Sun was the beginning of week 6. Random leaves have been yellowing for over a week. At first I thought the soil was too dry (it was) got it good using only water. That didn't seem to change anything. Tests said ph was 6-7, N was low, P&K were high. I added general purpose miracle grow. ..no change. I've only been using the foxfarm trio, compost tea (twice), some calmag and molasses since beginning of flowering. Trying to be as organic as possible. Could this be root bound? Lack of co2? Do I need to transplant to a bed instead of pots? Can't figure it out and I'm pretty worried about losing them. I've been using water from a dehumidifier reservoir. Thanks20131111_205607.jpg20131111_205558.jpg20131111_205544.jpg

I could be wrong but it looks like they are just nearing the end of flowern other wise you could add some N but that will only be a quick fix.

Nah it looks grand fella....expect that yellowing and dying off of leaves in flowering.

Expect it if you use "bloom" fertilizers with little N and to much P and K, like pot forums would falsely have you believe is correct. Adding an all purpose fert is a good idea but don't expect it to change much with the leaves that are already yellow. Look to the new growth to see if there is any improvement.

This early though? The buds don't seem to be progressing much, if any. This is my first grow, I'm not familiar with the flowering process. I've been mostly going"by the book" on nutes, lights, etc. The first 4weeks were great growth, looks, and smell. Not so much lately. I'm really counting on this harvest. I have a lot of time and money invested in the setup.

I've figured that out, that N is still needed. I only used big bloom once a few weeks ago. When I took soil for the tests, roots and feelers seemed to be thriving, so I feel like the dirt and roots are good. So you think give a few days before making any drastic changes like transplanting? What do you think of the water supply? It seems to me that water from the air (from the dehumidifier) would be about as pure as possible.

1. How do you know that N was low and P and K were high? What kind of testing instrument do you have that tells you that?
2. What PPM/TDS are you feeding at?
3. Why are the plants in the back of the tent not showing the same signs of issues like the other plants? What did you do different with those plants?
4. What brand grow tent are you using? There have been re-calls on some tents because they emit a gas that poisons plants.
5. What growing medium are you using?

If you don't have a ppm/tds meter get one asap. No one should grow with out one and a ph meter.

Plant on the Right looks normal, fan leaves taking a death dive, the other leaves are still green nice bud growth.
Plant in the Center looks a little worse. it could be alot of things making it look worse, hard to say.
Plant an the left has some serious issues. maybe (N) def. or something else to make it pale like that, all the leaves are pale, they shouldn't be.

Some new pics, plants are not in the same position though. I believe adding N helped, buds have gotten healthier and I can see new leaves at the budsites, even on the left one. To answer some questions;
All were treated 100% equally (weird huh?)
I built my grow room (pretty proud of it)
The soil test kit is in the pic (got it at Lowes)
The kids in the front used to be in the back (moved for easier care)
I don't have a ppm meter yet
Medium is a mixture of potting mix, organic compost, and dirt

Ya get yourself a ppm meter as soon as possible. Even if you use a complete fertilizer you still have no idea what ppm you are feeding your plants at and with mj they need good dosages of n/p/k especially at the stage they are at now. You could be keeping your plants from growing and yielding to their full potential.
By the looks of the flower formation they look hungry for nute's but if you are not knowing what ppm you are feeding them at it's too hard to give you any more accurate advice.
