3 weeks till harvest and big fan leaves yellowing pretty bad!?!?

[arrozkongandulez]

hello people, i have this monster blue widow plant she is 33 days into flower, DinaFem advertises it as a 55 day plant so she has about 3 weeks left....

so she has 24 main colas ranging from 6-10 inches tall.. they are big but they are not supposed to fatten up until the last 2 weeks according to the breeder..


anyway, about 15% of all the big fan leaves are yellowing pretty bad..... some of them are almost completely yellow... and some of them are starting tp get blue spots..

ive seen pictured of BlueWidow in full bloom and ive seen the blue leaves but the yellowing im not sure if it is normal..

she is in a DWC with about 1200 - 1500 PPM, she has NEVER given me a problem and she has never sufered any stress.... should i be worried? should i add veg fertilizer? or should i just keep doing what im doing.

ill try to post pics later since my HPS lights are on is kinda hard to see the leaves.

Yellowing in late flower is sometimes normal but could be a deficiency or light bleaching too. Nobody will really be able to help any without pics.

3 weeks is stilla fair amount of time, as long as the plant still has plenty of leaves to process light into food it shouldnt be a huge deal but if its spreading rapidly you will want to correct it.

make sure your not locking out N and if you have to get a little N in there and see if it helps. i wouldnt go apeshit crazy with it as the plant isnt using much right now but if your in a 10 gal rez and it calls for 5ml per gallon just do 45 ml of bloom and 5 ml of veg nutes and see where that takes you\


disclaimer, im not really a hydro guy so my opinion really isnt worth much tbh

this is her... she still has lots of green foliage but this is looking pretty weird.... im using technaflora's nutrient recipe... also as you can see some of the leaves are getting that blue tint... but the yellowing has been pretty fast too all this happened within 2-3 days...

what do you guys think?

dinafem has this blue widow picture with the blue leaves:

Looks great to me, nice work!!! She might be trying to turn colors for you.

thank you dude... shes my BABY! lol i also read that she can turn a little purple in colder temperatures so i have been lowering them a little...

Wow those are lookin good man!! from the breeders pic looks normal but idk i guess if the leaves are not drying up or browning i think your goin to be gravy lookin good bro!

It's a nitrogen deficiency. Common during the latter part of flowering too.

there might be a bit of deficiency there, but if it is a deficiency it's probably nitrogen and that is not necessarily a bad thing that late into flower. plenty of healthy green foliage left to carry it through until flowering is complete.

Next run try using your N rich fert or grow nute at a low dose right through flower to help reduce this.

should i add some of the veg nutrients to help a little bit? or is it not necessary?

im going to feed for 2 more weeks and then flush for the last week.

thanks for your input!

I feed small doses of N along with my bloom nutes up until week 6 of flower. Keeping them green helps with the end product.

no, i wouldn't try to up the N this late into flower, your plant is healthy enough to make it to harvest.

What i have found out is if you introduce Nitrogen at a much smaller rate and build up (early on say 2-3 weeks old) it is much easier to maintain throughout the rest of the life as you can add the desired amount.
For instance if you go heavy on the N too early, she will be super dark , most likely end up with chlorosis and you will find the leaves yellowing and dying in the flower phase way too early becuase you can't keep up that amount of Nitrogen.
Hope it makes sense this is my take anyway. Take a look at NPK ratio's along with micro's and learn how to balance them out.
Good luck brother.

Ok guys so this isn't just yellowing..... the leaves are also dying... is like she is drinking the juice until the leaves completely die!!!!!! im getting a little worried..... i mean she still got 21 days left and idk if shes going to have any big fan leaves by the end.... and she still has lots of white pistils and the calyxes are supposed to swell in the lest 2 weeks (in a week)..... ive also noticed that she has been drinking less.... kinda makes sense since shes practically eating her leaves... shes always had a big apetite her PPM has been about 1500 (3.0 E.C.) for a month now without a problem... fearing it was nute burn i lowered to 1000 PPM (2.0 E.C.) today...

the ph is always 5.5-6.0

the temp is usually from 70-80 in day and 60-70 at night... the humidity is about 35-40% the res temp has been a little cold lately but ive been trying my best to keep it up.. it is usually on 60-62 but it has gone down to 57-58 i read that below 55 is bad but it has never gotten that low.

im following Technaflora's recipe for success and like i said before this plant has been gorgeous and healthy all her life, ive never had a better plant... maybe im just sad that shes coming to the end of her life...

do you guys have any ideas?... im freaking out
