Continued with root juice at start of week. Quickly ramped up use of fish mix - should have increased strength in previous week; observing signs of n-deficiency.
Topped plant 1 and 2 and started light LST on both to improve flexibility ahead of tying down (once in final pots).
Plant 1 is particularly large, hungry and thirsty. Plant 3 is perfectly well, but smaller node spacing and less developed.
