Hello,
I bought HLG 550 RSPEC , which seems to be really massive light.
At the moment I have a bit small tent for this light - I was aware of that already when I bought it, but I plan to increase grow space in next crop.
The tent I have is:
3.2 x 3.2 x 6.5 (1m2x1m2x2m2) and I don't supply co2 yet.
I've decreased light power to 320W (I've watt meter)
And I wondering if is still not to much? I asking because seems my plants suffer for calcium deficiency and I just can't add more nutrients/cal-mag as I should be careful with EC in early veg too, so I can't add a lot of nutrients at the moment, but maybe plants need them because of light level ? I read that I should add more nutrients if have more light than I should? And maybe if I decrease the light the plants will need less nutrients in this stage? Is that making sense? What do you think about this idea? I have 5.7 PH, EC - 1 and using Canna Aqua set at the moment. I have other topic regarding nutrients and calcium deficiency - just want to ask about the light now here as I have a feeling that I should decrease a power a bit, but i am not 100% sure. What do you guys think?
