Still signs of yellowing and burn tips
Reached out to FB hydroponics group and some suggested to increase the nitrate.
Data looks strange too. EC is still above 1200. Pen problem or EC of the whole system affected by earlier addition of CaNO3 and Epsom salt.
Recalled that I have been adding mainly AB lately. Inbalance caused by lack of C. However many mentioned that A and B is enough. 🤔
EC1488
pH5.90
WT29
Water level: just below mid level.
Added 1L of water with 10mL AB, 20mL C
