light (hps 400 w) is 15 inches from plants - got a fan working the heat

feeding nutes once a week

temp 22 degrees celsius

.. but i think i figured it out .. its the ph, its to low - I look at the bottle which contains the liquid used to balance the water - and it says ph 5.5 on the label!! i held that bottle in my hand almost everyday for the last two months - and I did not notice until now! what a waster - anyway - ran to the shop - got baking soda..

gonna try that

on the whole - the plants do look rather healty..
