Hard to see under the grow lights. Try taking a picture with the grow lights off so we can see the leaves proper colour...

Leaf discoloration and curling
I’m not sure what’s wrong but all my other plants are fine. It’s in pearlite and peat moss and I’ve been watering with ph balanced water. I did use a very little bit of half strength dyna grow but I only did a little squirt.

Leaves curl on upper new growth and mid but not lower.
I’m using the canna coco line except boost, looks like phosphorus deficiency. I just lowered my a and b 0.7 ec and added 0.3 of pk for a total of 1.0. Is this phosphorus deficiency and do you think my changes will help. Leaves are a little dark shinny and the shape is odd.

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 ?

Hey guys. Leaves not curling upwards as such but I'm getting some leaf tips that seem to be reaching upwards slightly. Does this mean I need to up her cal and mag intake? I read somewhere if the leaf tips are starting to "pray" towards the light it could be a cal/mag def?

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 bad

Leaf tips on all my grows turn upwards slightly. I'm using a 260w HLG Quantum board LED light which is about 2.5ft away from the plant and temps never get higher than 27 degrees with about 60% humidity. Could it be calmag deficiency?

Burnt? PH lock-out? too much Cal-mag??
What do you think is wrong with this plant? All the other plants surrounding her are fine so I'm not sure what went wrong with this one. I thought it was cal-mag deficiency at first so I doubled cal-mag when feeding but it only proceeded to get worse. The buds look fine tho 👍😳
