Help me! What's going on here?

Can anyone help me with what’s going on here? This issue just keeps getting worse, can’t seem to fix it

 

[Embrace2mrw]

Sorry for the shitty thread, first time using a forum. Trying to figure this out lol

 

[Calvados]

Some details please. You look about half way through flowering. What kind of light are you using and how far is it from your plant? What kind of soil and neuts? Are you in a tent? What's the temperature and RH. Basic details help a lot.

 

[Guy Cavallero]

Ph too, can you measure yours? Have you changed anything lately?

 

[Embrace2mrw]

Thanks guys. I'm using a blackstar 240 LED, it's about 16 inches away from the top. Yes she's about half way through flowering. Soil is promix Bx mycorrhizae. Using botanicare cal-mag, and GH floranova. I use a closet, temp around 75-77, humidity is between 50-60.

Haven't used nutes for about 3 weeks because of the issue

That all sounds good. What are you PHing your water at. What kind of ventilation do you have? Is this a photo or auto plant?

Have you flushed the soil? Do you know how to do that?

 

[Embrace2mrw]

I ph every water, and measure the runoff every time. Currently phing the water to 6.0, and the runoff comes out at 7.0. It's an Auto Ultimate. I have flushed the soil. I get a little runoff if I water with 1 4L jug, recently I've been watering with 2 4L jugs so I get lots of water draining out. Something else you would suggest I try?

 

[Calvados]

I thought Promix PH was 6.5. Whatever it is I would flush the soil right now until the run off was correct. Your roots won't absorb the neuts until you reset the soil. After that I'd give it 1/4 strength floranova right now. And half strength calmag.

 

[Embrace2mrw]

By quarter and half strength, you mean based off the recommend doseage on the bottle right? And what do you mean by flush the soil til the PH is correct?

 

[Calvados]

I don't know the correct PH for Promix BX. If I was guessing, I'd say it was 6. You need to find out. Assuming 6 is the number run water PHd at 6 through your medium until the run off reads 6. Then feed them neuts at those % strengths based on the recommended dosage for the week you are in. Reset your soil so your roots can absorb the nutrients.

 

[Embrace2mrw]

Thanks a lot for your help man!

 

[Embrace2mrw]

How am I supposed to determine the right ph for promix? I don't exactly understand that. Isn't 6 too low?

 

[Calvados]

Every grow medium has a proper PH range. I can't help you past telling you that. You need to look it up.

 

[Embrace2mrw]

Hm... so the water going in should be in that range? And don't worry about runoff?

 

[Embrace2mrw]

I was able to find the data sheet for the soil. Can anyone help with understanding it?

 

[smeghead]

Hi embrace..
Never used that product. .but the way I see it the promix has a good ph range of 6.2..I never bother measuring water coming out the pot, as long as the ph of the water going in the pot is 6.2 you should be golden..
You said no nutes for 3 weeks. I'd start using your flower nutes again, half strength Ph 6.2.
The coloured leafs are gonna stay damaged but the buds will be alright and fatten up.
I actually like her colour.

 

[Embrace2mrw]

Hey Smeg, thanks! So as long as my water solution is above 6.2 I should be good? Think I should be using my calmag still?

 

[LB07]

Hey Smeg, thanks! So as long as my water solution is above 6.2 I should be good? Think I should be using my calmag still?

No. Water your plants AT 6.2. Nothing more nothing less.

 

[Embrace2mrw]

Hey LB, the data sheet for promix bx says greater than 6.2 after 7 days. Why do you say exactly 6.2?
