best to try to add it to soil before planting IMO having medium right from the go is key

That's true. But it doesn't hurt to add more later in the grow. You just top dress it.

oh yea by all means i was just saying since op said he had same prob in 3 crops i was just suggesting a rethink of the starting medium

Personally id say its not a ph issues but something else. Alot of people don't even check ph in soil grows. I only check when I add something to the water.
There's no need to check run off in soil. It just makes people more confused and try and fix a perceived problem and just cause more problems.

i totally agree i personally like the old as time method of soil and i dont often check ph in soil but always ph my water and ive had more than favorable results with this
I did the same way before, just check ph of nutrient.since i have problem few crops and start to check run off. I don't know what is the problem, and guess that's soil Ph issue. By the way, my RH around 35%, does it harm the plant seriuously,likr stop grow,yellowing and crispy dry leaves

Too close to ur light source it sounds. Dry crispy leaves. What are you using for a light. Have you grown without issues for a full harvest before now?

TOO MUCH Dolomite!
Run off is NOT the pH of the soil and is NOT a quality way to figure out soil pH!
Sounds like your over feeding.
RH of 35% is too low......Remember that when your RH is low - the plant will transpire more to compensate so it won't dry out. That means it is now up-taking MORE moisture and that means MORE nutrients are going in too......
I'll bet you start your "bloom" nutrient to soon also!
Pics say more then words and pics of the plant - not a couple of leaves you took off.
List the exact soil
list your nutrients and supplements - ALL OF THEM!
How much do you use at a feeding? veg and bloom
How often do you feed?
What water?
Give us these answers and we can figure this out.

Promix is peat based so you want to ph around 5.8 - 6.2.
1 tablespoon of fine dolomite lime per gallon should be fine.

So then are we using it as a media for a hydro style grow? That's what your pH is saying DG.

So just hand watering one should pH to 6.5 in Promix is what you are saying?

We don't KNOW what ProMix it is for one. The op says "Pro Mix soil". Pro mix now makes fully blended soils for a multitude of applications, not just the old BX, HP and MP!
I asked for the exact soil in my question post.
So if he has one of the new complete soils like the "Premium Organic Container Mix", then YES, he could simply pH to an accepted soil value for veg or bloom and forget about the soils pH.....
I understand what you are doing - but we don't know the type of Pro-Mix it is yet....
Here you all go. Check out the new Pro-Mix soils and lawn care products......Be nice if they can take a bite out of fucking "Scotts" market share!

I hope I will have the time to try some of these products - all things considered right now.
Never have issue before, just last 6 months the problem could not be solve. Light is not close,cause i put 15" away, just it's an old lamp.will it cause by overdue lamp
Give you all information with pictures soon..thank you for your rwply

Yep, managed to overlook that as soon as I hear promix I think soil less. What is the reason for raising the pH during bloom is it to make certain nutrients more available to the plant?

Get some good quality soil, and don't be a motherflusher.....

Yes exactly!
Marijuana grows best like this.
In veg your getting less availability of P, S, Ca and Mg. P being the more important "less" here. You are also making Fe and Mn more available with an in-going pH of 6.5 - Now don't get me wrong here on "less availability"! The plant is getting what it "needs" for the growth in veg.
As the plant rolls out of the stretch, it will self "adjust" the soils (living organic soils) pH up a few tenths of a point to increase availability of P, Ca and Mg along with S is increased and the Fe and Mn are decreased.
This is how nature works for our plant in living soils.
Sadly the use of synthetics robs the plant of this "natural" shift for the most part. By increasing your in-going liquids pH, these cpl of tenths. You "help" it make the slight shift and you will see better results.
At least in my book I feel I got more stable blooming plants that produced better when I used synthetics.
Organic soil users/feeders don't need to do it as the symbiotic relationship between the plant and the soil, self adjusts like I said above.....
COOL EH?
