What’s going on here guys?

[Joshua1876]

[Joshua1876]

Ppm 1200, ph 6.7. Week8 of flower. Only top portion of plant is doing it. I water with RO. There’s been times when I didn’t put calmag in water.

Nutrient burn and a lockout from the looks of it.

In general this happens to most plants in late flower, I would drop the Ppm down to 600 and the plant should be ready to chop in 2-3 weeks

[CamZ]

Disagree. This is abnormal and should not happen.

[Mark]

This is one of my crops and I had a few of plants looking like this, the leaves on my plants near the end of flower tend to go all types of colours and start to die, thought it was normal.

[CamZ]

You had some irregular burning and natural senescence mixed together. His picture is more aligned with severe overfeeding or lockout.

[Joshua1876]

I don’t understand how I overfed. I top dressed 1 cup craft blend mid flower just like Chris said.

[Joshua1876]

I even run c02 so the plant can handle a higher ppm

[Mark]

I do the same Joshua1876, top dress, week 2,4, and 6.
nute burn tends to start at the lower part of the canopy.

[CamZ]

Every cultivar is different. I’m not sure how it happened either, just giving my opinion.

In my personal experience, nutrient burn happens more toward the top of the plant because it transpires more than the rest of the plant due to its proximity to the grow light.

Whats your ppfd?
