Purple Limeade - daily pics and updates

Starting week 2, plants look lovely. Day 8 notes: Tiamat has got a fair collection of roots in the res, while Apsu is just dropping her first taproot. Everything holding steady, so we'll see as the week goes on. Day 9 notes: Both plants are growing great. I tried to take a shot of the roots, but I need to take macro off, the shots I got were so blurry I decided to delete them and try again. Day 10 notes: Nothing to report. They're starting to grow fast. The roots move too much for my shitty camera's stabilization, so all pics came out blurry still, but at least you can see them. Day 11 notes: Tiamat is now showing some brown spots on her lower leaves. This is extremely troubling. I'll be asking a question about it. I'm really not sure why this is happening. I don't know if it's happening with Apsu, as it did come up a couple of days later. Day 12 notes: Mottling is getting a little worse, but today I changed the reservoir with the Week 2 recipe, so if it is a deficiency, it will be cleared up soon. Thank you to everyone who answered. I have been going feather light on nutrients this time, so it makes a ton of sense for it to be a deficiency, and it even looks like one, now I know what it is lol. Other than that, the plants are definitely still plugging away. I took a moment to reflect just now, and it's hard to believe that in just about 2 months, these plants will be about ready. Day 13 notes: I hope I'm overreacting. I hope I hope I'm overreacting. So I saw some chunks of brown crap floating around in my res. It appears it accumulated around my tubes originally. I saw a few chunks caught on my roots and immediately thought root rot. There isn't a strong smell, not unlike the smell in my bottle of Hydroguard, but much stronger, but I don't want to take the chances. I'm tossing my bottle of Hydroguard. Thank god I still have my Voodoo Juice. Maybe it's expensive, but I don't get anything like that with it. Apart from that, the roots do not appear to damaged. In other news, the mottling has stopped dead. The plants seem to like the new mixture. Day 14 notes: Voodoo Juice - Accept no substitutions. I'm not advertising, I'm just a very happy user. After the debacle with brown bacterial bloom in my res yesterday, I went straight to my fridge and got my leftover Voodoo Juice, measured out 20ml for my 5 gal res, and squirted it straight in. Since then, I had to wait until today to give it a chance to make a difference. When I inspected my res today, I was blown away. The water is noticably clearer, and where yesterday all of the lines were thick with brown growth, today a large majority of that growth is gone, and what remains is thinner, peeling, and has turned white. I expect that after tomorrow the bacterial genocide should be complete, and then I'll probably squirt in a little Sweet Raw to boost their numbers. In other news, week 2 has officially come and gone, and I still love what I'm seeing. Mottling has completely stopped dead since the new solution has been added, so I am very confident in the potassium deficiency diagnosis. Looking forward to week 3: I plan to FIM each plant during week 3 when they're ready. Other than that, no other damage is intended to either plant. Other than that, I can't wait.
