Question About Nitrogen

[Guest]

I'm running some Strawberry Haze right now and noticed one of my plants is showing signs of nitrogen deficiency on a couple of fan leaves. I'm at day 36 of 12/12 and cut off the nitrogen after they second week of flower by switching from FF Tiger Bloom (which has a bit of nitrogen) to EJ Bloom which has none. Considering I want to keep these in flower another 4-6 weeks am I better off adding a little nitrogen or should I forget about it and not add any at all. Thanks for your input in advance. Here is a picture of part of my grow. They are just starting to fill out nicely.

If you have 6 weeks left and they are already N defficient, it would be good to give them a drink. I would give them another watering of a vegging fert.

Thanks JJ. I read a few threads on this and there is differing schools of thought. My thought is that in nature, nutrients are readily available and a plant is going to take what it needs. More nitrogen it is, then.

just supplement with a little nitrogen not a huge dose.

Just wanted to agree with scorpio nitrogen doesnt delay flowering like its so commonly said,it enhances veg growth and health which is a totally different thing.It is true that nitrogen is the biggest culprit of the ferts when it comes to "nasty taste",but you'd literally have to use a bit of it shortly before harvest before it would have any effect.I'm talking soil of course.Yea green those fans up if you can they'll only function better.

 

[jojajico]

i think that a lack of nitrogen helps to signal greater flower production though. to spend less energy on green foliage growth and more on flowering.

 

[Guest]

I agree towards the middle or so until the end,but those first three weeks are when the most furious vegetative growth takes place and nitrogen can be doubled in some cases from what you may have been using in veg I've found.I want to keep the fans viable all the way through if possible,hardly works that way in reality though lol.

 

[jojajico]

agreed.

Ive had a give a little N boost in the early stages of flower before, to plants that just ate huge amounts once flipped- I wouldnt supplement with any N much after 4 weeks (depending on strain) but for you adding a little N will do more good than doing nothing IMO.

Like Ballastman, never noticed any delays in flowering production when I've needed to add some N. Lack of N can really reduce your final yield, I think alot of ppl overlook it too much-just consentrating on p and k in flower.

jojajico we always seem to agree though we always express ourselves differently,the outcome is always the same lol we normally agree totally.Maybe we should just merge our concsiousness to forgo all this confusion and dual-posting,it can be done with enough blockhead lol

 

[Guest]

Thank you everyone so much for your input. Only one of the four plants showed a nitrogren deficiency on just a couple fan leaves. With a long flowering plant only 4-5 weeks into flower it seems like a little nitrogen will do the trick.

lol genius thinks alike lol. though i think u have far mor experience than i do, im simply a researcher i spend hours on whatever im interested in.

I have a strain I grow that's VERY Nitrogen dependant... a week/10 days w/ out some N and it'll YELLOW in days... EXTREMELY YELLOW... I've learned to give it some N up untill the last 10 days or so...w/OUT it I end up with buds and NO leaves w/a MONTH to go!!! COOL strain tho... ZERO stretch.. maybe 2" TOPS...but bushes great and HAS TO BE DOUBLE BAG'D once finished...

ME thinks you two ALREADY HAVE a room...

In flowering too now, and the top fan leaves and budsites look like they are not getting that much nitrogen but all the growth on the bottom is lush green? any suggestions? Also put an extra dose of nitrogen before its too late?

The foliar spray helped a little yesterday night

peace

I just read this in a sativa thread.. Not sure if its accurate or not.


now very few people realize this but how long sativas take to harvest is very closely linked to fertilizer regimen. during the end of mid flower leaves begin to yellow but the buds have more time to them. growers react the same way they do with hyrbids and touch it up with a tea heavy in N. when really the plant was getting ready to finish and its part of the sativas biological clock was kicking in; the grower inadvertently told his plant that death was not coming, to keep striving to live, and the plant takes much longer to finsih. let me get an exerpt from mj growers handbook to help me illustrate how and why this happens.

 

[Guest]

You can say the same about many indica's staring to yellow around mid-flower,but adding nitrogen isnt going to actually delay flowering if thats what he's getting at.It wont take the plant longer to finish if a little nitrogen is added midflower,I know you probably read that in a reputable book but thats not my experience at all.I've grown a few 85 day sativa's too and nitrogen intake during any part of flowering isnt going to affect finishing time,not to the extent you would notice anything.The only danger giving a plant nitrogen later in flowering is that N is the biggest culprit when it comes to the "nasty" taste erb can have if it contains too much nitrogen in it.N doesnt6 delay flowering,it enhances vegetative growth which in turn leads to healthier flowers in the long run.Thats why I'll never understand people saying they like to see their fans yellow around midflower,it'll never be a good sign in my eyes.Normal to a certain extent yes,but a positive thing?I dont think so.The most beautiful finished flowers you'll ever see will be on a plant with green vibrant fans until the end,not gorgeous buds with yellow dying fans.Thats what I've seen anyway

i usually hit it with one good nitrogyn feeding at the end of veg and indo bat guano, molasses, liquid kelp thru veg. I found that interesting because i have a sativa in week 9 and have no idea when it will be done. my leaves has yellowed and i took it as a good sign.

 

[Guest]

Yellowing leaves can mean a ton of other things besides a sign of maturation thats for sure,is it a bagseed sativa with no history?I'd be scared myself to even attempt that lol.Every time someone tells a newbie to start with bagseed I'm like WHAT are you trying to do to that poor kid?Bagseed has no history,usually is sativaish,and can take 120 friggin days thats if it ever feels like finishing lol.If you order an inexpensive strain from a seedbank on the other hand,besides having a written history of finishing times,yield that sort of thing,you can always get info on the strains from people growing it on the forums.Man blockheads got me ramblin.I lost my dad 3 days ago,here I sit when I should be thinking at aleast about the eulogy.I'm gonna miss that cool guy I mean it.Anyway WTF was I ramblin about lol,yea sativa's can be cool or a real pain in the tucas.If I flower a sat for 85-90 days and it doesnt look near finished,into the trash she would go fuck it

Sorry about your father.. I lost my wife last april and still recovering.. Yeah its from bag seed, but exceptional bag seed. I only got one seed of 20 to sprout and it became a deformed seedling.. It was also female and i grew it along with my NL and it turned into this






Its alot different from my NL which i harvested already. It has less trichs and they look different then on an indica.. I am tempted to cut off a bud.. i watch it closely every day. This is week 9.
