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 ! 🌱

What could it be?
I'm a relatively new grower and I don't have a diary setup yet. I know it's hard to diagnose a problem when there is no diary, sorry! They were good until they started to yellow. They are in their 5 to 6 weeks of flowering. Some are good some are yellow and I feed them the same.

HELP—Trained eye needed for a nutrient deficiency diagnostic!!!—HELP
Can anyone help me with diagnosing what appears to be a nutrient deficiency? I used Jobe's fertilizer sticks (13-4-5) [I know, horrible stuff but its all I could get for the next two weeks] which I diluted to 1/8, 1/4, 1/2 of the recommended amount as per label. CHEERS!

End of Flower, Yellow and crusty leaves ok ?
Hey last weeks of flower and I’m not sure if it’s fine how they are developing, as I started flushing this week they quickly started developing yellow crusty leaves. Should I keep flushing them as I will cut them in 1 or 2 weeks or should I try to balance out missing nutrients?

Weak yellowing leaves
Not every single time but quite often my plants are turning yellow in the middle of flowering. It starts from bottom and follows to top. I can basically “take off” leaves off stem and the upper ones getting dry and brittle. I’m also quite sure the ph level is correct. Any guess?

Yellowing and dropping of leaves
Does anyone have any ideas what could cause the yellow and dropping of leaves for the Royal Jack. All plants are treated the same. The growth is stagnating as a result.

overnight yellow leaves with brown spots
These leaves (about halfway up on #1) turned yellow with brown spots overnight. I didn't check the soil before giving it nutrients two nights ago so I was wondering if it has to do with overfeeding. The soil is damp and kinda packed together. Any idea what's going on?

Browning leaves? Did a soil slurry and dropped the water from 6.8 to 6.2. Does that mean it’s locking out? How should I go about fixing this? In peat pearlite and worm castings. Added about 6 cups of lime to the 20 gallons of soil thought that should have helped the ph?

I had a ton of my fan leaves going yellow this week (week 6 of flower) and I am a bit concerned. I know its normal but it seems a lot went yellow fast. Think this plant will make it to harvest okay?
