Why green bleeding not red or blue a hardware independent rgb colour controlling from the IEC hub 75 cable from stm to panels r1 g1 b1 r2 g2 b2 aka r0 b0 g0 r1 g1 b1 6 x v resister pods and all linked to gnd

Green led work on lover voltage then red and blue, so its bleed first.

As i understand bleeding problem is in off state. In off its still have some voltage (not enough for red and blue) but enough for green.

Look on the forum, Putting fets with resistors on ground solve problem.

Did that changed all my colours from red to yellow maybe changing the capacitors value may work as i removed all my capictors and did a test and  one row went yellow in one spot on my p4 but in duel it also changed  the other p3 without the capacitors  and i got new panels with no mosfet snd still the same issue i checked gnd i changed  data  cables i think diodes  going on series or parallel dont know if this would work with pwm  

Series. Circuit hub75 output from shield

Stm32 out diode on red to rgb x2 input hub 75

Stm32 out diode to  green rgb 2 input hub 75

Stm32 out diode to blue rgb x2 input hub 75

Or

Paralllel CIrcuit hub 75 output from shield

From stm shield output  Pin 1 diode then outpin 1 to panel input

From stm shield output pin2 diode then outpin 2 to panel input

From stm shield output Pin 3 diode then outpin 3 to panel input

Miss pin 4 as its gnd

From stm shield  output Pin 5 diode then outpin 5 to panel input

From stm shield output  Pin 6 diode then outpin 6 to panel input

From stm shield output pin 7 diode then output 7 to panel input

A verible resister also on 1 gnd pin across each rgb changes the colour brightness aswell instead of software driven pwm aswell

I did try this and it seem to work ok lucky 1 said about shift registers but it seem there.should be 6 pods for each rgb input to change colours

Thanks

P2.5 with pod no green led seem to clear we need really need  two  pods across go and g1 out from stm discovery to panels

 And end pin to any of the tired Gnd
