Hi, low grade heat stress. Nothing to worry about at the moment. Shade your pot, this will be sufficient.

Starting to fade? Or nutrient deficiency?One of my plants has several fan leaves that are turning yellow/purple, and I can't tell if it's low on N or starting to fade. The plants are 2 days into week 5 of flower with a 9-10 week flower period, so it seems a little early for it to be turning colors like this.7mo ago

So a bunch of my babies are getting this extreme leaf curling. It happened when the lights were off for only like 3 hours. Could it be windburn or Humidity? Nothing is out of whack in the Grow room temps were under 80 and humidity was >70 because I have a dehumidifier. ThanksWeek 3

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?2y ago

What could be causing this?I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far.
I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout.
Anything else it could be??5y ago

Heat stress. LED light 2.2 ' away, raised the light. ( curling up )
Late stage P deficiency... green veins.
Can't flush, was just waterlogged, what to do? Water a bit with RO?5y ago

What to do with crispy curly fan leaves that do have some resin on them?, I'm already on flushing.Some fan leaves are starting to look a bit too crispy and curly, they do have some trichomes, I'm 3-4 days into flushing.
I'm not sure if the dry matter can "contaminate" the buds somehow, and don't know if I should do something about it, I'm planning to get some "bubble hash"4y ago
