So I found out yesterday I had an overfeed. Well, in reality I was having an overdose. Early in the morning I did some watering ph'd 6,5 and run-off was 5.3 and 5.5, on auto-bb and NL#5xHaze respectively. The auto is in a smaller pot which might explain a lower ph.
I immediately made a flush with my tap water (ph 7.8) until I reached runoff ph of 6.3 and 6.5 respectively. I was late to work so I wasn't able to make a calm, clean job. Instead I made use of my hose directly at each pot. I didn't had time to worry about chlorine because I'm only going to be back on Saturday. That was as quick fix as I could do.
Situation now is that the affected leaves did not recover, instead where there was those spots (oh so similar to P deficiency in the litterature) turned yellow and dried. New shoots are still healthy which is definitely good (somehow). Asked my wife to clean her up and take some pics.
What I learn from this experience and I can share with all reading is:
1 - check ph often (weekly at least);
2 - don't overfeed the children! Less is more;
3 - flush every month;
4 - use a clean soil (without added nutes).
5 - different types of N increase (nitrate) or decrease (ammonia and urea) the soil pH
That's it. Thinking I could use a ppm reader aswell...
