Last week I removed several leaves that dried out. Overall the plant is suffering from light exposure and now I have reached the maximum height for the lamp in the tent. The plant did not grow this week staying around 62cm. I found some roots on the surface and covered them with more soil. I have noticed no substantial changes in the buds and I am not sure whether the general dryness is affecting them. I have purchased a ph solution to tackle that issue hope not too late. I am still confident I to get a decent outcome in a couple of weeks.
I saw that in the 7 week you showed a ph reading of 9.5 if that reading is true your ph is way way to high and is the cause of the driying process you are experiencing.
Have a nice grow mate
Thanks for your comment. I did some research and I finally decided to re-calibrate the tool. Now i have measured it again and the ph is 7.6. Now the dryness might be explained by two factors: light exposure and/or excess of nutrients. I will not add nutrients as i will have to harvest in a couple of weeks, light cannot be places in a higher position unfortunately. Will try lst next time :)
My Orion was also quite slow in the beginning, because I kept it outdoors in September and the first half of October. But it grew to 80cm within the first three weeks of flowering, so no need to worry!
