That is generally a symptom of heat stress, try lowering the temps if you can.

Upward Curling Brown Leaves/Nutrient Lock Out?
I've got a serious issue. Started 3-4 days ago, right after adding nutrients and increasing light. Leaves are curling upward and browning. Not crumbling yet but look like they will be soon. Both new and old growth is being effected. Maybe the Mineralized Phosphate was too much.

Necrotic spots
The last day or two I’ve had a bunch of necrotic spots pop up on the lower 3 sets of fan leaves. She is at node #5 now and starting to put out pistils. Is this phosphorus deficiency? I changed the res as it was close to a week anyways. Thanks all for the help. Happy Growing!

Organic soil 0.1-0.1-0.1 60% soil 40% perlite soil is pretty damn dry on top
The girls seem to be doing ok, little bit of curl up on some of the leaves, which indicates I over watered, humidity is usually 40-50%. I water 1 time per day with a mister, it's only been last few days that leafs curl up. Is it time for nutrients?. They are 10-11 days old.TIA

It looks like my plant is dieing! Plants turning brown after intense watering period
Did I drown my plant? Stress it? I gave a lot of water in a short duration of time, and now 7 days later she is looking terrible! Read my diary on week 17 for more info!

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?

Leave issue
What is this? Nutrient burn, deficiency, fungus? I tried to look up the answer but it might be different things on different plants. Please help me diagnosis this. The white powder is DE and the small holes are from flea Beatles. But I’m more concerned about the browning.

Light burn or nutrient issues? Female?
Does this look like light burn and maybe a lack of nutrients? Also can someone confirm that she’s a female or is it too early? I am first timer and think I see her lady parts already.

Weird or no?
Is this seedling looking weird? Some edges of the leaves are like sticking up. Then, I look to see what I thought had been a chewed on leaf. After taking a closer look though, i think it just grew in like that. All of the other seedlings are looking really good

Nutrient deficiency or surplus?
Hi Guys will post a pic shortly. Have to update the grow as we are actually heading into week 6. One of the white widows is a fair bit smaller than the other. And is showing some form of difficiency or nutrient burn. I think it may be due to to little phosphorus. Opinions?
