Can anybody identify this problem for me? I have already flushed the medium because I can't figure out what it should be based on deficiency charts. I am also keeping my pH around 6.2. It is on the older leaves and the buds still look fine. 5 weeks flowering. I would like to correct this before it gets any worse. Somebody probably knows exactly what this is. Thanks!

Hey for some reason I cannot see the figures in this thread, does anyone know why? I tried with safari and firefox and both will not display the figures in the original post. Any ideas why?

Dead plant! Overnight my best, biggest lady just up and died! I've got 3 plants in half and half coco and soil, and one in a hempy bucket in pure coco and perlite with a pump cycling 3 times a day. The pump fills the bucket up to an overflow ebb and flow action. On week 6 now, and the hydroponic plant was twice the size of the others. The got so tall that I had to rearrange my setup. I covered them all with plastic bags, and broke out the saws-all, and did some cutting on the wooden shelf. I uncovered them, and a little bit of sawdust got on them, and some got into the water/nutrient reservoir. I gave them all a nutrient spray like I do every 3 days at lights out time. They all looked happy and healthy and thriving like hell. The next day, the one in the hydroponic setup was dying or dead. My only attempt to save her was to mist her with plain water and top off the reservoir with plain water. No luck. Every hour she wilts a little more. WTF!! HELP!
At least the other ones in soil are still jamming right along, looking fucking awesome, just now starting to flower.

Please someone help me out ill do anything for some advice at this point soI have figured out what's going on but have no clue how to fix this issue. So basically no matter what I do my ph rises within an hour and stabilizes in or around 6.5! No matter what I do!!!!! I'm using distilled water it has a ph of 7 I then stabilize the ph to 5.6 (where I tech need it to be for now to clear my problem)then I add my nutes and double check the ph and add it to the res and check again once In res. I shit u not within an hour it's stabilized at friggen 6.5 ! I have read online of others having same problem growing in aerogarden bases as a dwc or smaller set ups but they never post the solution and there just using shit aerogarden nutes. I'm using ph perfect sensi line from advanced nutrients and the hobbiest bundle aka big bud, overdrive, ect. So from reading have saw lots of people seeking advice on this issue in dwc systems and all saying it's stabilizing at or very close to 6.5 um deff not random so how do u fix it's not saying!
I have a nutrient lockout going on because my ph is way to high and no matter how much ph down I use it rises and stabilizes at or around 6.5 I know it's not my nutes !!!!!!!! How do I change this and get it to stabilize at a lower ph for longer than a friggen hour or less !!?? My res on the dwc aka aerogarden is about only a gallon and have a air stone in each one running 24/7 and have lights at 24 until bloom and I cut to 12/12 which problems exist in both chambers and conditions! They are in a stealth cabinet with a lower veg chamber and a upper bloom chamber supplying the different spectrum lights needed why is the ph doing this??? Please god help me haha

Importance of rinsing media in an ebb and flow system. I just wanted to share something. I thought I could just keep adding water and nutes to my system without a rinse or flush very often. My plant died! It wilted and keeled over. I saved a couple clones, but lost the mother. When I pulled the air stone up, it was covered in some kind of moss or growth. Everything was going great when I was using a small jug, and changing the water/nutes every day. Then I went to a large bucket, and just added when the level got low. On the third week of that, momma died suddenly, went from thriving to wilted overnight. So, lesson learned, it is extremely important to flush, rinse and change water/nutes at least every other week. Hope no one else has to learn this lesson the hard way like I did. Plain laziness cost me a huge plant. The others right beside it that are in 50/50 soil/coco never missed a beat. They get everything exactly the same as the one I had in an ebb and flow hydro system, except for they get watered/fed every 3 days, because of the soil.

Ok, I learned something else about my last post, about the importance of flush/rinse. My algae problem didn't develop just because I didn't change my water. The main problem, and possibly the only problem was that I let light shine into my reservoir bucket. I had a piece of foil thrown over it, but there were large gaps where my water and air lines went in/out. It HAS to be completely dark in the res. Even a small opening for light to get in will make algae grow.
There really is a lot to learn about hydro systems, and tiny little details can make catastrophic differences. Luckily I had 2 plants growing in good old soil, well half and half with coco for better ph control, and that part is going fantastic! WP_20140126_007.jpg

Hi everyone

These plants are growing in miracle gro moisture control and they are 6 weeks old...they spent the first 5.5 weeks inside under CFL bulbs and are now outside for a few days hardening up before transplanting permanently outdoors in the garden

They have developed some discoloration on the lower leaves as seen in the two photos below and I'm wondering if it's a mild sign of stress from going indoors to outdoors that i should be concerned about or if it's a nutrient deficiency.

Any HELP appreciated :)
