Not a deficiency, but nitrogen (over dose) burning.

That looks like PH problems coupled with over watering and a slight nitrogen toxicity! Feed your lady some light water feeding at the 6.4 range for a week! Good luck ✌️🏻💚🌿💨

Check your soil, plants will throw some crazy looking deficiencies if it's over watered. If you are sure you didn't overwater the plant check your pH.

Potassium or magnesium. Might be a touch of both actually. Is ph in substrate or Reservoir correct? Ph tool calibration done regularly?

Tips of leaves turning
The tips of leaves are turning up a bit. I guess they are doing that because of high temperature, but could there be any other reason they are doing this?

Cotyledons curling upwards - the others didn't do this? :(
I'm not sure what's going on! The two others didn't do this. I'm using ViparSpectra XS2000 at 24" distance and 50% intensity.

Brown spots and yellowing leaves.
I’ve just started to get these brown spots and yellowing leaves on the top leaves of one plant. Not sure what it is, potassium or calcium deficiency. Soil ph is 6.35. Water with regular nutrients at a ph of 6.5.

Leaves curl on upper new growth and mid but not lower.
I’m using the canna coco line except boost, looks like phosphorus deficiency. I just lowered my a and b 0.7 ec and added 0.3 of pk for a total of 1.0. Is this phosphorus deficiency and do you think my changes will help. Leaves are a little dark shinny and the shape is odd.

Discolouration of some leaves
Is the colouration of these leaves someone to worry about? She’s a young, 2 week old Wedding Cheesecake auto and I’m new to growing and just want to make sure she’s ok! She’s growing in a 70/30 split of coco and soil and has only been fed water so far! Is it nute time?

Nutrient problem??? Excess or deficiency?
What do you think is the leaf issue? Open to second opinions. Most everything stayed the same, except: > increased water: 2L to 3L per 7 gal of soil > introduced a bloom booster > increased volume of worm castings, molasses, mycrobes and ethylene to the tea

What went on here??
This is an Orange Sherbet I grew in Happy Frog with the FloraGrow series. I harvested early because I thought the plant was dying, and couldnt seem to stop it by flushing. Does this look normal for a plant being flushed out? Should I have waited?
