Hear hear!!! haha Hey so im curious if I should add the cal/mag all the way to cut down, or stop adding it at a certain point before chop?

All the way and it's still not gonna be enough for one reason. They both have low solubility and your base saturation is still low. But you can fix it before the next run :)

Hmm ok, so your soil is happy frog or green squirrel or something like that, innit? These soils have their potassium levels typically up the roof... and potassium is a cation (K+), which clings to soil particles with other cations such as calcium and magnesium. But these companies don't have a clue about the importance of ca/mg pair, so they skip it and thus your base saturation is low with majority of cations being hydrogen and potassium. And when you push ca/mg during plant's growth it's gonna have to fight with k/h first in order to get into absorption zone, so plant needs to absorb potassium first. Hydrogen is not absorbed though as plant breaks down water molecules to get it. However it still occupies significant portion of soil particles acidifying it, especially if CEC is low and ca levels are low too. But if your CEC is high and ph is high, then potassium and in commercial mixes phosphorus are biggest players. And you can't just displace them, cause they're light molecules and they're more mobile in soil than ca/mg. Phosphorus is actually quite immobile, but potassium is very mobile, so it'll always win competition for affinity with calcium, which is very heavy and if there's not much of it adsorbed it's gonna take the back seat. So the only way is to minimise potassium levels in soil in favour of ca/mg, but you can only do it before the planting. I hope I explained it well :)

Yes that makes sense. Is there a way to minimize potassium levels in my soil or would i have to switch it up?

You can do two things: switch the soil to low potassium one: ProMix or Sunshine sth, or you can keep recycling the one you're currently using without adding any ferts, but upping saturation base by adding more ca/mg between the runs. Optimally you should have about 20% of soluble calcium and around 2-3% mg in your soil, but not more than 1-2% k. Welcome to #highbrix school :)

I just double checked and it's called Sunshine #4, available in Cali. It's been tested by the lab that Doc Bud uses, so it's legit. Basically you can get to the right proportions etc. yourself, but if you wanna take the easy route, which means spending money, you buy Doc Bud's kit :)

Just FYI!

Thanks bro! I cant wait till the day that im on your level. Btw the plants i have outdoors are the same ones i have indoors and both are about at the same stage. I just borrowed a nice camera from my boss to do a cool post. What would you call the same strain of clone taking from the same mother plant? IS it genotype or phenotype?

And seeing your outdoor plants going through a rough time, but still praying to the sky really stroke a chord in me. I do want to graduate from the #highbrix shcool!!
