Pk or no pk

I don't see any reason to change what you are giving your plants... they look extraordinarily healthy to me so why mess around with it? Growers are normally concerned with deficiencies in a plant but there are also excesses that can happen and would impact your grow. Excess phosphorus, while difficult to diagnose, will see the veins of the upper leaves turn yellow while the bottom leaves will have dark spots and curl... excess potassium can lock out other vital micronutrients - iron, manganese, zinc, etc - So my advice to you is to keep doing what you're doing, keep feeding what you're feeding - increase the P and/or K when your plant starts saying it needs those nutrients - IF your plant says it needs them... not before. Good luck!

not yet, wait until the buds form normally week 5 only! so i would say 5-6 weeks from now, but it is the time to boost your plant with nutrients growth and bloom at max dose then in 2 weeks lower the nitogen and increase slowly the bloom until week 7 or 8 depending how fast it develops being haze tells it will be long flowering and expected foxtailing
