Hello :) First time grower here currently growing an auto that's one week away from harvest and a photoperiod that's been vegging in the same tent the whole time (12 weeks) The reg plant is in a 3 gallon plastic pot. It has had roots showing through the bottom slightly pretty much since week...

I've been watering at 6.2/6.3 for a couple weeks and I feel because I've been using too many nutes plus low pH that that was lowering the soil pH. Thanks for your advice anyway. I'll keep all of it in mind and see how it goes.

Okay thank you. I guess that's why I've been extra worried because I felt as though I had a specific time frame to get this sorted out or the plant would be write off.

Also I know you've said the plant has another 6 weeks, but this is an autoflower that been growing for 10 weeks already. Will it go another 6 weeks? It's harvest time is supposed to be 11-13 weeks from what I've seen of other grows. If I try keeping it going for another 6 it won't herm?

That's why I thought I'd I used RO water and gave it calmag and whatever other nutrients the plants need and Ph'd it properly that would work? Last time I watered I did at at 7.2pH because I know my soil is too acidic and the run off cam out at 6.9ph. I'm not 100% sure what the soils pH is. The...

Great thanks for your advice. I've ordered some calmag. So if I try this and it's doesn't help try lime?

The light I'm using is brand new so I'm gonna say from what you've said and what I've read it's water for sure. Probably stunted it with too many nutes too now I'm learning more about it. Nevermind. It's all a learning curve.

It's 277w from the wall. I've lowered it recently to just over 12" from the canopy. It started week 6 of flower on Thursday

Hey, sorry I have one more question for you. When I get the water, do you think it'd be a good idea to treat the water how I want it and do a little flush? Or should I just start watering? It's possible I'm not going to be able to get the water until next Saturday, and at that point I'll only...

That's alri

Thanks for all your help. I'm gonna give RO a try and I've picked up some calmag

I've found some ro water being sold 12p per litre at a local aquarium shop. If I use RO water would I need to start using calmag as well? Do you have any experience with RO water?

Okay great thank you :)

My ppm is 563 so I think that makes the ec around 1.1? It's a lot :/ I've stopped nutrients at the moment so I can try get a hold of the problem. Do you have any suggestions of what I could do?

Having a look it seem that hard water already has a good amount of calcium in it, and my tap water is particularly hard so hopefully if I just keep watering at a high pH that might do the trick.

I'm not sure. I've never thought about that. I'll have a little look and see if I can find anything :) thanks for the advice

Yeah :/ that was the next thing I was gonna check cz I didn't want to cause more problems with too much mg. I really just want to get the soil pH sorted so then it can take up the nutrients it's supposed to itself. But if I can give it a little CA boost I'm sure that'd be good for now

I'm in UK. Thanks, I'll have a look and see if there anything I can here that's just ca

Yeah I know, and I'll probably add it into my soil mix at the start of my next grow. But I can't do that now unless I sprinkle it on the top. I still have questions that haven't been answered. Hopefully someone who has some sound advice with reply soon

okay. This has kind of went off point for me, the OP. I'm sure Ballzmageetree can take what you've both said, do some more research, and figure something out. Can anyone please give me some more advice? It's fine going "use dolomite lime", but can you elaborate? Do you have any specific tips for...
