funny that stinky ive always called these stress leaves . i have a couble of b52 and they have over stressed due to mad ph fluxuatoin the first single fingered leaves were normal second set three fingered normal then they missed out the five fingered leaves and went straight to 7 fingered and then nine.The five fingered leaves must have been out on the town at the time of development so they sent out the 7 lol but it just shows the affects of stress but in flower they will start decreasing in leave numbers back down to the single leave.telling ye man this hydro is far harder than soil growin wish someone would have told me that lol.
