Where abouts on the plant are the leaves yellowing like that?
If it's from the bottom then I would agree with Maj.Cottonmouth.
There actually showing more of the yellow towards the top fan leaves.... I upped them to around 1000PPM.. and yes my tap comes out around 150PPM.
Getting a blue lab guardian monitor in tomorrow so I will most likely do a whole rez change out and go with 7G a gallon...
your going to love the guardian man.
so much easier to walk into the room and know whats up at a glance rather than bending down opening res top, and checking with a hand meter
its expensive but its money well spent
Sorry man I assumed those were lower leaves you were showing in the pic. If it is upper leaves yellowing I would think you are experiencing a lockout. What is the pH of your res?
///EDIT/// Sorry, went back and read you keep it at 6.3-6.5, I run much lower (5.6-5.9) but I am in coco and treat it like hydro. With soil I think you want bump you high end up to 6.7 or 6.8, per the chart below you would be starting to cut out P, Ca and Ma if you don't go above 6.5.

Me too.
I've heard it through the grapevine, that perhaps that's why we depend on the micro-herds. They break-down the component nutrients, minerals, metals and salts, to a usable form the plants can uptake. (over-simplified, and perhaps over-generalized, but I'm a simple guy...generally)
MaxiBloom can be rough on some plants, (usually my sativa dominates) especially here in the heat of the desert. Since I mix different nutrients to different needs, (dilution strengths) I prefer the flexibility of the KoolBlom as an additive to my Tiger Bloom, so far. And a dash of unsulfered molasses. (carbs, iron, mag, calcium...) Molasses can take the place of CalMag Plus and any carbo-load product(s) one may use. I use less molasses and Tiger Bloom when using the KoolBloom, or I use less KoolBloom and Tiger Bloom because of the molasses. However you look at it, it's working pretty good, lol.

The bigger buds are Haze x Skunk, (2 weeks from harvest) tall ones are White Widow, (3.5 weeks into flower) the others are PokerFace. (3 weeks into flower for most)
Everything through the soil, never a foliar feeding, Fox Farms nutes, (about half-dose) KoolBloom additive, molasses. Keepin it simple, lol. (sort of)
Imo, it's not so much the Sat dom strain but the desert heat.
Ahhhh... what a pleasure to have read all of this thread hats off
I got the maxigrow, maxibloom and dry koolbloom, but i wonder about the liquid koolbloom, i dont have it and wonder if i sould get it? Is it important to use it, what's it intended to do to the plant?
