Critical Purple Auto (GCS)

Well I'm still working with an unidentified nutrient deficiency. Someone suggested iron as I have green veins and yellowing leaves. One leaf on the older plant is turning white. I have added cal-mag-iron with every watering now and have been applying it as a foliar spray as well. I'm also wondering about nitrogen deficiency if they are heavy feeders or phosphorous deficiency since this started when flowering started and I do have red/purple stems. Who the hell knows. This coming week I will be switching to full bloom nutes and will continue the foliar spraying daily at minimum. I think the lime green-ness has improved over the last several days, but we shall see. I have also decided to make seeds from these ladies if they will be healthy enough to do so. I don't want to spend more money on seeds when this grow isn't going too well right now. I have more to learn! What I will say is that I think the repotting helped these ladies to get the clue to start flowering, though! We will see what the next week brings. I hope they darken up! Wish me luck, I need it! I also wanted to note that I did notice that new growth was coming in lime green and I learned THAT IS NOT NORMAL which also makes me suspect an iron issue. I just hope it can be fixed.
