I’ve two sour d auto they start seeling on april 9 and on Friday is go to start the second week and how much on teaspoon I need to add for both plants thanks
Most won’t need cal/mag until flowering in Happy Frog. I use HF and never introduce cal/mag until flowering.
Welcome ! With your Happy Frog soil you should be good up to 4 for 5 weeks without adding anything.
Thank for the advice and happy 420
