Yellow/burned tips & curled leaves
I have an issue with some yellow/burned tips and curled leaves. I already suspect that mainly is from light stress but could also be a nutrient deficiency? I´ve raised the lights the max I can and keep it at 80% for 20 hours. Biobizz soil and nutrients. Thanks in advance!

Mancha en hoja
A que se debe que estén así algunas hojas? Es deficiencia o exceso? Regaba con 1000 ppm pero vi algunas puntas quemadas y color verde oscuro en las hojas así que lo fui bajando poco a poco hasta llegar a 500 ppm, y hoy note esas manchas(el agua drenada da 750 ppm)(coco y perlita)

Grower question
Any ideas what the issue could be? Few weeks into flower. Dealing with fungus gnats and have kept the population very low. Temps do get high, at most 95 (hot I know). I cranked down the lights to their lowest setting (100 true watts LED). I have adequate air flow.

Nutrient lockout, ph imbalance or nutrient burn?
Unfortunately I don't have a ph meter, so my best guess is one or more of these problems: nutrient lockout, ph imbalance or nutrient burn. The first 3 photos are from an Auto Northern Light and the last 2 are from an Auto Jack Herer.

Nute Burn Plan. Lower light to 24 inches and turn on bloom switch. Flush soil with 8 litres of water (PH 6.5) per pot. Questions: will increasing the intensity of light increase plants ability to absorb nutrients, or simply stress them more? Is 8L water/ 10L pot enough to flush?

Leaf damage and flower analysis
Asking for thoughts on leaf damage. I think there may be nutrient shock so I will be reducing PPM to 800 to see if that helps. I am confused by other problems seen on a few leaves. I also want to ask if I am getting close to harvest (check flower pics) since this is an autoflower

Yellow edge with brown spots on fan leaves
I am wondering if anyone could help me figure out what is going on here. She’s been healthy all grow, but in the last week has started showing the weird yellowing/browning on a few leaves. The temps, nutes and light haven’t changed really. Anyone have any idea what this could be?

Nutrient deficiency which kind and/or light burn?
Do I have some nutrient deficiency or light burn or maybe both? Looks like maybe P or K? I changed my light to a HPS and the plants grew much closer to the light so could be too much PAR/heat so I raised the light. I also had started to add Cal-Mag to my feed just before.
