Houston, We Have A Problem!

Well, we're on day #77, week #3 of bloom, and we've got yellow leaves. The strain is White Widow x Big Bud. We're in a 5 ft tall, 3 x 2 ft space. I usually water once a week and use Ionic brand nutrients on a low dosage. If there's other information that you might need, please don't hesitate to ask me to help you help me.

I diagnosed the problem as a probable magnesium deficiency, and in the process learned a little bit about mobile and immobile nutrient problems. I'm 99% certain that we're at least dealing with a mobile problem. It seemed to start out at the bottom and has worked upward. There's a lot of purplish color in the stems on these two plants, but they've always been that way. Trichromes are still 99% white. Just started gathering crystals onto the leaves about 3-4 days ago. I've made it this far, really don't want the journey to end with a trip down the pooper this far into it. Pictures are included. Please let me know what you think.

Thank you for your time, folks.

 

Oh, thank you, sweet ganja-growing long-haired hippie Jesus!

I was reeeaaaaaally starting to get worried. I didn't realize that the plants were essentially going to start shedding leaves. That's an enormous relief! Things haven't exactly gone perfectly with this grow, but I'd say it's gone pretty well given that it's my first one.

Anyway, to answer questions.... This is day 77 in the "life" of my plant, since it sprouted out of the dirt. She's been in bloom since day #51. My dumb butt though, I forgot to switch from MH to HPS for two weeks. So, to answer the question specifically then, this is we'll refer to as "Bloom Day #28." We'll see exactly how long I let it go, but I intend to try and maximize bud size while still keeping the majority of trichromes white. Sure, I like a good couch-lock, but I got shit to do today, man, you know?

I apologize about the crummy pictures. Let me get you some better ones!

Little 10$ pH meter because the 90$ one that I ordered online didn't work worth a tinker's damn. Says my pH is high, which I'd probably agree with since I'm using a combination of bottled and tap water. Recommend a good, cheap pH meter? I'm not spending more than 50$ on the next one.

I'm not sure that this photo does justice. Here, the stems look a little more black/brown than purple, but it ought to give you a good idea. Do I need to be concerned with this coloration, or is that normal as well? User Media - TinyPic - Free Image Hosting, Photo Sharing & Video Hosting

In the last photo, I notice about 3 amber colored hairs (pistils or trichromes?) I also notice the nice little white crystals that I hope continue to expand on those upper leaves, and just generally all over the place. You think the phone will do well enough to give me an idea of the development of those little buggers? Would a magnifying glass work? I'll have to look around and see if there's one around. Lastly, I've avoided asking this question the whole time because I thought it was dumb, but I think we're getting to the stage where the answer can be determined with some degree relative certainty - what sort of yield can I expect?

Once more, thank you for your time in helping.
