Looks like a cal/mag issue starting up or PH is imbalanced causing a lock up.

Deficiency
Spotted a deficiency on my AK 420 Checked on growweedeasy charts and Imo it's a cal/mag deficiency. I meticulously check Ph and runoff and she had the same treatment as my royal dwarf. Probably more hungry than the others. Just wanted to make sure, cal/mag deficiency right?

Hello fellow growers :D thx a lot Firstly, is the reason why my plants (especially cookies) are very slightly curling/folding at the ends of the leaves because the LED is too powerful?(Reason to be worried?) Secondly, should I start adding nutrients? Just 1/4 of Bio-grow for now?

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)
2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F). What could be wrong and what can I do for them?

New to hydro, first attempt. Does this look healthy? On second week of bloom transition. The lower original leafs have some yellow on them and brown dots. But otherwise any input would be greatly appreciated.

Phosphorus? Potassium? CalMag? What is going on here?
So in week 8 after flushing with EC 0.4 and giving extra PK 13/14 afterwards (EC 1.9) there are still problems occurring. I personally think it’s a deficiency of potassium and phosphorus. Can anybody give me some advice or tell me how to fix it? Thanks!

Yellow spots on leaves
Hi, I've noticed these spots on the leaves, does anyone know what they are please? Leaf Septoria? I hope not. It's a soil culture under leds, I used Biobizz products (Bio grow, bio bloom, top max) with biobizz calmag, I adjusted the ph to 6.5 with biobizz bio down. Thank you,

Help with unhappy plant
Started developing yellow/brown spots last week. Watering approx 2L every 3 days. Soil is HF/OF/perlite mix. Gave first feeding of FF Trio at 1/3 strength 2 days ago but she's continuing to look worse. More spots, lack of color and droopy leaves.

Dying leaves
I think it's a nitrogen deficiency causing me to lose some leaves earlier than I hoped, What should I carry on doing from now on? Last watering was 0.5ml/l of Grow, 2ml of bloom and 1ml of CalMag, just recently fixing a calmag deficiency after not having any(ran out).

Light burn
I've got what I think is light burn. I can't dim or raise my LED lights (300w), but I'm currently running them 24/0. Would switching to 18/6 help? Or would it help to take the burned plant and have it out in natural light during the day? I'm growing autos and they're flowering.

Light stress or Nute Problem??
Would this be a light stress problem or a nutrient problem? Seems to be only the ones on the top so I'm guessing lights but want to be sure.

bottom leaves yellow
Helloo So today I've noticed that the bottom leaves are yellow. I don't really think it is a problem since I think the reason is that they don't get enough light because are covered by the bigger leaves on top. But it's better to ask since I'm a newbie. What do you think?
