Black spots?
Is this a deficiency, nutrient burn, or disease, growing in MG soil, recovering from overwatering as well.

Brownish stains after transplanting
What do you think this is? I have recently transplanted it outdoors. These stains appeared the day after. Might it be sunburn? What can I do if that’s the case?

Vexatious yellowing I can't get to correct.
This Northern Lights auto is being vexatious...I can't get rid of the yellowing towards the bottom. Not overwatered, I've tried beefing up the nutrients, etc. with no effect. Any thoughts or do I just writing off as she's just being a jerk? Other plants in this grow are fine.

Should I cut the dried leaves at the bottom?
Should I remove the dried leaf in the bottom? I was thinking that it might redirect unnecessary energy to the plant since the leaf might be too far gone to save. I was thinking of starting topping next week as well, when the fifth node start to show more.

Leaves are getting yellow and burnt
The leaves are turning yellow with some chlorosis on the edges and in the middle of the leaf. Anyone knows what causes this and how to fix it? She didn't get any CalMag until last week and I didn't add any high phosphorus and potassium sources to the medium.

What's wrong with my seedling?
I don't understand why there is something strange in the leaves of this seedling. It happened to me for the first time, even though I was always raised in the same technique. As a fertilizer I just added 0.5 ml to 1 liter of biobizz grow.

Leaves turning yellow/pointing up, stem turning purple
Having a problem with one of them.. all the leaves have gone very yellow and are pointing upwards. The stem is also very purple now. Any ideas what this could be? Other than a feeding of bud candy and watering here and there it hasn’t gotten any other feeding. Thanks!

Underwatering Issue or something else?
I haven’t been tracking exactly how much I’ve been watering. I usually water until run off. I’ve had to water daily because the coco loco has been drying out quickly. Is the yellowing seen in photos from 4/28 due to underwatering? I’ve been pHing between 6.2-6.4

Please take a look at the last photo of week 10, the close up of a cola. Does this appear to be the start of a K deficiency? There is tip burn on some of the plant as well. Refer to my notes with watering issues for past 2 weeks. All nutes listed ph ppm are correct. Thanks!!

Yellowing on dwarfed Stoopid Fruits
I'm having issues with yellowing leaves again. I have used Cal / Mag as suggested last time and have transplanted it into a 2 gal bag. I have also had a bit of browning around top leaves on larger plants but assume the lights were to close. Migro says 6" from canopy.

Yellow tips on newer leaves. Nutrient burn or something else?
I have noticed yellowing on the tips of newer leaves that seems to be slowly getting bigger. Nothing on older leaves. Start of Nutrient burn? I also have noticed some yellow/brown spotting on older leaves but that may be related to earlier PH flux that has since been fixed. TIA!
