Problems during flowering on 2 put of 5 plants

[Johnstuff]

I have 5 northern lights fem plants growing but 2 out of the 5 are very slow to start to flower there 3 weeks since switch and the ones with problem only just starting to show they are female. And have yellowing on leaves higher up the plant. And the new leaf growth hasn't grown out. Any ideas. Pics uploaded of the bad and then the good ones to compare. Thanks

you need 10 posts before posting pics buddy. Go to the introduction and say hello to a few folks.. and or post in general discussion threads. Pics with lights off and all the info on your grow would be much appreciated so we can try and help.

No problem I've chopped and binned them now and starting again with a different strain hopefully better.
