Hey guys could anybody tell what is wrong by these pictures?

At the moment it's a single plant out of 4 and the whole top if the main stem all the leaves big and small have started to go like this.

4 plants and only one is showing these signs. And it is purely the top of the plant. Rest of the plant is all green and healthy

Strain, age, medium, and feed schedule would be real helpful. You wouldn't want to follow advice on nothing more than a picture of 1 leaf. There are also several threads with charts showing deficiency on here and the web in general. Where they clone or seeds.
 
Sorry. Strain is Psychosis, growing hydroponic bubble pots. I'm using the Genesis Formula while I do once a week and then just keep topping up with phd water. I've looked at charts and it's hard to describe as th pictures don't show it but the yellow has now started to show a browny/purple colour. I couldn't find much that matched it

If it was soil then I had some idea's but I don't mess with hydro and don't want to mess you up. You could try the 600 Club, there are some real good growers there that love to help.

If I had to guess, it would be some kind of P lock-out.
 
Could anybody possible PLEASE help me with this. I have attached some more pictures. Now I have flushed with ph water, I have 4 plants and this is the only one like it. It started going yellow and then purple at re top. It then spread from the top downwards. Now what's odd is at the moment it is still drinking water just as fast as the other 3, the bud is still beefing up everyday I look and the roots look healthy and there is no smell to suggest root rot. All of the small leaves around the bud areas are a lovely green but the bigger leaves have either turned yellow or gone purple. ANYBODY help me? The only suggestions I've had is it got too cold. But it's in the same environment as the other 3

Anybody help me??? I know I can't cure the leaves but I was hoping to at least identify what it is in the hope I can save it till harvest like 4/5 weeks time

Do you have the Guaranteed Analysis?
That coupled with age is always helpful to me. I still may not be able to help though. I suck with deficiencies.
Are you feeding something with a lot of Molybdenum?

I'm in hydro and that looks like a Phosphorus def to me. I don't know anything about your nutes. I run Dyna Gro and General Hydroponics Flora Series three part. But week 3-5 is right when I'd expect to see that if I was using my growth nutrient instead of my bloom nutrients.
 
Ok phosphorus fits. The only thing I can think is that perhaps the cold spell we have had causes some kind of lock out. In an attempt the fix the issue I flushed it with phd water making the deficiency worse. I guess my question now is will it bounce back? It's awfully yellow/purple. It doesn't looks nice but the buds are showing progress. I have of course put the nutes back in to were they would be normally and will keep my eye on the ec to make sure it is taking them up. Any other recommendations to revive it?? Thanks for your help

This could be your problem what are your PPMs on the reservoir and what does the entire reservoir's pH run? What are res temps too? If you are recirculating nutrient depleted water because the plants are chow hounds you could see this.
 
I don't actually have a res, It's a pain but I do each pot separately! I have a schedule for each week which my brother in law gave to me and I just tweak it when needed. The EC this week was 1.8, usually when it comes to the final day of the week it is usually down to 0.7 which is only slightly higher than normal water in my area!

To be honest it looks like it's a goner, I might the only green left on it now are the small leaves around the bud sites. Virtually every other leaf has gone yellow and purple. It's odd though I would have thought it would stop drinking but it still is!

Lights on is around 25 degrees, off is around 15. The lowest it has been in there is 13 degrees!

Simple senescence! Fall colors but you still need to up the nutrients if you are falling that far down. They are hungry.
