Large leaves starting to yellow and brown.
Themythicalchristineanswered grow question 3 years ago
It looks like the beginning stages of a magnesium or a nitrogen deficiency, when the light is nice and close the plant will eat up the calcium and magnesium very quickly.
If the PH of the substrate is too high or low you may run into other deficiencies or abundance’s causing a burn.
I would start with confirming the PH of the substrate and the water first.
Whatever the culprit it still seems very mild; and you have a gorgeous plant!
Good luck and happy growing

Hello. When I watered 3 days ago, I saw some brown spots on the lower leaves and thought I had got some nutrient solution on the leaves but now it's on the next set too. Any idea what is going on? All 3 plants are being treated the same. Thanks Chuck.

What could be causing these spots and burnt tips?I noticed this starting this morning, the pH was 6.3 and 210 ppm. The water was about 7-10 days old. So I figure water change time?

Spots on leafs, and lime green topsI am beginning to see leaf damage again, so i would like to ask if you guys could point me in the direction of my problem. I suspect either light damage, or ph issues building up over time. It started before i gave the first flower nutes, tops seem deeper green since that though

What's going on with my clones? Do not have much information to add. VPD is not terribly off, DLI around 25.What's going on with these clones? Not sure what it could be. They could possibly be rootbound. They should have been transplanted a few weeks ago but I did not have the space.

Orange/rust spots on leavesThroughout the life of this grow I've seen rust and orange spots on some of the fan leaves. I can't seem to figure out or pinpoint the source of this. I think the plants are in good health overall, I do have a lot of fungual gnats that I'm trying to mitigate

yellow spots on upper leaves, towards the end of flowering, I grow in a Coco ,flowering 8/10This 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!

Please look at the leaves shown, orange and dried parts. I asked a similar question earlier but these look more damaged and I'm wondering if it's worsened due to my setup. Wind damage from fans? Water damage from humidifier? Light or heat damage? Managing VPD is tough. Thanks!

White/Yellow snipes on leaves? (13th day of growth from seed)I noticed a huge change in my plant leaves in less than 24 hours. The leaves look like they are getting burned out. What is happening? I'm uploading pictures to see the problem and also the growth conditions.
I'm watering once every 1 or 2 days (PH = 6.0). Not using nutrients yet
