7 foot plant - 1 oz yield?

[Dutch Pimp]

misk you head the nail right on the head.I'am haveing the same prombles
and mind is about 7'2" tall and flowering now for 5 wks.salt build up wrong PH
too strong nutrs and yes NOT ENOUGH LIGHT. Flos is best for clones and seedlying.Green Man on pot tv showed me the way,flos for the start grow to about 12"and than HPS for flowering and the finish.I"am going this way after
this grow. Keep on tokeing

Weak light....weak grow.....400HPS Hortilux.....RULES!

i dont think it would matter how big the light is, if its the only light on a plant that tall it will suffer. running lights along the side would fix this problem tho, making the plant quite a monster, but haveing 3+ lights on one plant would again make it not efficient as u could have many more plants producing more bud in a shorter timespace.

its good to brag bout having a 2m+ tall plant tho

maybe ur friends plant was 7 feet because it was stretching from lack of light??
