lower leaves yellowing in 3 days?
Over the past 3 days my 2nd plant lower leaves started to yellow. Both are fed the same amount and the same rates. I noticed the one that is yellowing the leaves are upwards and that is a good sign, but the lower leaves are yellowing too fast. I am unsure what could cause this.

Jaunissement, excès ou carence ?
My Amnesia is showing rapid yellowing of the leaves. I thought it had a nutrient excess because the tips were burning. I did a flush and put in a light feed to start over, but the problem got worse and the yellowing accelerated. Thanks in advance! 🌱

Possible Nitrogen Deficiency?
Is this a nitrogen deficiency? I had a yellowing leaf or two at the bottom of the plant which have since dropped off, but rest of the plant is looking patchy now. I have just switched from fish mix to bio grow.

1st plant. Seems stunned and yellowish with black dots tips. Can anyone give a hint?
Hey, guys! How are you doing? This is my first plant. It is 4weeks old, planted on cocó-perlite mix. I find it growing too slow based on other diaries, and it is starting to show these yellow with black dots tips. Anyone can tell me what’s going on?

CalMag or something else?
Discolored leaves at the bottom of a 3 week young auto flower, full feeding schedule in diary. Was thinking Cal-mag deficiency, but after 4 days of running 2mL/L Cal-mag supplements it's still getting worse. Could it be lack of phosphor, and will BioBizz FishMix/Grow be enough?

yellow spots on upper leaves, towards the end of flowering, I grow in a Coco ,flowering 8/10
This is my second attempt at cocus I work with Plagron nutrient solutions(Coco Nutrient) I follow the table, there were no problems on my first try.. should i stop nutrients? I always mix the water in a bucket, so I can't spoil it either, because most of the plants are healthy, ph 5.5 is always between 5-7!

yellow/copper appearance in some leaves after first run off watering
hi! after the first run off watering the girls seemed alright, sturdy and firm but some of the leaves (one leaf, 3 plants currently) experienced copper/yellow/orange tints . this is only on old leaves so looks like mobile nutrients. could this be cal-mag issues?

¿Quemaduras del foco?
Are these colors on the leaves normal? There are some leaves that have turned a yellow color that scares me. I don't know if I have the light too close, although I don't see any signs of burning. What do you all think?

Hi, I'm sorry, I notice that this plant has a slightly yellowing top. I don't know if it's due to the slight burn it got about 2 weeks ago or a lack of micronutrients. I've been watching this for over a week and it hasn't gotten much worse. When I had a micronutrient deficiency...
