?My triple-leaf Speedy Chile (see also week comment for more info): 1. The 3 cotyledons have become yellow. I also see on lower leaves slightly some yellow tips. Nutrient deficiency? Underwatering? 2. What are the small leaves coming out of soil. Another plant? Should I remove?
