first grow plz leave comments

starting first indoor grow in small space roughly rectangular 80cmW x 260cmH x 60cmD. growing 2 strains wappa(3) and buddha(1) on week 2 and a bit the now plants look pretty healthy i think (see pics). started under 220w cfl now switched to 250w mh progressing to a 250w hps come flowering. some small problems that could do with clearing up so ill start at the beginning problem1 is 1 of the wappa has 2 leafs with a kink in the exact same spot on both opposite leaves looks kinda wacky will try get close up pic of it. problem2 is some o the older leafs under the big leaves are turning all yellow and parts of the ones above are slightly yellow around the edges, pretty sure it aint nutes as soil is a bio bizz all mix & have just started adding bio grow nutes at a quarter of the dose cos the plants are still early. all help appreciated.

they're looking good man. wouldn't worry about the kinky leaves. if the yellowing leaves get much worse i'd stop nuting them altogether and give them a good flush with just clean water. look forward to seeing them grow up, good luck!

thanks man the wappa with the kinky leaves is looking a bit weird all over hopefully not gonna go wack. leaves are starting to go dark now under the 250w mh just started on 18/6 at the weekend on the mh n noticed a huge diff between the fluro n the mh worth the extra 25 bucks for any1 else reading. also got a small intake problem if u can help how important is an intake the now ive a unfanned intake sitting out my skylight with a pair o tights over it (advice from a fellow grower) im thinking that if airs coming in without the fan theres air getting out the same way? i do have a 100mm outtake with a carbon on it but is having an unfanned intake make the outtake fan pointless? also looking for feedback on bat guano and bud candy for the flower?

just adding a wee update for u grow followers. 2 and a half weeks into veg n after only 2 6 hour sleeps plants are starting to get some hieght still think they look a bit bushy compared to wot ive seen but must be a good sign of healthy growth no? also got a pic of kinked leaf for more accurate diagnosis lol. got myself a book 2day by jorge cerventes pretty good read lots o pics but a bit weak on problems and diagnosis so ill stick 2 the net 4 help think we can see sex coming through at the nodes does this sound true based on the pics? no hairs yet but there is 2 sorto green bits sticking out my nodes lol.
