Use Ebson salt like teaspoon to a gallon to get your leafs to curl back down and then you need nitrogen

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?

browning leaves
Anybody have any idea on the cause of my leaves getting brown spots and curling at the tips? It's really just on the big mature leaves and leaves near the buds. Any smaller and younger leaves are still fine. Maybe a nutrient issue? Or is it just that its close to harvest time?

Nute burn?
I have one plant that's browning and tips are starting to point up. I'm thinking this is due to ffof soil being too hot for this one the other 2 dont seem to have problems, though another slowed down and is getting a little twisted. Anything I should do besides continuing ph h20?

Starting Training
I'm currently worried about my older plant set that seem to be constantly having the leaf edges curl and seem to be a little droopy and a little too dark green. Also I feel like I should be doing some sort of training. I would love to have some feedback on what you all think. ✌️

Why are some leaves curling strangely?
Hello everyone, the problems begin unfortunately. Why are some leaves curling strangely? I have not given any nourishment, the temperature and humidity are constant, will it be a problem of PH or EC? Thank you in advance.

Help diagnose hydroponic plants! Too much light/heat? Nutrient issue?
The plant's leaves on the right are wilting and drying out, while the leaves on the left are spiking. Just did a nutrient/water change but it didn't help, and it looks like growth is being stunted on the right plant. Humidity has been around 45-55 rh and temp 70-80F

I probably have spider mites on my plant. Yesterday I sprayed it with Maag oil. Today I bought an organic product and sprayed it on the plant. Are the discolourations on the plant caused by the mites or burns due to increased light from the drops? Or a lack of nutrients?

Leaves curling upwards
What could this be? I consider too intense lighting, could that be possible. Just transplanted a few days ago into these 1,7l pot's. Since it is the first time i use the The Mars Hydro TS 1000 for flowering i think i might have given the plants too much light.

Taco leaves (Desfran)
Hi, some of my leaves are curling like tacos (upwards). Some enviromental informations: day temperature 25 °C and humidity about 55%. At night 20 °C and humidity between 55 and 60%. I give them very only 1 ml/Liter of nutes (adcanced nutrients) and in the top rare purpish spots.
