Deficiency Or Burn
GMSgrowsanswered grow question 5y ago
Your ph should be at 5.8 for veg 6 to 6.5 for flower. Your solution temp would be best at 62 to 68 to keep roots healthy and vigorous growth. Cheers friend

Brown/Grey spots on the leavesHey, I hope this is my last question for this grow :P I've noticed some brown/grey spots on the yellowing leaves, what could they be, deficiencies or sunburn? I'm still feeding the plant with nutes, but the next watering will be a flush, so I didn't expect discoloring before that5y ago
