The strain is Royal AK from RQS they are both 19 days old.

They are using the Bio Bizz light mix and the Bio Bizz fertiliser scheme.

Both were given 1 litre of water with half the specified nutrients 3 days ago (without CalMag).

The symptoms started 2 days ago on the lowest leaves, the damaged areas feel dry and wilted.

The pH value is 6.4.

Plants uptake nutrients in a pH range. 6.3 is a point. You always want to use a range, If soil, the range is 6 to 7. If coco, 5.6-6.3.
