Help me diagnose this color on my leaves. I don’t if it’s something to be concerned about I just don’t want it to get worse. Overall I think they look great. What do you think?

I believe you are experiencing ph fluctuations. I'd calibrate your ph pen if you use one, if not I would recommend one.

They look ok. I would say 2 things, too much nitrogen and not enough pk, correct these and you should be fine going forward

I have black spots and burnt edges on a couple leaves. Some of the leaves are also curling down which I'm guessing is too much nutrients.

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)

Leaf problems.
In the last couple days, the plant that has been doing the best is now having some dried out, crumbly leaf tips. It is not undewatered. Has it just got through all the nutrients in the soil? The roots are very healthy.

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

It got a little hot yesterday I think plants hit around 81 at one point when I was gone. Not sure if this is some heat stress and light burn or if it’s a nutrient problem. This is this only plant and only leaf with any signs of this

How do you harvest in hydro (drip system with a tank) when some are late ?
Half of the plants are late (chlorosis, iron toxicity, nitrogen overfd) on a scrog net. As individual flush is impossible, I guess I have no choice than having different batches of ambered trichomes ! And I thought about different strains next time, sweet dreams...

Yellowing lower fan leaves, a few red stems; N/Mg deficiency or normal low leaf die-off?
Is this a Mg or N deficiency or are these leaves naturally dying off? Showing on only one of two plants so far. Appears only on lowest fan leaves. F20, 7L pots BioBizz AllMix and nutes (1mL/L Grow and 2mL/L Bloom). Temp/RH are good. Can't measure pH. Local soft tap water 7-8pH.

Yellowing/purpling leaf tips outdoors
Im experiencing yellowing/purpling on upper canopy leaftips of my outdoor organic cannabis plant in week 2 flower. I'm feeding via compost+dry amendments so over/underfeeding is unlikely. What might be the cause? nutrient lockout? Relatively low temperature (57-75F)? pests?

Getting out of the ideas - VPD, nutrients or deficiency?
I'm getting out of the ideas as the foliar symptoms proceed. Lowered EC down to 1.8 from 2.2, pH in range. VPD is getting problematic as the plants seem to be respirating a lot during the day and it rises tent RH sometimes up to 70% - exhaust duct fan wont keep up. Temps 22-24C
