  1. Ok so my plants are outdoors and have been in flower for about 3 weeks. A few of them just suddenly started to turn real yellow so i gave them some ferts i have been using fox farm big bloom and also tiger bloom. so when i went to check on them yesterday i noticed that the ones that were yellow are now like yellow with puple on the leaves. I understand this is probably nitrogen def or lockout but i want to know if there is anything that i can do to get these girls green again. they still need another 4 weeks but going how they are now i am wondering if they will even make it. And another question some of them have gotten a very dark purple color to the leaves, which is also some sort of (def) not sure what tho. Thanks:smoke:
  2. when you say they are outdoors Im going to assume they are in the ground

    the best course of action would be to poke down as deep as you can at the base of the plant for a soil sample, the deeper the more accurate the PH reading

    the purpling can infact be due to a PH issue but if the nite time temps are around 58F this also can account for purpling

    mix the soil sample with a small amount of 6.5 ph water to make a slurry, test the PH of this slurry

    optimum soil PH 6.5-6.8 you may need to flush
