Is this a phosphorus deficiency?

Hell all,

Using megacrop 1-part nutrients in an octopot.
PH is 6.0 and PPM is 960.
Using CO2 that gradually have increased to 1300ppm.

Temp is 90 degree with surface leaf temp at 86.7f and humidity at 58 for proper VPD of 1.2

I had no deficiencies until flipping to flower and based on my experience and research seems likely to be a phosphorus deficiency.

Thoughts?

people have had problems with the stability of the ph of megacrop once it's mixed which could be it. for me, it would drop or raise to the point it caused problems in my medium. when I ran it I would have leaves that would end up like yours so possibly something is up.

Yessir I had to use Epsom salt. The magnesium content of Epsom salt can help plants absorb essential nutrients, such as nitrogen and phosphorus.
