These are outdoor plants that are in 80 gallons of promix/composted sheep’s manure . I have been supplementing with 250-300 ppm of jacks citrus . As my plants stopped the stretch started to flower I seemed to have an issue with overly dark leaves and what I thought was lockout. So flushed twice with plain water and enough molasses to drop ph to 6.5. Now my lower foliage is still dark green but my upper parts of plans are getting discoloured. I’m thinking phosphorus deficiency. What do you think
Deficiency/lockout?

Could you be treading into the K, Zn, Fe deficiency realm?
Are these 3 usually deficient together?

Not sure. Try a Fe and Zn additive.

Looks like she needs Phosphorus and Potassium for those flowers..

I was thinking fe also. Make sure you micro nutrients are in order. Adding some beneficial bacteria helps to even this out in my grows.... but I suspect a micro deficiency.....then I looked up jacks.
Did you know?
In flower plant will use nitrogen. Duh right
But the plant will assimilate this before the P and K.
20-10-20 is jacks mix that you are useing for flower.
If you didn't add more p or a p/kboost(which I wouldn't with that k) you might be getting a p deficiency.
Think of the as it can do 100 percent of something. Npk
If that something is 40 percent of your food (nitrogen)in flower, and your plant wants that more than the 20percent phosphorus so it doesn't use much p at all.
This is why I try to drop as much nitrogen in flower that I can. If it's not yellow, it's got enough.

High nitrogen and low phosphorus because it’s for citrus crops. Agree a P/K boost and consider buying some GH FloraNova. One jug. That’s it. Works great.

I use GH micro and protekt Silicon @ 1/2 tsp per every gallon and never have issues.
I also run 1 tsp of calmag per every gallon. And 1/8th of a tsp of growers recharge.
That's for water cycle.
For food cycle I just add GH maxi bloom @ 1 gram per gallon to the water mix.
I can run just about anything on this.
It covers all deficiencies. I've run this for 2 years now. Testing it on evrything I can.
So if I need 5 gallons water mix and 5 gal food mix....
I just make 10 gallons of water mix,then add the 5 grams of maxibloom for the food mix. Very easy. I use this from 2 weeks old thru flower. If everyone new about this, the industry would break. No ramping up nutes or PK boost. Just simple inputs, maximum return.
