Plants aren't doing good.

[Rurumo]

my tap ph is 7.4 with a lot of calcium in the water (alkaline) and dtw coco actually works out perfect with this type of water. Take your water, add nutrients, and adjust down to 5.8, then feed. Even if the PH creeps back up once it's in the soil, if you are feeding at least twice per day, you are giving your roots enough contact with that lower PH feed for them to take up nutrients. The key point here is you need to feed at least twice per day, once your roots have filled out their pot...so, during all of flower for ex. Some people feed more than that, but it's a PITA if you are hand watering, so twice is fine.

I'm up north, my waters hard, I can leave a nutrient mix after PHing all week and it will be pretty much where I left it.

They don’t come much older than me. Stop that shit. Slap the fool who told you to do it for me.

Thank you my dude, I'm just going to get straight to the point and add the nutes and PH the water and feed them

I'm currently on a Blumat system, so for the first time I have a reservoir and sitting water with nutrients & pH adjustments. I had some moments of worry about pH drift while literally sitting for a week. I fixed the situation by not checking the pH once I put the water in the tank.

Plants haven't seemed to notice.

Another reason why I let it sit for 24 hours is so the water can turn to room temp. Because right now it's coming out the taps at around 5c and I know feeding cold water to plants can affect things? lol or maybe I am wrong again lol I don't know.

I think that's my problem. I sit there all day worrying about the PH drift lol

I honestly don't think there's a harm of letting it sit for a bit once out of the tap, but just don't do anything to that water until you're ready to use it.

Harry,you need to get it on bro.

I set the PH to 5.8 and put it straight into the plants, hopefully they like it the E.C is 1.5 and the PH is 5.8

Hi guys, my plants aren't doing good. I am in coco and my PH is 7.2 which I am struggling to lower because every time I add PH down the PH rises back to 7 after a few hours and from the research I have done it is due to the buffers in my tap water which is stopping me from lowering my PH. So that is my first problem. Another problem is some of my plants are looking okay and some are looking yellow, almost like they have a nitrogen deficiency which I am struggling to correct. I'm mainly focusing on any new growth and it is coming through green which is a good sign?. My E.C is 1.5 and temps are between 27c and 29c. I can provide pictures if needed. They are under a 600watt HPS at about 28 inches away from the canopy. They are around 5 weeks old. They started to turn yellow when they became root bound in 1 liter plant pots at 4 weeks old. Maybe that is the problem for the yellow and droopy growth? They seem to be doing a lot better than they were but it seems like I am still struggling along. Any help is appreciated. Cheers guys

What are the details of your tap water before you do anything?

What is it’s EC? And what is it’s pH?

Are you using a recirculating system or drain to waste?

Chlorine dissipation is a myth perpetuated by “old school growers”

Here’s my setup.

60litre reservoir.

i refill this twice a week with 25L each time.

when I refill I add some hot water into my 25L container and then fill up with cold on top.

usually this makes the water tepid.

i add my nutrients and mix well then set pH.

then I refill my reservoir (I am drain to waste)

i make sure my EC is where it needs to be (to show you I’ve included a pic of my plants which haven’t exceeded 1.4EC and are currently fed 1.0EC 3x a day)

then after my circulation pump has run for a good 10mins I check the pH of the res and adjust if needed.

I never use neat pH down. I always make a solution of 10-20ml pH down and 80-90ml water and fill up a 100ml bottle with solution to use.

My tap water on it's own has a E.C of 0.5 and the PH is between 7.0 and 7.5 I'm handing feeding with a syringe in coco.

Coco needs to be wet constantly
How do you accomplish that with a "syringe"?

I am treating it like soil. I let it dry out and then feed them with about 1 liter of feed at an E.C of 1.5 (20ml of canna A and 20ml of canna B per 10 liters of water) And some rhizotonic to help promote root growth? They are in 10 liter plants pots now. I transplanted them about 1 week ago. I just sit there with a 60ml syringe lol

I can't find any info on it being a good idea to let coco dry
Got a link?

First coco is not soil
It is hydro and he clearly says there is a difference
You letting your plants dry out in coco is causing your own problems
Good catch but the link just proved my assertion

Should I give her a feed then because she's drooping like a bitch. The coco is still slightly moist but she is drooping a lot compared to the rest. The new growth is coming through green but the rest is yellow underneath

Do some research on proper treatment of coco

Do you know where I can find some info? my plants are dying and I am going to have to attempt to flower them soon just to try and get a few ounces if I can't fix it.
