MedUs_0oanswered grow question 5 years ago it may happen that some go slower than others, as I see it is growing a lot in height and therefore in my opinion and for this, the same thing happened to me, saving a week or 2 more than expected, but in the end a good collected, not so the size of the vase but in my opinion those also influence. always keep an eye on the pH, but I tell you to be calm and don't worry, a little patience and you will see that in the end it will be worth waiting even an extra week. if you want you can take a look at my (royalgorilla) at 8 weeks it looks more or less similar. I hope I have been of help and wishes you good luck.
