Papa_Tanswered grow question 3 years ago Yeah giving nutrients is one of the toughest parts of learning as a grower.
I’ve talked with experienced growers who said that it has taken them up to year and half to get a good understanding of giving nutrients.
Don’t stress too much. Do your best and take notes. Always take notes. When things go wrong you have something to review.
I myself are still new enough that I’m also figuring my way around with nutrients.
Though honestly weed is pretty resilient so as long as you don’t make any major detrimental mistakes you should have something to enjoy.
