The plants look pretty happy to me is all im saying.
Dont know what your exp lvl is but most newer growers tend to kill with kindness
Can you get a bump in growth with more nutes?
Mabey.
I dont have exp with your plants or the medium or nutes or environment your plants are in
But i can say they look happy and not showing any blatant deficiencies.
In other words your doing fine dont KILL EM WITH KINDNESS
Less is always more because you can always add nutes much more difficult to chase a deficiency thats actually a toxicity from over nuting.
Hopefully this is helping im baked and way past bed haha ill check in tomorrow
