It really stinks that the one plant turned herm on you. Those are def balls on it, at least you caught it before they opened.
Mdawg seems to have exploded in size since the previous pics. That plant is looking great. My AK sprouted just hours before I made my first post in this thread. Today she is 22 days from sprout, and I don't see any preflowers yet. She has experienced a slight N toxicity and a Mag def just like yours did. I hope mine explodes like yours did. It hasn't happened yet, but there's still time.
cfls vs hps? I only use cfls, so I can crush a couple of the myths about them for ya. I have been a mj smoker for a little over 30 years, but only growing for about 5 years. In my experience, cfls will grow a plant that is just as potent and has equally tight buds, compared to a hps. The difference (and it's huge) is all about the final yield. Your going to have a possibility to pull about twice as much by using a 400w hps. I have been unemployed since I popped my first seed, otherwise I would have one as well. The largest area of difference should be just under the canopy, because of the better penetration that the hps will provide. One of my ex-roomates grows and uses a 400w hps to flower, and I admit that I am jealous of you both (in a good way).
I was looking back at some earlier posts in this thread and was wondering.....what ever happened to those other beans you were trying to pop? I wanted to say that I would not recommend keeping them under water for more than 12-24 hours. Some can stay under longer, but it seems to depend on the strain. It is quite possible that they were drowned. The taproot that emerges is the beginning of the root system, and roots need oxygen. I used to put mine in a glass for an hour or two, then move them to the paper towel routine. I have found the "put them in water" step to be unneccessary don't do it at all anymore.
I think I've typed enough, so I'll stop now. Keep lovin' Mdawg and she will make you proud.
Peace bro.
