Can anyone help me figure out what's wrong with my plants?

I'm currently running a flood drain system, feeding them flora grow. Room temp 77, 62.1 Rh, water ph 6.0. Still in vegetation.

Looks like a phosphorus deficiency

Phosphorous deficiency symptoms include; red stems and slow, stunted, or deformed growth but also include darker green lower leaves as well as leaves that may yellow then die. Adding an organic fertilizer containing Phosphorous can fix this problem but, while improvement to damaged areas may not show, newer growth will appear normal.

Flora Gro or FloraNova Grow?
I believe it looks like a 'P' deficiency along with PH problems.

Usually I find it is PH related... If you are feeding it the right plan to cover all the needs and it looks deficient check the PH..

Flush those blocks and feed it good PH'd balanced feed...
