First let me mention the details of my grow and then I will explain what is happening and hopefully get some help on this issue
Stage: was on 14/10 for a few days and yesterday switched to 12/12
Medium: bottom half of 5gal pot has roots organic soil with 1/3-1/2 dose of organicare pure bloom composted poultry and 3grams of dr. Earth 4-4-4 that I transplanted into like 3weeks ago, top half around 1gal transplant is plain roots that's been watered about twice with botanicare pure blend bloom compost.
Water: well water near lake that's around 200ppms that I always ph with earth juice down between 6-6.5
lights: phantom 600s with sunpulse 3k and 4k bulbs
strains: sensi seeds super skunk, landrace afghan kush, Dutch passion orange bud and strawberry cough
So I've been battling mild case of fungus gnats, and started getting what looks to me to be phos deficency. Started more towards bottom and on some central and few top leaves. They are yellowig slightly at edges with slight brown edges and tips, looks like ph issue and phos def picture in Ed rosenthals book. Before this happened my plants got dark dark green then I pre sprayed with mighty wash before flower and used power wash which removed nearl 90% of MW. Then leaves got light green then saw slight cal def then yellowing and what I first thought was disease but now think is phosphorous def. only other things I've used few times was nematodes, roots oregonism, and other tomatoe which is Humic acid, b vitamins, bacteria like bacillus subtillis, molasses, and stuff to increase photosynthesis and fight diseases
Since mighty wash and power wash spray leaves have gotten back darker green color
