My ph is 7.5 on one of my girls and leaves are turning yellow. Soil is coco noir. How do I lower the ph?
Humidity in the tent is consistently 35%. Is this good, bad, indifferent?
Humidity is good as for first question pH should be lowered with acidic items aka viniger citric acid or the preferred method of using a simple pH down solution after you add nutrients welcome to forum
Humidity is on par for flowering.
Do you have any pictures to better assist with the yellowing?
What are you using to check the ph in coco that is way high
You need ph5.8 ish
Coco Coir is not “soil” and ph should be lower, 5.8 is good target. Think of coco as a hydroponic medium rather than soil and you’ll have better results.
35% RH is great for flowering. Not ideal for veg, but still very tolerable.
pH for coco should be treated as a hydro grow with pH between 5.6 and 5.9. Nutrients will lower pH over time, but you should really correct it and maintain a proper pH now. Suggest pH Up and pH Down (available on Amazon.)
You had the light too close at one point, but the top growth looks great. Whatever you moved the light to, looks good now.
Thank you. Just ordered ph up/down
She looks like she’s already moving in the right direction
