I think it is an everything deficiency. What nutes are you using? The bright yellow is usually an N problem that can happen at the end of a grow. How many weeks since the flip?
 
Its an auto plant with 2-3 weeks left, thanks rose!
 
This must of been one hungry lady.. her 4 room mates had some nute burn.. so I gave them all a flush, and was going to continue nutes next feed. This young lady didn't take too kindly to it.. I believe you are correct with your diagnoses. Thanks again
 
Any time you flush the medium, you need to reintroduce nutrients before too long so that they don't get hungry as the plants at this point are at the height of their metabolism and are needing access to food almost daily. I personally don't agree with allowing the medium a drying period after flushing. I will go right back after flushing with new nute solution that is well aerated and pH adjusted. The aerated solution will take the place of the drying period which is to allow the roots to breathe.

That plant surely has a lot more than 2-3 weeks to go.

Are you sure the other plants had nute burn and not a deficiency of some kind. What and how much have you been feeding them?

Even with a little nute burn, I do not flush my plants. I only flush for very severe problems.
 
Jan 16th, mixed up nute solution at 12am, 10L old tap, 10L R/o - PH(7.4)

+0.75ml/L micro blast = 15ml
+5ml/L Grow = 100ml
+2ml/L Bloom = 40ml
+2ml/L Xatalyst = 40ml
+12.5ml MycoMadness

+.75ml/L micro = 20ml
+3.5ml/L Grow = 90ml
+3.5ml/L Bloom = 90ml
+1ml/L Meta-K = 25ml
+1.5ml/L Xatalyst = 40ml

After upping the dosages it wasn't fixing the problem so I went with the flush..
 
Hey Hush,
Yes I should of re-introduced a normal feed regime after I did the flush, especially considering with the extra perlite in the pro-mix, the plants didn't seem to notice when I flushed them. No droop, or anything..

They were thirsty only 2-3 days after the flush which was abnormal, (they usually go 6-7days) they drank alot more with the weaker nutes

The kicker to all of this, is that some plants are very happy, while others like this one are trying to die on me.

I gave all my plants the same nutrients, but they are not all the same strains.. perhaps that was a major error on my part.

These auto's mature pretty quick. I was getting burned tips on all of the plants, and this one was heading downhill, I up'd the nutes that didn't help, so I tried for a flush. Here is a quick updated pic, seems to still be putting on weight..

:laugh::yeahthat:
when you feed your plants, they will require quite some time to show any signs of improvement, and in their current state, i think that the best that you can hope for is that they stop deteriorating...
 
Yeah unfortunately, when plants get deep in flower, they quit concerning themselves about anything but the flowers. Most of the time they will not heal themselves after damage has occurred. They will instead, take the nutrients from the damaged areas and then drop those leaves rather than reroute any resources to the damaged areas. This is even worse with autos because off the nature of how they function. That is what makes them sooo finicky. They can do really well or crash really fast, there is little to no inbetween. The key, as Zem said, is to stop any further deterioration so that the plants can ffinish.
 
Not such a bad thing, the plant trying its best to make some bud.. These auto's sure are finicky.. things can go from good to bad to ugly in a week.
 
So next time no auto seeds. I bet you would rock some fem seeds. Autos are finicky fo sho
 
not too sure, its in the low 8's out of the tap
 
Ph needs to come down to 5.6-6.6, you're experiencing serious lockout with your ph so high.
 
plant had run-off of low 6's, not sure where u see it having high ph unless your diagnosing from the pictures

The 7.4 PH reading was from mixing 50/50 ro and tap water
 
7.4 PH is too high bro. Listen to lifespan 5.6-6.6 before you pour it onto the plant. It's your super high PH
