I discovered that it was giving little "food", ahajahhah, I was impressed, this plant is eating 2.0 ec at this stage, of this size, really impressive, I was giving 1.6-1.8
20/02 1.9 EC - runoff 1.8
21/02 2.0 EC - runoff 2.0
22/02 2.0 EC - runoff 2.0
now they seem to be getting better
23/02 00:30 2.2 EC runoff 2.2
23/02 11:00 2.4 EC runoff 2.4
24/02 00:30 2.4 EC runoff 2.4
24/02 11:00 2.4 EC runoff 2.4
25/02 00:30 2.5 EC runoff 2.5
25/02 11:00 2.5 EC runoff 2.5
The runoff come the same of the watering solution, but 2.5 is showing some problems
26/02 00:30 1.7 EC defoliation
26/02 11:30 2.2 EC
27/02 00:30 2.2 EC
27:02 11:00 2.2 EC
28/02 00:30 2.3 EC
28/02 11:00 2.3 EC
01/02 00:30 2.3 EC
01/02 10:00 2.3 EC
