Your lights should come on and turn off at the same time everyday, are you doing that now?cuz you need to do that. you also need to fix your problems with the plants bottom leaves yellowing and dying, have you fed it at all? if so what strength? whats your ph? you are seeing either a pre-flower or a stipule, both are normal to see during veg when its reached maturity.
not being mean or nothing but if your going to take the risk of growing and all that you should really get serious about this. how much do you spend on bud a month? if you get serious and veiw it as an investment towards never having to buy weed again it doesnt seem like such a bad idea, does it?
