I started those in 1/4 litre pots in a All mix soil/ worm castings mix 90/10 a few months ago, 3 months to the day to be exact. But I re-potted them into 5 1/2 litre pots just before I switched over to 12/12, same soil mix. And Ive just been winging it with the fertilizers. I use that Dutch Biobizz, range Root Juice, Grow, Bloom and Topmax. I started my Bubble Gum at the same time so they get a very similar mix which is @Week 4
Per 1 litre of ph corrected water 6.2
1 mil Grow
3 mil Bloom
3 mil Topmax
I will start week 5 with 4 mil of bloom and 4 mil of Topmax per litre but I use the Grow more sparingly. The plant's still look green enough so I will keep the Grow at 1 mil per litre, for now.
There's probably not much nutrients left in that soil now, might as well be coco. I water them from a tray below mostly, about 300 mil every other day.
What do you think?
