OTE="IndicaFarmer, post: 12287464, member: 921375"]Can 23w cfls burn? I let them get an inch or so close to them but maybe that leaf got too close one night idk. The other two look fine in the same ffof getting ro water with calmag. Do you thik because the cup is small all the nutes in the ffof are gone? Its only 9 days old Theyre usually good for 1 month without feeding in 1+ gallons[/QUOTE]
They can for sure burn and that is what it looks like to me, I done the same thing man, if it's just the one leave then that's probably the best guess!
