Is to okey?

Hi Sorrowcz, LST looks great! Well done. All seem pretty healthy to me. Good job :) Quick question - are you using Biobizz Grow at all? I can't see it in your list. My understanding is that this is THE base nutrient and all others Biobizz additives are optional. I believe you can substitute the Fishmix for Grow during veg, which you are appear to be doing - no problems there - but you will still need to add Grow during the bloom period as they don't recommend using the Fishmix then. Which leads me to my next point - you don't need to be using Bloom or Topmax at all until you have flowers underway. I can't see any flowers in your photos. Only reason I'm saying all this is that I can see some of your leaves have lost their lustre in the 2nd to last photo (I think it's just one plant), so you might have a very early stage deficiency... possibly magnesium. I would personally ease back on the Topmax and Bloom until you see flowering in earnest, and maybe add some Grow if you have it (if not you'll need it for the flowering period anyway - at least that's my understanding of Biobizz! I'm planning on using them myself outside this summer, so I just happen to have purchased all of them this week, and read the manufacturers instructions, but I haven't actually used them myself yet). Good luck!
