I can't figure it out.

What's wrong with my plants?

Phosphorous deficiency?

Soil PH: ~7.1-7.2
Water PH: 7.5-8

Last feeding given: Fox Farm Beastie Bloomz (0-50-30) @ ~530ppm (trying to fix phosphorous deficiency)

I just can't figure it out, please help my babies

Also keep in mind these plants sprouted December 12th and seem very small to me. Last picture shows some leaves I culled earlier today

Your ph is possibly a touch high if your measurements are accurate. Google ph lockout chart to see what I mean.

Your correction was probably a mistake. Plants that small require little nutrients to begin with. Going with such a crazy high amount of phosphorous and potassium will also cause nutrient lockout. Google nutrient antagonism charts or mulders charts to see how much stuff you can throw off by going too high on those two.

According to the PH lockout chart I could only possibly be locking out manganese or iron with a ph greater than 6.5, does that look like either to you? What would you recommend I do? I have ph down..balance some water to 6.5 and flush?

Since your getting well over 7 ph, I would ph down some water to 6.0 and flush until the runoff was around 6.5.

Looks like nutrient burn. That 0-50-30 mono potassium phosphate is some potent shit. 530 ppm is way more than I feed my mother plants. I'm on the .5 conversion scale. Are you in soil or a soilless medium?

I can't figure it out.
