Deficiency or Whats the craic?

Seandawgemousstarted grow question 4 years ago

Can anyone tell me what they think is causing the yellowing? Is it nitrogen deficiency? PH? Should I be worried or what d'ya reckon? Any help greatly appreciated.

I would say something like a mix of nitrogen and lesser Phosphorous deficiency. Are only the bottom leaves getting this or is it spread over the whole plant?

My guess would be magnesium deficiency from the pictures. Give her some calmag for a few feeds should help.

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?
