Hello All,

Soil: Mother Earth Coco/Perlite 70/30
PH: 5.8-6.0
PPM: 2400 (this strain loves high ppm)
Strain: Incredible Bulk
Using Octopots
Temp: 76
Humidity: 68
CO2: 700ppm
VPD: 1.0 kPa
Nutrient Line: Athena

What is this?

Any help would be appreciated.

Thank you!

What is showing is a deficiency in Phosphorus. It is often ph related, but it also could be a lack of P. Carefully consider ph and also what you are feeding.

I am leaning more towards a phosphorus toxicity as the PH is fine which in turn is causing a cal mag deficiency.

No plant likes 2400 ppm. That sounds ridiculous. What scale are you using to measure?

2400 is crazy high...I don't run CO2 so I can't say about with that added...I'm at 600 in flower (Hannah scale) and have no issues.

Toxicity imo would appear with burn and curl somewhere...we only can see a few leaves.

I agree I also saw what appeared to be some cal def in first pic or 2. The last one is similar to purpling that can occur mid to end of flower...but again imo it's a P def SHOWING...doesnt mean add P!

2400 is 300 over what it is supposed to be which is 2100. Latest nutritional science have shown that plants in media like coco can take a higher ppm. Couple that with a strain like IB that loves higher ppm and there ya go. 2100ppm is the target.

wow that seems crazy high ppm. I don’t ever go over 800-900 at most but these plants are strong so maybe they can take that much food. I just wouldn’t ever use that much.
