I have been out of PH-buffer-fluid for a few weeks and I have suspected that the calibration on my ph-meter has been a bit off. But today when I finally got to calibrate it again I was a bit shocked. When i put it in the 7.0PH solution the meter read 8.1!

I have been adjusting the water to about 6.2 (according to my faulty ph-meter) since I suspected it was maybe 0.2-0.3 too high. But it turns out it was actually way more off tthen that. So this means my poor little girl has had to work with very low PH for quite some time now.

Im glad I found out about it now anyway. What would you guys recommend me to do at this point? There is about 40-liters of Coco in the "pot" and I usually water it with 10 liters at once. Think I should flush abunch of water through it with better balanced PH?

After I calibrated it today and checked the runoff it was at 4.7. I am surprised she looks this good with that low PH. Anyway I have now poured 30 liters of 6.5ish PH water through the coco and the runoff still reads 4.8. The plant is in 40 liters of coco. It is a pain for me to flush correctly since I just have a very shallow container to collect the runoff and I then pump that out with a handpump.

Hey man! To bump the ph up i would maybe ph your next run with a little food at around 6.5 ish, and then check runoff..... a bit of food will help things buffer, the chemical reaction will help break those acidic salts down. 4.7 is quite acidic even i'm surprised you have decent health! You don't need to go too far in my opinion. I've seen Coco work wonders at 5.5 always a good flush with neutral water at harvest and all sweet ;) looking great man! nice closet grow!! subbed to see this one out!

Thanks for your reply! I still can't seem to get the PH up to a respectable level. I have poured a few more 10-liter jugs of 6.5PHed water with nutes through the coco, but the runoff still reads 5.0. Atleast it is going in the right way. Hopefully it will be 5.5 in a few days if I keep doing this.

DAY 23 FLOWER:

The actual plant is pretty large, I agree. But the buds just don't seem to take off. They are still really small after 23 days of 12/12. I wonder how much of this has to do with that they had to work with very low PH for over a week. Anyway, here are some new pictures:
