Adding extra nitrogren during flowering?

Hey guys. First let me start by saying this isn't vital help, my plants aren't dying. I'm just curious about the below..


I'm 4 days into flowering some Tangerine Dreams (70 day flower) and I've ONLY added my GROW (as apposed to bloom) nutrient once.

I feel like my plants are a light green, I feel like they could benefit from some nitrogen, as I feel like I underfed them in veg.

I hear that when a plant needs nitrogen, it needs nitrogen, regardless of photoperiod..




I'm using Technafloras line of nutrients, Grow, Boost, and Bloom.. (pretty sure)

Could I just add Boost, and Bloom and a little bit of GROW to add some nitrogen, or would I want to go another route?

Day 1 flower, under a 250w MH (added MH pic so you can see the coloring a few days ago)

Day 3 flower, under 250w HPS

Outline: What do you guys think about adding extra nitrogen during the beginning of flowering? How would you/do you do it?



Thanks ;)

well it is good to use the veg nutes the first 2 weeks of flower cuz they use alot of N in the stretch. when i switch to flower i slowly decrease veg nutes and increase the bloom every feed untill i am no longer using a veg nute usally at the end of the 2nd week. then it is just bloom food and every once in a while it is good to through some more veg nuts in to keep them green and lush. using N is ok in flower just not using it in huge amounts, cuz it will delay flower time.
your plants dont look to bad at all though. i would continue with some veg nutes and slowly add more bloom till veg nutes are cut out

Cool man that's perfect! I was at first just going to flip to straight bloom nutrients, but great info on N being used during stretch.


While were at it I've had this question on my mind.. I'm in soil. Technaflora recommends doing ....Feed-Water-Water....

I used to use Advanced Nutrients and that was..... Feed-Water....

I don't see how they would be any different, they are the same types of nutrients?

I'm a newbie to nutrients though! Only my second grow. Nutrients is something that you just have to learn first hand, i'm figuring out!






Basically, I would LIKE to add nutes[mainly nitrogen] next watering. I just watered with plain water last time, so according to technaflora I should use plain water once more, THEN use my nutrient solution.

I plan on using half strength next, if that makes any difference.

What do you think I should do?
 
A.N. has a lot of salts in it, so be careful. Always water in between feedings is good & if your going to mix nutrients Never go full strength.
 
i always fed water, feed, water feed, water feed and so on and on. this way if theri is any left overs form the last fed the fresh plain water will help use them up and help not create a salt buildup of any sort.

i would do feed water feed water like said above.
i would give thema feed next if you just gave water last time. and use the same amount of nutes as you did in veg with the veg nutes.

I'm not using A.N., I'm using Technaflora... 'B.C Grow, B.C Boost etc.'

good call though on the never go full strength when mixing

Yes, I dig the importance of letting the plant uptake the dissolved salts.. what I do not understand is why my nutrient manufacturer [technaflora] tells me to FEED - water - water - FEED


Like I'm not usually one to go against the label, but I don't understand why I wouldn't just do feed-water-feed-water.

What nutes are you running mcpurple?
 
i am past my 3rd week in flowering & am still adding N...although this plant "sativa" wont finish till about may 1st. it was too sensitive during veg, & showed minor burn, so I backed way off & I know they didnt get enough, because bottom leaves have been yellowing & even falling off; much too early for this! I use both veg fert & bloom fert, along w/epsom salts. U just got to go by what that individual plant or grow needs & when. Ideally it works one way all the time, in reality it just aint so, lol. I also pretty much feed, water, water. And the reason is, it could take 5-7 days for the signs of ur ferts to show in the plant, & if you r feed water feed....u r not giving enough time in between to "evaluate" ur grow at that point & how the ferts r affecting it...yet u have already fed again.
 
I add extra N in the 3rd week of flower, after the plant has nearly finished it's 12/12 stretch.... I don't get a lot of yellow leaf in flower because of that I think. I do have to be careful and watch closely for Calcium and magnesium issues, they always sneak up on me...
 
