Could well be a potassium deficiency appearing or some lightburn as it is quite even and uniform.

Leaves turning yellow
Leaves are going pale and turning yellow all over the plant. Temp 25c, humidty 35-45 %. Bloom nutrients every second water. Two 150w lights over plant Thought it might be over watering but only giving 400ml now every 2 days - 3 days and still seems to be progressing on the plan

DWC: Brown spots and pale leaves on the 2nd week
What's up with these brown spots, is it calcium deficiency and slight paleness? Nutes: CaliMagic 2.5ml/gallon, MaxiGro 0.3tsp/gallon, RO water, total 0.9EC - res was changed 6 days ago. Should I worry?

Leaves color changing in flower!!!!
what do you think ? deficiency? or is just normal for leaves to become like this after 7 weeks from seed of an autoflower? max i fed was 400pm just once. I don't think thats overfertilization. Maybe ph lockout? today i fed with 4.5 litres of compost tea + enzymes! pots are 14L.

Leaves turning white and now dying off.
Gelato is turning white and foliage is dying off. I had soil drainage issues and repotted with different soil. I believe humidity and lamp to plant distance is fine. What's going on?

Sehen nicht gesund aus
The two here don't look very healthy. One is very pale green - leaning towards yellow, and the other has weird spots on the leaves. What could that be? I hope it's not what I'm fearing.

What's causing the leaves to lighten?
It's day 10 and the first set of leaves are starting to lighten in colour. Is this related to Cal-mag, bleaching from light, or possibly nitrogen? Using FFOF with PH'd tap water adding Cal mag. Mars Ts1000 at 30" on 55%.

Will a humidity dome help speed up recovery or will it have negative affects? Put random category since mine isn't listed. Plant was waterlogged so I transplanted it and want to know if a humidity dome will help recovery

Why are my leaves curling down?
I have some Sour Diesel autos that are about 5 and a half weeks old. They are just starting to move into flower, and I have some leaves curling downward and slight discoloration. I’ve already amended with extra cal-mag and doesn’t seem like much has changed.
