what is my pland doing? the leaves are growing white hairs

Hi ive just sighned up so im new here. been growing since 1998, indoor and outdoor. i dug up a plant that survived thru winter and harvested most of it. i then potted the plant and moved it into my hot house. it went into regrow. it is its second season and the plant has just started to produce white hairs. the thing is the hairs are shooting from between the fork part of the leaves. ive never seen or herd of this. does anyone know what going on with it? im in Australia and it hit 52 degrees celceous outside so in the hothouse it would be much higher temp the other day and the plant got heat burnt a little and would of gorn thru shock. i got water to it as it was drooping and almost dead but its ok except now my leaves are trying to bud. has anyone seen this before or know what is going on with my plant.
my phone camera is crap ill try and add crystal clear photos asap. try zooming in and out if possible

It's almost impossible to really see what's going on in your pics but I had a plant that grew calyxes and pistils in that same exact place. It didn't seem to effect the yield at all, I just had random leaves with a calyx or two. What was your last harvest like on this plant? Did it show the same mutation? If it continues to show weird mutations you might just want to pull it...or keep it as an experiment.
