Week Three slight leaf discoloration
In week three I'm seeing some slight discoloration. Not sure if it is something I should be concerned with. Using COCO, Worm Castings, ReCharge. Watering daily to keep the amendements active. Maybe I'm watering too much? Love to hear your thoughts. Thank you and happy growing.

On two of the oldest plants their first true leaves are turning a yellowish color and every cotyledon appears to be yellow now. Is this due to watering or too much light or something?

Should I harvest in 2-3 weeks ?
Hey, do you think my plants might be ready in two weeks ? They're autos in 7th week of their life. I know that 9 weeks is ok for most, but these should take approx. 11 weeks. Do you think one more week of feeding, then flush would be appropriate ? Trichomes are mostly milky white

Yellowing leaves help please (newbie)
Hi guys, had a calcium/ magnesium deficiency last week which I have treated with calmag this week However I’m concerned the plant is yellowing more. Is this still related to the same issue ? I understand the brown spots won’t be reversed but should the leaves still be yellowing?

Autogrowing
Do these look healthy? Thoughts? I'm new to hydro/growing
I have autos growing in a dwc system being fed half the regular amount of hydroguard, calmag, and grow/bloom. 1 plant is a week younger. The dark green plant looks like its leaves are clawing and has big brown spots on the leaves. The other has some brown dots and little yellow.

Nitrogen deficit?
The bigger plant is struggeling a bit again. After some talks and readings it could be a nitrogen deficit but am not really sure how if I should react to it, since the need of the plant should get less for nitrogen in the next weeks. Please read my journal for more information.

IMPORTANT excess/deficiency? What's happening? Flowering is in danger
What's happening here? I think it could be Fe deficiency, Mn deficiency, S deficiency or maybe K excess. But I'm not sure about diagnostic and I think I can have more than one problem. Please help, I don't know how to solve it and I see how flowering is very slow and weak
