Hi, low grade heat stress. Nothing to worry about at the moment. Shade your pot, this will be sufficient.

I think my plants are suffering a Phosphorus deficiency due to lockout due to low ph of soil. My first flush only helped for a while. As soon as the medium gets too dry damage resumes. I went to check on them yesterday and the amount of damage they took in 24 hours was pretty bad5y ago

Too Much Light?Top looks yellowish, more so IRL than in the pic and the new growth is kinda taco-ing. Just under 24" from the light, 78F and using Photone the DLI was at ~30. I don't really trust that app but if it's even sorta accurate, 30 might be high with no CO2? says their charts anyways.Leaves. Curl up

Leaf Symptom DiagnosisThe leaves (pictured with weird wrinkles and crispy edges) are showing some form of stress. Theory is that they were dehydrated from the overly salty medium, but I'd love to hear from a more experienced coco grower about if and how I should intervene to alleviate the stress.Week 7

WHAT IS CAUSING MY LEAVES TO CURL? (Day 64 pictures)The leaves at the top of the plant seem to be curling up. My first guess is that there is too much light. I recently moved my light down to 12 inches above the canopy. The PPFD should still be under 1,000, but I don't know what else could be causing it. Please help. 🙏6y ago

Sudden Leaf Yellowing – Lighting Issue or Something Else?Hello! Yesterday, I noticed the top leaves turning slightly yellow, but today it looks dramatic. Check the pictures—leaves are yellowing and drying out rapidly. It’s only affecting the central leaves, so I suspect a lighting issue, but I’d like to confirm before taking action.Leaves. Curl up
