So iven been battling slight phosphorous def through out flower for some time now and am just honing in on the perfect amount of nutes to use and such but its kinda hard when your not growing the same strain each time and all strains have diff nute uptake ratios. But eithr way the phos def have been affecting pretty much each lady in my flower,some worse than others. I heard that someone on here also had phos deficiencies when using great white bc i guess the plant is just uptaking more nutes than usual with that stuff.Can anyone attest for that or have had experience with great white and the deficiency. I attached some pics so hopefully you guys can confirm its def a phos def.The spotting is happening at the very bottom of the plant and usually working its way up the plant somewhat.Im also getting the tell tale signs of a phos def. from the purpling of the fan leaves and petiols.The def seems to be affecting the bottom fan leaves the most working its way from the outside of the fan leaves toward the center veins. A lil background:coco,technaflora lineup.plus i add some flowering bat guano when im preparing the coco and i even sprinkle some on the top of the pots if i start noticing some P def.But it just seems like i cant keep up with the P uptake.
