Man I wish there was a WP 50 years ago !!!! Reading thru the previous answers to this question made me realize AGAIN, how many GFG (good fuckin growers) I just made that abbreviation up...he,he,he, there are on WP !!! I'd also say stress and possible heat or environmental changes, created by the move, can cause yellowing of lower leaves. Be patient . Happy growin OD !!!
