New Grower No idea

[gregie420]

So on one of my white cheese plants there are a couple fan leaves that all of sudden are turning dark green to brownish and dying at the tips, i'm not exactly sure what is going on, all i can think is i have a warm mist humidfier in the tent and the leaves may have gotten into the path of the hot air coming out. Anything info would be much appreciated. thank you ahead of time to all that respond

Hey I'm a bit of a noob but few questions.
What lights you using? Strength of nutes and what nutes? Dark green leaves sounds like nitrogen toxicity unlikely though. Dying brown tips sounds like nute burn. But as I said I'm a noob myself so hang in there and somebody else will be along soon

I'll second the possible Nitrogen toxicity with the dark green. What soil, and nutes and how much have you fed? How old are they?

i could of burnt them, there under 400w hps, i dont go over 600 ppm and every other watering for nutes. i thought if you had nutrient burn you get white tips, but i am no pro haha

there just about 8-9 weeks old, buds are looking amazing, everything else on the plants looks very good also, just 3 or 4 fan leaves have it going on and kinda in the same general location thats why i was wondering if the steam might of done it

I use fox farms ocean forest soil. fox farm nutes and micro nutes for flowering, usually every other watering they get fed. they are in 3 gallons pots, im trying to think of everything

Alright. No clue why I didn't ask this first, but we're gonna need some pics yo! Under natural light preferably. Then we'll be able to tell a lot better what the issue is.

ok, ill try to get some up tonight, if not tonight for sure in the am

Cool, if they're finishing up(since you're at 8-9 weeks) then just feed plain Ph water from here on out.
