That's why I make sure they have proper setups.I've given away some nice clones to folks who promise to take care of them, but don't!
I make then all order the 3x3 Mars kit with the 1000, and the 2500g of Mega Crop before I'll even consider it. lol
That tall one (Darkstar KushxLavender) I showed the other day had a twin sister that I gave away a month ago. Went over to check on it the other day and instead of SC, his "buddy" told him to top it. He's in W3, just started showing flowers and he nipped about 2 nodes off the top. I gave him alot of crap about it, but what can you do.
He's getting ahead of himself on the MC too. He said he was already at 24g per 5 gallon, when I hadn't even told him to jump from 4.5g yet. Plant looks healthy, but if he keeps going on his own, he'll end up torching it I'm sure.
