Are you giving any nutrients yet? Coco coir doesn't contain nutrients so you need to start sooner than if you were growing in soil.

Seedling leaves are discolored and starting to curl
Not sure what the issue is here. You can see it evolving over the past few days (Sept 29th - Oct 2nd). The leaves are discolored, light, almost yellowish in color. And one is starting to curl. There are clear images of this in the post above. What's going on here? Thank you!

I have the light at a height of about 40 cm. The photo is taken immediately after watering. The water drains as it should. I use biobiz lite mix. I think it will be poor water quality or spoiled fertilizer. How do you recognize spoiled fertilizer?

Yellowing and dropping of leaves
Does anyone have any ideas what could cause the yellow and dropping of leaves for the Royal Jack. All plants are treated the same. The growth is stagnating as a result.

Spots on leaves
I'm still dealing with some spots that seem like cal-mag lock-out/deficiency but my PH is at 6.2-6.5. I think the light was too powerful I moved it up from about 16" to 18". I hope to have a lux meter soon to confirm any light stress issue. Still look like PH fluctuation?

Beginning of week 8. Deficiency? Nute lockout? Normal for this stage of its life?
Beginning of week 8 and her leaves are showing more spots and discoloration everyday. Is this normal for an Auto in the late stages of flower? Or do I need to feed more? Maybe a flush? This strain says she takes about 10 weeks start 2 finish.

Yellow bright new growth
New leaves on the Candy Kush plant #1 are bright green/yellow. This seems to have started when increased biogrow from 2ml/l to 3ml/l. Iron, zinc or sulphur deficiency? Only give calmag on next feed? Might have measured pH before adding nutrients so Faber wrong pH?
