Yellow leaves

Splifterzstarted grow question 5y ago

Hi All, I'm at 9 weeks with Auto Night Queen, leaves have turned yellow for some reason. Lots of bud sites but all seem a bit small. Light cycle 18/6.Been feeding calmag on each feed. 1.5ml pk14, 1ml calmag, 5 ml terra flores every two litres. Would you say this is correct.

Lower leaves turning yellow and getting crispy Lower leaves are still turning yellow/brown. See photo. A couple weeks ago I got a greenhouse to protect the plant from the rain. Outside temperature has been lower and there hasn't been much sun (mostly clouds) so I don't think heat is a problem anymore. Don't know the pH. Help!
