Looks like heat stress ,if your light has a dimmer try turning it down some. If no dimmer then raise the light if possible.

Problem with plants in the 3rd week of vegetation.
I'm posting again because I accidentally marked it as resolved. I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.

Leaves turning yellow/pointing up, stem turning purple
Having a problem with one of them.. all the leaves have gone very yellow and are pointing upwards. The stem is also very purple now. Any ideas what this could be? Other than a feeding of bud candy and watering here and there it hasn’t gotten any other feeding. Thanks!

Discolored, burnt and curled up tips on higher leaves
Several symptoms, always on tips of higher leaves : they are discolored/burnt or burnt/curled up. LED @40cm (deemed 70% of 300W) and I just gave them the 2nd flowering feeding, 4 days after first one (pots were very light). I was planing to start compost tea... What should I do ?

My plants are suffering a Phosphorus deficiancy 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. what should I do? I went to check on them today and the amount of damage they took in 24 hours was bad.

Fan leaf deficiencies during flower. To cut or not to cut?
Day 85 Update: G13 has a ton of fan leaves turning fast. Pretty sure it's a PH issue. Should I wait until they're dead to trim them off or get rid of every fan leaf that is affected more than 50 percent of the leaf?

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.
