Thanks for the tag and compliment. @1HappyPappy has you covered, I would also like to add, General Hyponic PH Up and Down are your best friend. While there are additives that will work in a pinch, they are by no means suitable for long term usage.
What does your system look like? ( pic’s?)
What nutes are you using?
What pH meter are you using?
What lights do you have?
What are the water temps?
So I have only actually used baking soda 2 times waiting on my ph up to come in the mail. So I really cant say how much to use but if ya add a little bit at a time you should be ok.
Do you have anything to get ph down if needed?
Lemon juice or vinegar can be used, basically anything that is very acidic…
I feel I should say you may want to pickup some actual ph up and down.
If you was in soil I fill like it wouldn’t mater at all.
But for simplicity and consistency, i think the up and down is awesome but the other things will work if its what you got…
But @HappyHydroGrower definitely has you covered
I reach out to them if i have questions as I’m just in my first year of hydroponics
Thanks for the tag @The_Chef … @Cooterhog welcome. Yes some pics please. And ph up and down a definite must. Gonna find alot of info and different techniques here. You will certainly find your answers. As @HappyHydroGrower stated, good lcuk and happy growing.
I thought it would be done 1st week of June but because I didn’t understand ppm it will be later. Here is current pic: (any help or advice I will GLADLY take) week 8.
One comment on baking soda and TDS: baking soda will load your nutrient solution with salts and jump the TDS up quite a bit. This is something to be careful off because you have to provide solution at a specific concentration and adding b.s. can cause nutrient burn. It also tends to clog the stomata of the leaves if sprayed on for mildew protection. PH up is really your best bet.
This late in flower it’s probably not going to stretch anymore just the buds grow taller. And for an Auto you are probably finishing up and another few weeks
