Morning dude,
I havn't personally used these specific methods for testing, so im not very familiar with them.
I've always done the liquid, then add the powder method.
But i think i can make sense of it.
It looks like N, and P are off the charts on the NPK test?
Potassium is in the deficiency range?
Potassium plays, a pretty important role too. Quite similar to calcium in a way.
Edit: yep looks low in K on both tests.
I personally don't believe the second test's read of being deficient in phosphorus. I think it is being locked up, so the test doesn't read it.
I reckon Gypsum should be ok.
The colour of the ph sample is hard for me to distinguish. But i'll take your word on 6.5 to 7.
My own personal way of moving forward, would be to top dress with gypsum. I would also add a little potash, to try and balance the NPK out a little. I've always used my wood ashings for potash. But you can buy the store bought stuff. It's strong though.
I'd give it a week or two, and see how they respond. Depending a week or two down the road, i might add a tiny amount of nitrogen. I would use blood and bone meal. I'd give it some mulch too.
A couple weeks further down the road, if the ph hasn't come down a tad, i'd give a light feeding of liquid sulphur.
I did some reading about blossom end rot as well. Apparently once the tops have started rotting its too late, and it's best to chop the affected areas off. So the plant can focus it's energy on recovery, instead of repair.
I would wait a week or two before making this decision though. You want to feel comfortable what you have done is helping the plant, and the problem isn't spreading, but staying fairly localized.
Best of luck. Hope it helps.
Anything else creeps up, make sure you update.
All the best.
