On April 16 I flip to 12/12 light schedule and within a few days the plants have gone crazy and i sneak off a few lower branches hoping it's not to late ! 2 days later and i think im fine the plants are eating nutrients and sucking lots of water.. April 21 the plants are thriving pretty good and I find one of the plants are mutating. A single leaves are coming thru the top of a full mature leaf.. on some 2 single leaves. I wonder if chopping some branches just 2 days after flipping the light schedule has caused this ?
