hey so i'm really new to growing. i just have a very basic set up with a three lamp flourescent ballast overhanging five small plants... the entire thing is closed decently with cardboard and vapour barrier over the top to keep in some moisture and i have a small fan running to curculate air in the system. the lower leaves 3 of 5 plants have gone brown and look ready to fall off and there are some brown patches on the edges of some of the fan leaves. they were like this for a few days and then i transplanted into bigger pots, and started using a cil- bone and blood mix that has 7-7-0 mix in it just to try and give it that kick start. i have only given one things of nute when i transplanted and plan once every two weeks or so so i don't burn them.

i was wondering if there is any thing in my setup that would be making those leaves go brown, if they will get better now that i have upped the temp to around 70, mid humidty and started nuts, or if there is something else i need to watch out for.... the plants are only about 4 weeks along so it would be a dissappointment to lose them before i even gender them
