Phosphorus or calcium

Ckbrew this is the recipe used. I have 4 gallon container so 3 gallon Coco 1 gallon petite 9oz of castings

[No3odiesShad0w]

Yeah I think that's been my mistake. Just overthinking everything. It does say in the NLS website to do 6.5ph. Not sure how I missed that. Just gonna give that a try starting tonight. Would be a shame to have such a nice plant underperform

I'm using the canna coco. 75% with 25% perlite. I ran water through it and had an EC of 0.3 so I used it as is. It's supposed to be pre buffered .....I never used Coco before I was just so fed up with soil over the last 3 years. I heard all the stories about ppl buying bricks of Coco and it's trash so I spent the extra money to get one that's washed and buffered. I've been adding between 3.5 to 5ml/gallon(GH cal-mag) of Cal mag to the water every time I water. I held back for 2 waterings because my leaves were almost purple. Now I think I need to just give it normal strength again.

You didn't say what the percent coco is but from your description it sounds like the majority. Did you pre-buffer the coco? Coco will bind ca and mg. It should be soaked in water with calmag before use. I use 10ml/G and pH adjust as needed. This saturates the coco so it will not bind up ca and mg from the nutrient source. There also may be a pH issue. With the mix you are using idk where it should be.

I think that recipe should be treated as if you are growing in living soil

[No3odiesShad0w]

Then you read stuff like this and I just think well I'm not in Soil and 6.2ph seems to be the middle point for both so I was just sticking with that. But 15 days into bloom clearly it's not it ..... Good thing I have to water daily..... Today I'll water with 6.5ph I gave her a strong tea yesterday. If the pH is the issue. Raising it shouldn't be hard in the Coco since it's been fairly stable unlike the shit Fox farm soil

[No3odiesShad0w]

Literally following their recipe. Only thing is ice been keeping the pH at like 6.28 -6.22 but I guess next watering I'll do 6.5. I did just notice they keep saying 6.5 on the site even though it's Coco

SOOOOO much conflicting info when it comes to weed. This is why I hate bro science. Just muds up real science

[No3odiesShad0w]

Coco with organic amendments....I was thinking about raising the pH to at least 6.3 but everyone I ready about Coco keeps saying 5.5 to 6.2. But I'm not running synthetic nutrients. I'm doing what I would do in soil but in coco. I kept having problems with acidity with the soil going down to like 4.8ph so I figured I try Coco. Everything was going really well until it started blooming. ...... Same problem.

I'm beginning to wonder if the problem is the nature's living soil because that's been the only constant throughout this whole problem finding mission.

I do not know what your grow medium is, but if it is soil, 6.2 is too low. I needs to be around 6.5-6.8. The low PH, if in soil is resulting in nutrient up take inhibition especially in calcium and magnesium. Higher PH and Cal-Mag should fix your problem.

[Rwise]

Raise the PH to 6.5-6.8 with soil in flower.

VPD is at 1.13kPa, CO2 between 900 to 2000ppm DLI is around 46 ish 47ish. I could probably push that more but not if I have deficiency. I think I'm just under feeding for all she's doing in so short .....I never really had all my stuff locked in .... Never had anything grow like this before.

[No3odiesShad0w]

This getting me so annoyed. Different medium same problem. Ruled out the pH. I got 6.2 going in and 6.2 coming out. I'm thinking....I might be under feeding? There's a crap ton of flowers and they're already stacking on day 15 of the bloom. I gave her a healthy amount of NLS flower power 10 days ago but I think it might be time to make a tea and water her with that.... pretty sure she just needs more food.

Other possibility is calcium but that wouldn't have the red stems issue.

Secondly wtf is the matter with uploading pictures. I've never had a picture I posted under 2.0mb and now all of a sudden every picture is too big over the 2mb limit.... Good luck seeing stuff properly at lower MB.
