whitw widow from regular seeds ( barneys farm )
600 watt hps

soil from hydro store !

ph 6.5

RH 60 in the dark 50 when light on

tenps 68 in the dark 77 when lights r on

water/feed/water/feed

had this exact problem at the same time as last grow ( same seeds ) last grow i did not exceed 50% nutes and when they yellowed i backed off last time as they had tip burn,, this time i av done the opposite and got the feed upto 100% but dont think its helping, waterd with some epson salts yesterday and foilar fed the worst one with some E.S i will see later if any diference !

they were veged for 4 weeks from seed and now they have binin 12/12 for 33 days !

not growing this widow again but would like to get these to the end any tips will be well appreciated ! thanx !

the first pic is ten days ago the other pic with the yellow is 2 days ago and looking worse by the day !

full size pics in post further down the page !

lower fan leaves can yellow and die off as the plant progresses through the flowering process anyway...even though you are using a 600watt HPS it still cant get through 20 leaves stacked up. I can't get the pics to go bigger to look closer, I would just trim them off, your growing conditions seem excellent.

probably a silly question but what is your ppm ? i know i cant use my tap water here because its way too hard ... and from the little i can see in the pics they look just the way mine did when i used tapwater .. i would say use some calmag or something like it .. made a difference for me but like massah said could be just low penitration of your light ... sorry couldnt be more help

I can't really tell m8...too small...only thing i can notice in the 2nd pic is the leaves look droopy...overwatering? The plant size vs the pot size seems a bit disproportional...so if your soil drains too much, and the root system is starting to get rootbound, and you are overwatering, it washes the nutrients needed out a bit, so its not getting enough...how large are those pots(again hard to see from the pics) :)

aye larger pics...i'd go with pots too small and overwatering, undernuting...I'd almost go to a feed/feed/water/feed/feed schedule...shes flowering vigorously...she wants nutes!

ya no i thought my water was ok coz this is what my best WW looked like ten days ago though now she is goin yellow all over only seems like all the fans though as the bud sites and the foilage around them are very green still !

this pic was taken ten days ago at 3 weeks into 12/12 ( wished she looked like that now ) so if it was my water i wud think i wouldent get them that healthy which is y i think its maybe somethink else m8 !

now all the fans on this at the top aswell r yellowing at alarming rate !

Maybe just a simple Nitrogen deficiency, need better pics.......I see the pics, yep looks like a basic Nitrogen deficiency......
i thought it was N def but there nutes r upto 100% increased themslowly through the grow and even used veg nutes 2 weeks into 12/12 then went to flower nutes 2 weeks later this yellowing started from bottom and is now all over the fans but not the bud sites !

so at this point you've only got two options...repot to larger pots, or just start feeding it more, hell you could probably feed it nutes every time and not do the feed/water/feed/water schedule.

supose i aint got much to loose by feed/fed/water/feed/feed aint got the will or the money to pot change, coz i will need 3 pots and a bag of soil from hydro shop so will go with more feed see how it goes, again thanx for ya input !
