Lockout?

[Bungo]

Hi guys,

Currently got two different strains of blueberry on the go both on day 60. Both been treated the exact same since seed.

Sat in 5 gal Using Plagtron light soil with advanced nutes bloom a+b as well as overdrive and carboload (following taNgs feed plan) with RO water topped up with tap water to 100ppm. pH'd at 6.4.

over the past few days have gone from one or two lower leaves effected to nearly the whole plant just a few days later! Pics below. I was originally thinking mag and phos deficiency now I'm thinking lockout as it's effected the plant so quickly?

Should I give it a run through of flawless finish?

Problem: brown splotching and dying leaves

Medium/grow method: Soil, plagtron light mix with perlight

Feed: and supplements used: advanced nutrients. Bloom A+B with overdrive and carboload. (tanGs schedule)

water source: RO Water with added hot tap water to raise temp and ppm to around 100 ppm and 22c water temp

Strain/age: Blueberry 420. 62 days.

light used: Spider Farmer SF2000

Climate: Set to 24C and 55% humidity.

Additional info: slurry test came to 6.5 ph but need to calibrate ph pen. Have now flushed the medium with ph'd 6.5 water.

I had a very similar issue. Same exact pattern. I have 6 GG#4, all treated the same, one was showing same exact deficiency/lockout. I bought a blue lab pH meter, checked the soil pH and it was sitting around 5.7pH. My next few feeds, I did 6.8pH and the problem stopped, so I assumed it was a lockout. I hope this helps you out

Fill this out and it'll help those that look in. One of the first things I do with feed issues is get a slurry test done and find what the medium is @ pH wise.

Cheers I'll edit the post now.

Yea I just did a slurry test and ph came to 6.5. Assuming my Ph pen is accurate, need to find my calibration bits...

The purple stems can either be a genetic, or it can point to a Mg deficiency. Your pretty far along, don't know that I'd be wanting to add more nitrogen to the party, maybe a little epsom.
