Think my temps are okay. 24-30C (average 28C) in veg and 21-27C in flower.
Good to know it's not just me that's got reddish cheese. Thanks
Red stems can be a genetic trait. However red leaf stems and stems can be a sign of a potassium deficiency. If you have ruled out temps that would be the most likely issue if not a genetic trait.
I have had red stems and leaf stems and a feed on Bloom sorted it out. It was returning just as I fed again. The strain is Haze and also appeared on Northern Lights - both in current grow. Temps were not low.
Be careful not to misdiagnose though - how 'red are they'?
Lack of Phosphorous will cause plant veins to turn red - usually happens in flowering...what stage u at?
Good luck mate.
