Harvey's #3: Northern Lights (fem)[Nirvana]

[HarveyHarvester]

I am looking forward to your progress.
I can help with the nutrient aspect if you want to hit me up. I create nutrients from scratch to fit specific strain profiles. At least 75% savings (especially if you are using AN). I have my own A-B nutrient formula made for NL#5
I grew this strain from Nirvana Seeds. If yellowing appears, just do a foliar spray with 1 tsp Epsom salt per gallon of RO water. In 2 days plants will green right up. This will also contribute to any forming buds.

Thanks bro!
epsom salt eh? I would never have considered spraying anything on them during flower but i will do it as soon as i can get some epsom salt. I have been increasing the cal-mag dosage along with base nutes and seems to be greening up a little but it's not that dark, lush green i like to see (lower leaves are dark green)

Thanks again, will try the epsom salt,
*edit* should i try to avoid spraying the buds?

it may be too much light.
there is a 600W HPS in a space a little less that 4 sq. feet... that's 4 square feet, NOT 4 feet square.
It's at ~20" and won't go any higher.

Your Light distance is fine with 600w.
If upping your CalMag, you may want to hold off on Epsom salt (magnisium sulfate) , or use half tsp Epsom salt per gallon, 1 time only. Wait 3-4 days to see results.
Be careful upping CalMag too much. CalMag is a specific % of Calcium and Magnisium and could create some lockout. This shows first with leaves yellowing from toxicity. CalMag is great but there is no play.

on the 17th, after going from 60% to 70% strength and saw no signs of it getting greener i gave it 3ml./2 gal. cal-mag plus in addition to 5.6ml. sensi cal mag xtra.
realized after doing so it probably wasn't a good idea. only once and seemed to have no ill effects but won't do that again. epsom salt next time!

I will leave it alone until its time to start backing off the nutes, if its still yellowish, will do the salt.

 

[HarveyHarvester]

I have a bag of co2 I can put in there but as i understand, that won't help anything with day temps at 74-76F. Is that correct?
I just can't keep from thinking that much light may have something to do with it. That is more light than recommended by a significant margin.

*edit* speaking of too much light, i added two 17" floro's under the canopy a couple weeks ago. lol. Grow Bitch! haha...

The first impression is a mag deficiency (Epsom Salts). I know NL#5 has this issue. OG usually has more than enough Magnesium.
As opposed to foliar spraying, you can also mix 1 tsp of Epsom Salt per gallon and simply pour this straight into your pot (just once) to root feed.
You can spray buds although with buds I would do so just as lights go to the off cycle to prevent any burning. However, this early spraying on buds will not have any bad effect. Give it 2-3 days to see the effect.

I do believe you know what you are talking about but just can't seem to bring myself to spray anything on those buds. RH is a real problem in that space and hope to never have a mold issue.
It is time to start stepping down the nutrients now in week 6 I think and was wondering what I was gonna do about the light green look.
I will add it to the roots next feeding.

Many thanks!
*edit* if you notice, it only seems to affect the upper leaves which from what i have read says Iron, personally... i think it may just be too much light. leaves can only use so much light in a day without additional co2 which would be useless at these lower temps. -my thinking.
will see what the salt does.

Iron is a possibility. Although now you are getting into trace elements, Iron is one one of the few chemicals that will play nice with your calcium nitrate (part b of a 3 part). This is when following instructions with your specific nutrient reg imen is so important. It's all about perfect balance.
Calmag works very well although many growers use it when unnessacary. 90 % of the time, a little magnesium sulfate (ES) will do the trick. Make sure Epsom Salt is un scented ..
When too many supplements and additives get thrown in, balance get thrown off.
Looking forward to see your results.

i think the use of cal/mag is dependant on the water u use.. r/o or distilled u need cal/mag,, if using good tap water its in there..ive lived in a few different houses and always used tap water, the ppm and ph differ from house to house but all had all the cal/ mag needed for healthy plants.. friends who use r/o or distilled need to add it as they contain zero elements..

 

[HarveyHarvester]

For what it's worth, my tap water is ~7.0pH./039ppm., I let it sit in uncapped gallon jugs to allow the chlorine to dissipate and the few plants i have grown out have all shown mag deficiencies. I don't know what the calcium in cal-mag does and know very little about nutrients. I only learn what i need as problems arise. I just follow the directions on the bottles, varying the strength a bit depending, and try to keep supplements proportionate.

I agree that using CalMag can depend on the water. Using untested water from your tap is growing using pure guess-work nutrient wise.
Where I completely disagree is that you need CalMag whenever you use RO water.
If you start with RO water, all complete nutrient regimens contain more than enough Calcium and a very specific % of Calcium and Nitrogen. If yellowing is occurring, it is always a Mag deficiency before Calcium.
I believe it is completely strain dependent, (assuming you are starting with RO water).
CalMag is more for the Magnesium than the Calcium. Yes, it will work because CalMag is designed with this in mind. But you are paying allot for CalMag as part of your regular regimen when you could buy a cheap bag of Epsom salt to achieve the same result.
Hydro stores love CalMag because so many growers are convinced it is needed as part of every feeding regiments.
We will have to agree to disagree on this one.

Awesome tap water!
If you ever see any yellowing, yes, I'll say it again. Epsom Salt (unscented) 1 tsp per gallon foliar spray. Allow 2-3-day and I guarantee you will see awesome results.

Thanks man, feed is tonight and am working to get my partner-in-crime to bring me some. (transportation problem).
We will see how she looks friday (photo day).

I will also try using the salt instead of cal-mag as part of normal feeding on the new plant I have started. good tip!

Cheers!

ok guys, I added the epsom salt to her fert mix tonight.
according to the package, it's gonna make her shit.

 

[HarveyHarvester]

hey guys, go back and look at the very first photo. note the light cord in the back, left corner.
see all that white stuff on it? wrapped around it like a candy cane?
I wiped all that stuff off after that photo and now i see it beginning to form on it again in the same candy-cane way (recent photo).
what is that stuff and why is it wrapped like a candy cane?

Just curious, what package? The Epsom Salt? your nutrient package? What does it actually say?

 

[TheChemist77]

never used epsom salt,, never need cal/mag,, my plants are healthy using regular tap water and gh maxi series nutrients,, i average 1.5 gpw since i switched to ceramic lighting..

The epsom salt. it says:
USES
* For relief of occasional constipation (irregularity).
* This product generally produces bowel movement in 1/2 to 6 hours.

I was just jokin' around tho.

That is far better than i have been doing on a per watt basis.
I think space is limiting my yields.
