Thanks DW, you're the man !!
Check out my mini forest:


One last question, I have calmag deficiency in only about 4-5 leaves, all my other leaves look green, lush, and healthy. They are mostly on my second plant (closest plant to you in the picture), they are on most of the fan leaves on the main cola and a few on the side branches of this second plant. Should I be worried?
