seems it could be your light is a tad to close on those taller plants notice the leaves are not as upward as the lower ones?

place you hand(backside) right under the light where the plant top is and if your hand burns its too close it should be just warm not too hot, are you feeding them yet as well?

they look good just keep an eye on them so you dont burn them up by mistake
invision Reviewed by invision on . Look good? Living in Paraguay right now so its legal to grow but just wondering how the pros out here think they are looking. all been vegging for about 4 weeks or so. just put into flower today. they're all sopposed to be indica but 2 came out very sativa looking. and one got a little dried so it did get a little stunted.
