Light/heat stress most likely! I had a plant taco before because it was too close to the light. ✌️🏻💚🌿

I had this issue about week 4/5. I figured for me it was heat stress. What’s the humidity and it could also possibly light distance.

Is this Phosphorous deficiency or overfeeding?
It happened from day to night, the watering with Fish-Mix and Bio-Heaven was made days ago. Otherwise, I haven´t feed her any bloom nutes yet. Peace ✌️

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.

Wind burn??
What else can cause the leaves to taco a bit like. Light burn. Just a couple here and there?? Could it be. Wind I've noticed I had a couple leaves claw a bit but only a couple there too and only on the leaves that was moving the most. ?

Brown spots, serrated edges curling up - calcium deficiency?
This is a Barney's Critical Kush auto that's at about day 57. She's into flowering, but I've just started to notice some brown spots on leaves with some slight tip browning, and the serrated edges on the leaf are curling up. Is this just a straight calcium deficiency?

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.

Crispy leaves?
Crispy leaves developing as it flowers. Seems to just be those that had some spots from what appeared to be a magnesium deficiency. I hit it with cal-mag and the spots stopped but recently the most affected leaves are shrivelled. Only maybe 4-6 leaves right now.

Qué podría ser? Bloqueo de nutrientes, sobre fertilización? Cómo solucionarlo?
Hoy lavé raíces pensando que tuvieran un bloqueo de nutrientes. Creo no están sobre fertilizadas, pues las hojas estarían de color verde más oscuro y duras, como si fueran plásticas. Y éstas están caídas, algunas blandas y con esas puntas amarillas. Algunos tallos están morados.

many problems with the leaves
the leaves have been turning yellow and falling faster and faster, especially those below; the upper ones curl and become burnt with dots and turn yellow should I try to put the lamp higher? (I haven't given fertilizers for a week)

Let it grow or cut it out?
One of the seedlings isn't doing so hot. Should I just start a new seedling in it's place or give it more time? I've had a stunted seedling like this before in a previous grow and it ended up yielding a lot...
