What the fcuk1!!!!

I have no clue what happened plants were so green then this showed up. any solutions ph currently reading 6.5

Looks like a P deficiency, are the leaves on the bottom of the plant browning on the edges and the tips pointing down.

Looks like u might want to raise ur pH just a bit to get full access to P.
