literally signed up to this site just to be able to comment to because it seems ur grow is going on so nicely and i hope u dont keep adding nutes because the yellowing tips of the leafs!!! thoese are sign of "nute burn" and typically too much of nitrogen(yellow tips) and i think its too much calcium (the slight lighter discolor in between the veins of the top leas) and also the veins of the leafs and the backward cupping of the leaf edges all point toward nute burn and possibly getting into "nute locking". u could know the difference where when stuff is lacking from the plant the yellowing will start from bottom up and when it is too much nutrients than it will burn and yellow and dry up("nacrosys" "and "chlrocys") from the newer top leafs downwards.- thats why im saying ur plant is looking very nice cause keeping all the first and bottom leafs so green and alive is not something every grower is doing! mostly at this point most growers lose a few leafs per plant. lloks like u lost only the first two leafs around week 5 (which is normal and how a lacking nutrien dead leafs looks like) and from then on ur plant seem to be getting darker and fuller of food.
id suggest try to go for only water for a week or two mate. weed really dosent need 3 different typed of N P K sources and not at that high rate.
good luck and nice grow by far mate! keep up the nice work and have fun!
