This looks like it could be ph lockout . Try flushing your plant and see how she does

Hi! Check on "tobacco mosaic virus". The yellowish stains could be signs of it. Good luck!! :)

Kind of looks like very weird Potassium excess. Could be a form of PH lockout.

Problem with yellowing?
In the 4/15 10am photo taken from above, does it look like the top leaf is yellowing a bit? Maybe hypervigilant, just want to be able to react quickly, if so.

Imagine
Yellow Leaves with necrosis
Hi, My weed have some troubles, i can see some leaves becoming yellow with some "yellow points" .. At the end of the leaves, it is, i guess, some necrosis and it's curling down. Could you help me please ? I think it's a calcium deficiency but not sure.

Jaunissement, excès ou carence ?
Ma Amnesia présente une décoloration rapide des feuilles en jaunes. Je pensais qu'elle avait un excès car les pointes brûlait J'ai effectué un rinçage et mis une alimentation douce pour repartir mais le problème s'est aggravé et a accélérer le jaunissement. Merci d'avance ! 🌱

Sénescence ou manque d'azote en phase de floraison.
Les feuilles virent au jaune rapidement, se propageant aux autres. Je les ai privées d'azote pendant 10 jours en floraison, pensant que la terre enrichie suffirait. Doute entre manque d'azote et début de sénescence. Voir mon journal pour plus de détail. Merci beaucoup 🙏

Brown spots and yellow tips in flower, started around wk 8-9. Thanks!
My 10wk old Auto Trainwreck started showing brown spots and yellow tips @ wk 8-9 but even after up'ing Calmag to each water wk 8 (1tsp/gal) it's everywhere now. It's been 75-50% the whole time- deficiency in late flower? Again big THX to the community - for more than just this.

Possible light stress?
Any help would be much appreciated, so the leaves are looking with a yellow tinge , my thoughts were light stress as had lights on 24/7 on to high and to close I have since then back off on the power of the lights and move them further away from the plants and changed to 20/4.

Brown/rust spots and yellow leaves at the bottom
Plant in late veg (soil) is showing spreading brown/rust spots on upper leaves and rapid yellowing on lower leaves. Frist only at one plant and now at the others too. I suspect a pH-induced Cal-Mag lockout. But I always check pH to be around 6,5. What should I do?

Start feeding two weeks into (auto)flowering?
Two autoflower plants around two-three weeks into flowering. One plant is getting light green and yellowish leaves that feels papery. I have not given any extra nutrients (just nutrient rich soil to begin with, a little over 20 liter). Should I start feeding now? Or is too late?

Lockout during transition
Just a random question. I'm growing in a tent using coco and perlite. How do y'all keep your plants from getting nute lockout when they go from veg to flower? I seem to have this problem with every grow, no matter what I try with them. Thanks for any tips. ✌️ 💚 🌱
