My Royal Creamatic has the edges of their leaves pointed down, loosing soil and some yellowing in the older leaves. I've tried to use google but there were many opinions about this. Have the feeling that I should just give ph water for now. Any ideias/advice? Thanks

Yellow leaves
The lower leaves turn yellow Is it due to a lack of nitrogen, or is it self-defoliation of the plant? (photos at week 5) I look forward to your advice) Should other leaves be defoliated or left as they are?

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?

Leaf problem and purple stems
Hi, I have a problem with my auto. I have purple stems and problems with the leaves. The soil contains organic nutrients and mycos sometimes I add flowering boost from royalqueenseeds so I don't think it is P or K problem. Is it a nitrogen deficiency ? Thank you for the answer

Yellow Colour
Some leaves have been turning yellow. Especially the lower ones. I thought it was a nitrogen deficiency as I didn't give the plant any nutrients till 2 weeks ago. Now I am feeding her with Biobizz nutrients according to their table. Should I be worried? Any recommendations?

Fan leaves turning extremely yellow late flower
Hello. Day 61 of flower, Green Crack 2.0 by Humboldt seed organization. Soil based. All of a sudden all the fan leaves are turning yellow. Trichomes are clear, no exceptions. Is it from finishing or did I mess up watering/nutes in the last couple of weeks? Thanks in advance.
