Hello all, I am a frequent reader here at Grasscity forums, lov the family and wealth of information. Learn a lot. I have a question hoping a member may be able to help with. I believe I have a Potassium deficiency and am asking for some help figuring this thing out, not my first rodeo with this issue, just unresolved. Old lady here willing to learn a trick or two. Soil- PH balanced soil, worm castings, and Potters gold, and perlite. Outside grow. Nectar of the Gods line, Spartan regimen. Plants have always been hungry, finally PPMs are rising currently at 300, slurry test 7 Ph. I am feeding feeding and feeding, then rain washes the spider out. Problem, large fan leaves yellowing. Usually lower to mid-rise up the plants. Every plant also using brewed tea, worm casting and molasses. Heading into Late veg, just starting late veg nutrients. Floating some photo's your way, hopefully getting this licked, as it is concerning to me and is driving me nuts! I appreciate you taking a gander.
with some strains its normal for the fans to fade heading to flower IMO test it out and add 1/4tsp of (N) nute and warm water, to a pint spray bottle and spray a fading fan 2-3 times a day it may show in 3-4 days by greening up this would proove something wrong in the root zone and check the ph of your rootzone soil too good luck
