so you have studied chemistry and understand buffering?
No one uses vinegar for pH control, get some nitric acid, bin the autos start again

How is it ever not feasible to grow a photo period inside? Perplexing!
Keep your ph 5.8-6
Water until plenty of run off
Run your nutrients at 1/2 to 2/3rds of the canna online chart and know if your water is soft or hard, Hard wants less dose, soft wants higher dose.
Sort your temps out, extract properly.
Not sure how anyone can have high temps this time of year unless they are not extracting and exchanging air.
What slipper was saying I assume is don't chase your run off in coco. PH will change, EC will change. Worry about what your putting in.

im a 3rd year chemist so go nuts with the lingo mate
is there any other acid i can use or would you recommend nitric specifically? got access to phosphoric and malonic atm. im guessing you didn't say commercial ph down for cost reasons?

Problem is he’s growing snide weed, who knows what nutes they need, kill all autos imo

Ok mr chemistry why do you want a weakly dissociating acid?

haha might sound like im being lazy but i didnt want plant height to be an issue; got a tent with 1m height - although judging from how people speak about autos, might be worth making the switch!
okay awesome i'll try all of that - the temps are cos im growing in a closet. will chuck another fan in later this week

haha mate i just got the sarcasm in your second reply, didnt mean to sound like a dick if i did, only used vinegar because its pretty stable at the pH i wanted the feeding water to be at

All the more reason to go with photos, you have control, you do the training and manipulating. Autos do what they want. Little twats
You want phosphoric acid fella , you can use that any stage, you can also use nitric acid but only in veg.

Lol this is a funny place, some here are really good growers, some do it for a living, acetic acid is for chips, why do you think (as a 3 rd year chem undergrad?) your pH runoff is high when you water with 5.5?

that makes sense mate, thank you. i'll make the switch when im next in the lab. will grab some nitric like you said for veg and then phosphoric the rest of the way

The height of 1 m will seriously affect your ability to grow, most of us use 1.2x1.2x2.0

i know man, honestly wish i had the extra height so i could get some fatter yields but this is the best i can do right now (stealth is a big big issue), more so than yield because the product is just for myself. im more concerned about quality and learning the process, glad a place like this exists!

i have done regs in 9 to 10 weeks in 12/12. you just need an indica leaning finisher.
p.s holy midget plants...1m is not a lot.

from seed germination to chop. the grow is on riu somewhere although the pics are not anymore. was one of our deep blue strains.

heres the thread....like i said. all pics have been lost thanks to riu server wobbles.

funny...2nd or 3rd page and autos are getting slagged off lol.

Just buy PH down. It's actually made for what you want it for. Just add it one ml at a time in ten litres of nutrient solution. Obviously it's the last thing you put in and if you go too far don't be tempted to add PH up to correct it. Start from square one again.
Also I concur about the photo plants. You have zero control over autos. I have never touched them but I've seen some and they vary a lot from the same strain. One can be like a small bog brush and another can be massive. If you go 12/12 from seed or one week of veg you'll keep them small. The only problem is if you find a winner you won't have a clone to grow it again. Unless you keep a couple of buds on the plant and re veg it.
Good luck.
