Curled leaves occurred in both veg and flowering tents only to my purple trainwreck plants. Checked leaves with a loupe and couldn’t see signs of any pests at all. Only occurring on my PT plants in all tents. Other strains seem 100%. Only on large fan leaves, any ideas or help?

Purple spots on leaves?
A few leaves have started showing purple spots, some with pale green/whitish bits as well. Picture above. Any help would be great. I’ve been feeding on the BioBizz schedule every second watering, usually every other/every third day.

Recurring Cal Mag issues
I’m already at the maximum recommended cal mag dose of 1ml/litre (with nutes at 1000ppm or E.C. 2.0) and I’m still facing issues. It went away for a few days, but it’s now back. Should increase the cal mag dose and cut back on the macro nutes to maintain 1000ppm?

Mottling shiny spots in leaves/ nitrogen claw
What is the cause of the mottling on these leaves is it some sort of toxicity? Please look at my last diary entry (week 4) for info on recent feeding.

Phosphorus Issue?
Slurricane is having a phosphorus issue and not drinking water as fast after transplanting. I’ve been feeding cal mag every water and thinking it’s a root zone issue. Should I apply stop watering and apply a follar feed of 3 part general hydro nutrients?

What's going on with my clones? Do not have much information to add. VPD is not terribly off, DLI around 25.
What's going on with these clones? Not sure what it could be. They could possibly be rootbound. They should have been transplanted a few weeks ago but I did not have the space.

Weird leaves
The leaves of my plant look strange, I'm not sure if it's CalMag or something else. I recently overfertilized the plant a little..... I am also fighting tripes on the plant at the moment Could it also be the PH value? Thank you :)

Hi! I have spots forming between the leaf veins. Most are a red/rusty color and necrotic but a few are purplish red and still flexible like the healthy part of the leaf. The only affected leaves are near the top of the plant but not the very top either. Do anybody have an idea?

Weird Spots on almost every leaf overnight? (Leaf Burn???) My plant developed these spots on the leaves basically overnight...
I was looking after them just yesterday evening and the plant was fine, however I did a mistake. The left plant got completely wet (i had to move it through the rain) and i did not dry it before the light went back on. Right plant is completely fine. No pests (thrips spimis etc.)

Leaf Spots, weak color, and leaf ripple
Please help me identify possible causes of this: small spots on leaves, minor color fade (not burn) along edges, and strange 'ripple' effect. A user commented that he thought my plants looked deficient but hasn't elaborated further yet. What might this be? Multiple issues?
