It seems to me (and I've been practicing this, to great success), that you want to vary your PH. I use coco, so I'll feed it 5.8 usually for nutrients, but on occasion I'll go 5.5 or 6.3. When I flush (every 3-4 feedings) I'll give it 6.3-Straight-Tap. Coco buffers PH well, so I don't want to get a lot of Ph-Down stuck in my soil, affecting future feedings. I had another pertinent anecdote for this reply, but alcohol made me forget it.

One more outlandish idea that I agree with is my own hypothesis that if you have plants with very healthy/dense root masses, then having 'hot-spots' is beneficial... certain nutrients absorb more readily under certain acidic climates, so having spots which each are specialized in absorbing different nutrients might be the healthiest future for the plant

edit: DON'T OVER FEED!!! USE 1/3 OF RECOMMENDED DOSAGE TO BEGIN WITH, RAMP UP TO 1/2 THEN 2/3! YOU WILL DEFINITELY LEARN WHAT"S NEEDED MUCH EARLIER THAN TRYING TO OVERFEED YOUR PLANTS!

Awesome, thanks for the chart and info. I'm starting to get a better understanding about ph and not just knowing about it... I'm one of those people that believe people can know a lot of shit but understanding it is the key to knowledge. I am still a little in the dark on ph of your soil rather than of my water. I think the ocean forest I'm in is like 6.5 out of the bag or something but my brain leads me to think that after 3 months and nutes and all that your soil goes through that the soil would have ph changes. Is there a reliable way to test my soils ph and if so would I do better off adjusting my water ph to compliment my soil ph? Like if soil is at 7 instead of 6.5 should I be lowering my water to maybe 6 or so to try and maintain a 6.5 between the soil and water? I'm pretty stoned right now so if this post is dumb or makes no sense due to wording and rambling on I apologize in advance :)

Can we get a farm consensus on best pH for promix?

Thanks again TK. I've been having some issues with soil. God knows, I need to get back to hydro, but your totally right. PH, is one of the major things you need to watch all the time. Since you posted that chart. I've even been testing the run of from the soil and that right there has answered some questions.

My meter took a dump and I was getting a false reading. I broke out the old trusted drops and BAM!!! My PH was "Way" to low, so I made my adjustments to my PH and to my meter. The best way to adjust a broken shitty ph meter is with a 22oz Fat Max framing hammer. It works every time.

Thanks again and I'll be keeping a closer eye on my ph. Both with a new meter and the droplets.
take care,
BG
Is your finished product better with soil or hydro?

Not been following this thread but just stumbled on this at the right time. Many Thanks Texas Kid :-)

I grow in Organic soil and have only been checking the ph before I add the nutes so I'll be more stringent in future, cheers folks.
that chart is very helpful for sure but i think all strains have a specific ph that they thrive best in you just gotta find it. thanks for the chart very helpful on the soil part.
what medium should I use with Kind Soil?

Spot on I've been told the same thing, swing your ph to give access to different nutes!

Would disagree with the part about not overfeeding. What people need to understand is that the recommended dosage is called recommended for a reason. Like people, each individual plant has its individual limits. I was taught to start off at half or whatever of the recommended dose, then keep increasing and increasing until you see the plant has had enough. It may be that your plant can take double the recommended dose. When you see signs of overfeeding, wind down the dosage a little and ride with that. IMO

I've been growing organic in soil for years with great success and the only time I adjust the ph is when I flush them with water adjusted to 6.0 for the last 2 weeks. During bloom I use either Bio Canna or Bio Bizz nutes or else some homemade guano teas. I always thought organic nutes self regulated themselves,ph wise, maybe if somebody knows better then they can let me know.
I thought a ph meter couldn't measure organic nutes with good accuracy, so instead of adding lots of ph up or down I just fed my plants the nutrient mix without adjusting it and my yields from it are nearly on par with my nft system, where the ph is constantly monitored.

Growing also with Biobizz but my Ph falling down to 5.9 after i put biobizz nutes in... That was my problem and I running in a huge lockout because the Ph is to low so I Ph my water know every time to 6.0 vege and later to 6.8..

how important is oh for soil brands that say you dont have to worry about it?
I know I’m ringing in a little late here, just joining the place, but I think ph is important to know in every grow. If u don’t kno ur ph, then U don’t kno ur problems....but by all means....if u have no problems...u need not worry about ur ph

With soil they say not to usually worry about it cause they have a bunch of Lime in them to buffer. You still want to be in a certain range.

That’s the first time I’ve ever heard that...but we are a little behind times up in Alaska I guess. I guess I’ve just been taught to do it and so I do. But anytime I’ve had an issue w my plants, I’d check the ph, it would normally be high, 7-7.6...adjust with fish hydrolosite, and they get right back into step within 3-4 days. It’s simple science tho, if a plant will strive at its best at a certain ph range (5.8-6.5 for cannabis), why not at least try it and see if it helps? But like I noted before...if u have never had an issue with ur babies, u probly have never worried about the ph, and in that case I tip my hat to u Anytime it’s an easy process, we humans seem to really enjoy it .

Thank you for this! Its a nice reference. I play around with my girls ph quite a bit so that they can absorb different nutes better at different ph levels.
