white spots on fan leaves

jim59 · May 21, 2022

needing info please i have 3 photo plants growing in back sun room that 1 of them has white spots on fan leaves and i do not believe it is mold as it wont rub off and ive tried baking soda and water mix to wash off but the spots seem to be internal in the leaves. this is just my 3rd time growing and hadnt had any problems the last 2 times with the same soil, growlight, weather conditions as ive just tried to grow as natural as possible without using chemicals just the way it is intended i think my opinion! can i cut off those leaves as they are just fan leaves? the plants are about 8 to 12 weeks i think as i forgot to write the time down that we planted it. you can see in the pictures residue from the bs and water on leaves so any info is greatly appreciated. moisture is good plenty of sunlight and when there isnt any i just use a 20 watt led grow light from walmart but thinking about increasing that but like i said just wanting natural. someone told me that if i wanted that that i should raise autos instead which seems to me that might be a better option. thanks jim59

A whole plant picture would be better. That said, your plant looks pretty small and the leaves don’t look diseased or have a pest problem, so I’d just let them be. The larger leaves will work as storage for mobile nutrients and by removing them you rob the plant down the road. On the other hand as your plants get bigger and you have lots of leaves there’s no reason to hang on to unproductive ones that block light (and just bum you out).

It's not any deficiency that I know of. Could you have gotten some kind of liquid on the leaves? Have you scoped for pests?

as i said in the previous post i used baking soda and water mix and that is the residue on the leaves that your seeing and doesnt affect the white spots and not pests
