This is where alkalinity and fertilizers used come into play.
Here's a little bit more of the conversation if you're interested, useful stuff if you're growing in ProMix:
"___ think of PRO-MIX as a filter. It can filter out elements from the water, but it cannot filter out pH. As elements, such as bicarbonates, nitrates and other elements accumulate in the growing medium, they start to change the pH of the growing medium. The buffering capacity of PRO-MIX does not change overtime, but the exchange sites can be loaded with new elements that can change the pH of the product. Again the exchange sites (or cation exchange) is much lower by volume compared to soil, so the pH of PRO-MIX can be changed within a few weeks after planting. I would not look at the buffering capacity of the PRO-MIX to be significant.
The fertilizer used has to have a neutral effect on the pH of the growing medium. In commercial horticulture this would mean that the potential acidity or potential basicity of the fertilizer should be near zero. If it is much above this value, then it will cause the pH to change. For example, if the fertilizer has a potential basicity above 50 lbs calcium carbonate equivalent , the pH of the PRO-MIX will go up over time. If the fertilizer has a potential acidity higher than 100 lbs calcium carbonate equivalent, then the pH will decline over time."
Never had an issue following their advice in the years i've used ProMix and have had MANY successful grows. Misleading their customers is HIGHLY doubtful..I’d stay away from them for learning stuff
LOL.. I doubt anyone WANTS to filter their water but it's reality for some of us blessed with shitty water.also, I doubt most people growing cannabis, do or want to filter their water.
I have shit water but I’m not about to send a few gallons down the drain (anymore), to get a gallon of less shit water. People do drink it still I think lol and the plants are okay so long as I pH it, hard to call anything organic using it though which is pretty sad.LOL.. I doubt anyone WANTS to filter their water but it's reality for some of us blessed with shitty water.
Dr Bugbee also founded Apogee Instruments.. Should we now question his advice as well?
I like how they talk about gypsum as if it’s a pH up. It is a great pH down has nickel in it which I hear is also good and usually lacking but should look into more. Cheap, organicNever had an issue following their advice in the years i've used ProMix and have had MANY successful grows. Misleading their customers is HIGHLY doubtful..
"In conclusion, Epsom salt has little influence on the pH of growing media. It is simply applied as a fertilizer supplement to provide additional magnesium and sulfate missing from the water and fertilizer."
"In conclusion, gypsum, under most circumstances, has little influence on the pH of growing media. If there is a need to increase the pH of a growing medium prior to planting, incorporate limestone, which contains the carbonate ion that actually causes the pH of growing media to rise."
I don't think you'll find many people arguing with their conclusions. Advising people to use mag sulfate or gypsum to alter the pH of their growing medium is dubious at best.
Maybe its just me, but I notice some improvement from the first set of pics. Definitely not deteriorating further. Hang in thereThis is how they are looking today. I removed all dead foliage and watered them yesterday with a full strength solution of FloraGro Series, with a touch of Pi Nutrients Super Root.
I lightly foliar fed them this morning with a mist, in the hopes they absorb some nutes this way before the watering nutes get carried up into the plant.
Still not very happy looking plants.

New growth? It doesn't appear there is any still. I removed all yellowing leaves before i feed it full nutes, and now more leaves are turning yellow and still burning tips. The plant is still basically consuming itself from the edges of the leaves inward.Definitely looks like an improvement. How does the new growth look? Keep in mind the damaged leaves are never going to look good again.
The kind or pro version of botaniocare?i grow with pro mix hp with botanicare liquid nutes and never ph, ppm, ec anything, no clue what it is, no clue what’s in my tap water,
never water to run off..
never a problem…
just saying..
if synthetic nutrients are used than you have to ph etc..
Maybe a tiny bit eh, just comparing the pictures myself. Still no new growth really tho and still leaf yellowing, but they do look a bit perkier.How about the media itself? are they drinking ANY water? They do look like they perked up a bit. What EC did you feed them last?
is that the distance the light has been the whole time?It might just be that they were basically in RH shock im really suspecting now. Surprised they are still alive really lol.
They did start off all nice tho, but pictures show they had a proper RH then too... they look nothing like the larger plant in this pic tho, even tho same grow medium, same feed schedules depending on stage, and same ph adjustments

Yes installed once never moved again, i just adjusted brightness depending what they wanted. Light puts out alot thois that the distance the light has been the whole time?
