Help with burned leaf tips

Concisionstarted grow question 6y ago

The tips of some of the leaves have begun to dry, curl, and look to be dying (see pics). I think it's some sort of nutrient burn, but I'm unsure. I water every other day w/ a solution of Miracle-Gro 24-8-16 at 50% recommended concentration. Used distilled H2O last 2 waterings.

Guess on what this is?Unsure what this issue might be. PH seems in check going in and out. Getting mainly Fox Farms nutrients - got very weak doses of B-52 and CalMag a week or two ago. The other two plants are fine.

Leaf problem My leaves are looking strange? Can this be because the leaf hasn't fully unravelled/grown fully yet, or could thus be heat/nutrition. Added 2x pictures to see clearer 😁

Gorilla Cookie Week 8 I will try to keep this short, but my Gorilla Cookie autoflower has some problems. The tips look like they are burnt or dying. I use living soil, so I didn't really give my plants any nutrients except worm humus a long time ago and BioBizz Top-Max yesterday 3ml/L. See my diary

Excess or Defiancy?Some leaves from the top of my biggest plant, Frisian Dew, turn yellow and brown. The others don't show this behavior. The plant is in week 22 and still needs approx. 4-6 weeks until harvest. The plant pot is fully rooted up to the surface.

Nutrient Burn?Too much N? Oldest leaves are affected generally although some younger leaves showed burnt tips. No obvious clawing. Temps have been somewhat lower lately around 25. Fed twice @ 1ml/l of Biobizz fish mix. Decided to flush with straight water just in case.
