Looks like a Nitrogen deficiency, but I would start with checking your pH.

Yellowish color at the tips and wrinkles My plant has been yellowing for a day now, I think it is a deficiency of some nutrient but I don't know what it could be, I have thought about buying NPK. At the same time, there are also a couple of leaves that have slightly wrinkled the tip and have been half lowered.

Is this a deficiency?Hello there, Today I saw that some of my plants have some curled and sad looking leaves (see pic). The soil is pre-fertilized and I currently use normal tap water (p.H. adjusted) for watering. My plants get 18hrs of light a day (approx. 300-400PPFD) Thanks for you help guys :)

Fading bottom leaves Bottom leaves faded in color over the weekend and have started to turn yellowish. Is this a simple nutrient deficiency or something else I need to be concerned with?

Nutrient burn/deficiencies/feeding Having difficulties with a few of my plants, I didn’t add any nutrients until they were close to 30 days old. And then only cal-mag at what I thought were low doses. One of mine has lost almost all leaves. What would you guys recommend moving forward? I have almost all fox farms

Deficiency?I'm having trouble identifying what's going on here, is this a cal-mag deficiency, iron or something else? Seems to be yellow spots with some brown and a couple holes here and there.

Nutrient Burn, Leaf Septoria, Nutrient Deficiency? Or something else?I have been having issues with the Purple Haze. I've tried adjusting the Temperatures, adding additional Cal-Mag, changing lumen intensity etc. I believe this may be nutrient burn? Added an old image of leaf before mainlining, the plant is 1 week old after mainlining was done.
