She is taking shape nicely, but in the meantime I noticed some CalMag and N deficiencies too. On the next feed I will go with 2/3 strenght and the following one will be 3/4 if needed.
At the moment I’m switching from tap water to rainwater, the problem is that Biobizz PH down doesn’t hold the ph for more than an hour. Hence the deficiencies.
I ordered a PH- from Growth Technology, it solved the issue.
The watering regime is as follows:
•Clean water in the tray for 3 days, top up if needed
•Turn off the air pump, drain the water
•Wait 12 hours
•Pour the feed in the tray (4 liters - 1/2 strenghth)
•Leave the feed in the tray for 24 hours, air pump off
•Drain the leftover of feed
•Clean water in the tray, turn the air pump back on
