Cool mate, I'm liking the sound of this. Soz for being a pest last few days haha. Cheers. IUnnecessary trips up n down stairs with 30ltr of water lol.
Lol happy to help man. Lugging water sucks. I use a pythons cause I'm lazy. Hell on my coco I have autofeed on a table that drains into a container then a condensate pump in it that pumps it down my drain lol... I fill my autofeed res with the python.

🤣 nice one lol, cheers tho appreciate it.
 
Good idea to test the runoff and see how the ppm and ph are if you still have it. You can how well it's correcting and the stability of the root zone

Forgot to say about runoff, ph is 6.7, 106ppm and ec of 2.23

Hmmm something is wrong with those numbers on the ppm EC.

PH is to high for coco.

Have to read back as I have some questions but wanna see if you already answered them
 
Tap water,
37ppm.
Ec 0.08
Ok what are you adding to it? Think you have an alkalinity issue. Have a read here but you almost certainly need to add a buffer to that water to stabilize the ph.

I bought phosphoric acid for ph down.

I use sodium carbonate for ph up.

Yeah but you likely have low buffering capacity and that will create an unstable ph and large ph swings.

Cannabis can tolerate a fair bit but does better in a more stable environment.
 
I'll use bicarbonate of soda till I get ph up. U think it'll have damaged them
Baking soda is the same sodium bicarbonate. Don't use that either.

You need something like calcium carbonate, potassium bicarbonate, potassium silicate etc.

Simple ph up is usually potassium bicarbonate.
 
They look pretty good so I wouldn't say it has damaged them but it sure wouldn't have helped.

I can't get that till Saturday from amazon. I'll just need to lower my ph slowly because I've no ph up. I'm glad you said. I've been nuking them

Can use it in a pinch but I would definitely order something else.

Don't use more than a tsp per 5 gal.
