I noticed that some leaves have turned yellow due to a lack of NPK. I'm halfway through the sixth week and I'm only feeding the plants with Biobizz Top Max. What do you think if I add a bit of Biobizz Grow??? Thanks in advance!
I use the biobizz program too, indeed they are a bit dull, pale, use bio grows 1 ml per L until the end and there's also bio bloom normally before TOp max. Biobizz chart available online with details by week.