For flowering in soil, I taper off the Grow formula during the first few weeks of 12/12, while slowly increasing the Bloom formula. I use the BMO Grow It Green (5-2-5) and Flower Power (1-8-7) as my base nutes. Anytime I see the lower fan leaves starting to lighten up, I mix in 5 ml of Cal-Mag (2-0-0), and it seems to green them right back up. Then nothing but water the last 10 days, and it's all good. Cal-Mag is my weapon of choice, for dailing it back into the green zone during flowering. For coco, I prefer the Canna nutes, for my base nutes, because they have less K.

Ok I see where your coming from. The nutrients are in rather high values too. I think I will feed the next time with nutes, as they haven't had much. Then once I get into the full strength I will start spacing out my waterings as recommended to better gauge the uptake.. I am currently only watering once every 4-5 days or so. I transplanted from 20oz party cups to 3.5 gals and vegged for 3 weeks before flower. So they are no doubt getting thirstier by the day.

Thanks ;)

This is what I was planning on doing essentially.

I have totally noticed how the leaves darken with MagiCal! I have been using it half strength, but the last time I fed I did full strength MagiCal (cal + mag) & full strenghh thrive alive.. 2.5mL/Gal




Thanks everyone, I have a feeling my plants are going to love this

I don't want to speak too soon but it seems like I've got the stretch under control... They haven't grown up into any hot spots suddenly or anything, I check the lights every day.. like a half inch of vertical growth a day pretty much

CalMag has several nutrients in it, including nitrogen.... as an added bonus, it is difficult to burn plants with Calmag.

Yeah I was reading that on the bottle ;) , I just wanted people to know the 'MagiCal' was basically CalMag :) thats why I pointed out the main ingredients.

But yeah I dig the CalMag... I'm doing 2.5mL per Gallon of water, in soil... thats the most Technaflora recommends using... how much do you think you could increase the strength of that? Or would you even?
 
I grow hydro and go by total ppm, so I really can't answer the question with confidence in my answer so I won't. :)

Yes, you need N while flowering. It's not bloom foods that produce bud (contrary to popular belief and vendor hype), it's foliage. If your foods induce premature leaf drop and yellowing, you're gonna lose production. Simple botany. Another thing, you keep dropping label names. Without knowing and understanding what's in your products, you're sunk.

Also, I can't see where 2.5 ml/gallon of ANY of the oil company products will have any affect one way or the other. If you study the GA, you're only getting 2.5% N. Any greening up is probably due to the relatively high Mg and Fe. Without sufficient N, at any time, you're gonna see some stunting and foliage issues. http://www.technaflora.com/products.php?product=19

This is what your leaves should look like. This one is 42 days into flowering.

Hey uncle ben!

I was actually reading in some of your older threads that spoke about adding additionalN for flowering. This is actually what got the wheels turning.


As far as label names, I totally know where your coming from. Plants don't notice a difference in label, nitrogen is nitrogen to them. I'm just using what I know out of memory, I'm not super well experienced with nutrients, so rather than possibly leaving out some information I chose to refer to them as they are called on the label ;)

The leaves aren't yellowing yet, they are just a light green that I feel could be darker... and healthier ;)



Thanks for dropping the knowledge, that cola looks perfect. You can tell those leaves are chop full of nitrogen, nice dark dark hemp green - that's what I came here looking for 8)

That's what I try to do, get the wheels turning, make you think and understand plant processes. Then you're empowered to make your own decisions based on common sense. The issue is chlorophyll - keep 'em green. Sounds like you're on the right track. The plant nursery industry standard for foliage production is a 3-1-2. For blooming, 1-3-2.

One of the problems I have with the oil companies is the deception. There are too many "Grow" foods that I wouldn't being to "grow" in that they are deficient in N and many times way out line on the K.

Thanks, I post that photo to combat the too much N mantra - "too much N will interrupt or shut down flowering!" Well, if those dark green ladies aren't flowering profusely, then my rice is cooked!

Good luck,
