yea, we told you ph and cal mag. Its not going to fix in a couple days, it will take at least 10 days after you use the calmag supplement to see any changes

i have said it twice and seeing as i'm posting again i might as well re iterate.

the plant is hungry!, that is why it looks like shit.

there is food stored in the soil, when the plant becomes too big for the pot it will require either transplanting to an appropriate container size or feeding with the bottled nutes you have. the soil is depleted so you need to supplement with the VEG solution at MAXIMUM directed strength. feeding with a complete and balanced plant food will ensure the best health as opposed to trying to rectify a problem by adding one or two elements.

if you are currently feeding full strength veg nutes every watering and you continue to see the problem worsen then discount my information but i am confident as can be that if you do that the problem will stop. and no those leaves will never ever be deep dark healthy green so try to concentrate on the new growth up top.

just add more base nutes.

i've grown a hell of a lot of weed and never once used cal/mag. if you are not using r/o water you definately should not need to be adding cal/mag to your mix.
!
So out of curiosity if you use R/O water then it will more likely be useful to add cal/mag?

there is a lot of calcium in most tap waters so you shouldn't need to add it to the mix. if you filter your water then maybe the lack of calcium may rear it's head but as i have great quality tap water i don't know too much about that.

for years i have read that coco growers MUST own a bottle of cal/mag but i have never even thought of buying one because i've never seen calcium deficiency, now magnesium def causes red stems i'm led to believe and i do see that quite often but i up the base nutes i use and it goes away.
