Auto flowers blooming ph

Just checked the pH of the run off of my girls and it came in at 5.6-5.7. Do I need to get this number zeroed in to 6-6.2 for optimum fat sticky buddage? Everything seems to be growing well and the buds are coming on with loads of white hairs and already getting frosty on the little bud leaves.
They have been budding for 21/2 to 3 weeks.
I’m growing in soil (Fox Farm Ocean) with added perlite.


6.5 is your sweet spot and 6.3 to 6.8 is an appropriate range. 5.7 is too low and can lock out phosphorous, calcium, and magnesium. Some growers like to maintain 6.5 to 6.8 in flowering to maximize phosphorous uptake.

Pictures always enable us to give more accurate advice and everyone loves bud porn.


Thank you my brother :smiley:. They are looking good so far, I want to tweak the pH so the buds reach their max potential. I’m at around week 3 of flower, so I should have another 3 or 4 weeks at least before harvest. Right??? Plenty of time to adjust the pH for optimal nute uptake. As soon as I can, I’ll start including pictures with my queries. Waiting on a USB microscope from everybody’s ubiquitous friend Amazon.


You have 5 to 7 weeks to go yet. It takes 8 to 10 weeks of flowering for the buds to ripen.
