So my stretchies look like they are starting to die. Growing outdoors, they are currently in 5th week of flowering, new growth seems healthy on two plants, but starting to die in the third. I don't know what to do - leaves are dying in 1 other plant and only starting to turn pale green in the third.

ah crap - realized the pics are rotated... don't twist your neck lol

You might not be giving it enough micro nutrients or basic nutrients... You also might not be watering enough, how hot is it? What soil do you use? What nutrients do you uses and whats the NPK ratio? Need to know a lot more things man.

Using a generic soil from a friend (don't remember the brand, etc, but his plants are always supreme). Mixed in some pearlite/vermiculite and am using a generic 10-15-10. Perhaps I have a P difficiency? I am thinking maybe too that they get TOO much water - they are affected by our sprinkler system - we typically now get day time temps 75-80F and night time temps of about 60F...

you need more nitrogen and other nutrients. If im not mistaken you need something more like 21-14-7 not sure if thats precise. Anyways I believe you need more nutrients. That looks like a big plant and its trying to produce a shit load of sweet n delicious nugs, but it doesnt have enough nutrients so leaves are dying off.

Yeah, you need more N. Usually N starts from the bottom up, but if you examine the plant you can tell that its effecting one of the higher nug's bottom fan leaves. It probably feeds the plant nitrogren in sections during the flowering phase, bottom foot is the first section, second foot is the second section, ect. It could also be a micro nutrient problem, but more then likely a N deficiency.

thanks guys - is the best way to increase my N levels simply to switch ferts to something like a 21-14-7 like beginner suggested?

Well - I was only able to find a 28-10-10 locally - do you think this will suffice? I don't want to just try something and end up making the situation worse.

Anyone care to chime in? Whats the best way to increase N levels - simply switching to a higher N ratio fertilizer?
