several problems with first grow blue mystic 5 weeks into flowering

[JuliusGreenthumb]

Hello guys,

I hope to find an answer here. My first grow ever - blue mystic strain from royal queen seeds - went quite well so far. but now (flowering week 5) for some reason the lower leaves start turning yellow, green leaves begin hanging down as well as some stems went red. last but not least even leaves have some red spots!

btw-One of the plants roots were damaged when i was putting it in another pot. Both were over-watered right after being forced into flowering...

I'm using a 600w hps-lamp

Here are some pics for you folks:


Here is one of those red leaves




Here u can see the yellow lower leaves
(small leaves from seed fell of some time ago)




This one shows one of those red stems




Top bud and even here the edges are red and the very tip is slightly yellow/brown








Thanks for ur help in advance!

your plant is fine ,make sure just flowering nutes used ,and it will finish triple that size with your 600.

She doesn't look bad to me at all. You want to see a Jacked up Blue Mystic?



This uppity little princess needs her PPM levels at 500, any higher and she burns up as you can see. Now, I have to state that your plant and mine come from different breeders and might have very different genetics. These Nirvana genetics are notoriously iffy and dialing in this plant compared to the other plants in the grow room is much more work than it is worth. Hell, this plant is like 40 days into flowering and won't yield more than 2 ounces... if that... I'll never grow Blue Mystic, or Nirvana genetics in general, ever again.

What I see on your plant is possibly just the slightest bit of Phosphate deficiency. Given the time of the plants life, a very slight increase in Phosphorus could make a big difference. Keep your eye on the Potassium levels and really start to back off on the Calcium. Other than that I think she looks just fine. Doing well for what I consider to be some interesting genes.

I'm talking about some seriously minor tweeks, just another 50ppms or so in the bloom nutrient department could make all the difference.

Then again, you can see what running just a little too much food can do to these plants. Ball is in your court, but don't do anything drastic.

thx for the advice .

i feed the plants with blooming-complex and a phosphorus - potassium mix from Hesi .

2ml blooming and 1ml phosphorus-potassium mix with 500ml of water every 2 or 3 days for each plant.

the pots are 33 liter (~9gallons)

is it enough , or should i feed them more nutrient or more sequently ?

my first idea was that i overfertilizated the plants, but you say it could be a deficiency of phosphorus... what makes you think of a deficiency ?! i'm a little unsuspecting about this issue...
another problem is, i'm using a phosphorus - potassium mix and you said, that i should keep an eye on the potassium (to much?)

another question is: what caused the shady red spots on the leaves ?

PPM? What does that stand for MicroMoles?

PPM? What does that stand for MicroMoles?

Nope, stands for Parts Per Million. Kind of like "out of a million", I think someone once used the term micro percentage.

 

[chazbolin]

so your reference was to part per million in lighting? 500 micro moles possibly?

 

[Snow Crash]

No.

Dude... Google can be really useful. You don't have to wait around for someone to answer your question if you take it upon yourself to find the information yourself.

Parts Per Million with regards to growing will always be referring to the concentration of dissolved solids (element salts) in water. It represents the number of non-water molecules present in the solution.

I haven't heard anyone talk about mols in growing. The nutrient companies do a by weight formulation to tell the grower the percentage of each element in the nutrient bottle. These calculations take out the need to consider multiplying the atomic weight of the elements by 6.023x10^23. They are displayed as NPK (Nitrogen, Phosphorus, Potassium) and listed as numerical values like 6-4-4.

Mols and light have no correlation. The real thing to consider is Photosynthetic Photon Flux Density (PPFD). This describes the amount of energy the plant can directly access. Lumens is not an accurate representation of lighting and CRI ratings have no impact on the effectiveness of a bulb.

 

[chazbolin]

Dude; well said!

I asked because plant light is measured in packets of micromoles relative to a plants PPF and YPF needs. Photosynthetic photon flux with maximum full equatorial sunlight (2000 mm) saturation of this species @ 1500 -1800 mm and active indoor reception levels of 500+ mm (a value attained through proper lighting and measured by a quantum meter) is what I thought in your original response you had been referring to. I'll now know it as a ratio of the concentration of dissolved solids within nutrients.

Thank you for the complete explanation. It was much better then Googles.

No.

I did some research into micromols and lighting and learned a few things myself.
Good ol' Max Plank. Gotta love the people who changed the world, for the better...

With regard to lighting the only time a person would need to use MicroMols to determine Microwatts or joules of energy at a specific wavelength would be if they were designing the bulb themselves, or if they were building their own LED fixture (which some do), or if they really liked laser beams, Pchoo Pchoo. The calculations provide representative data for the builder to design the most efficient fixture or lamp. Fortunately most people purchase their lighting from commercial manufacturers who employ smartypants scientists who have already done these calculations and have translated the results to values that demonstrate their effectiveness or graphs that show the distribution of energy on a spectral chart.

 

[chazbolin]

So true. The Planck's Constant. An icon the world has never given enough credit to. Speaking of efficiencies; have you seen or tried the EFDL induction lights which rely on Tesla electromagnetic principles? You may find this site interesting http://inda-gro.com/gallery/album/9

enjoy your weekend

 

[chazbolin]

Ahh the Planck's Constant! Have you seen Tesla's EFDL principles being used for these these lumen efficiencies? There's some charts you may find of interest http://inda-gro.com/gallery/album/9

I agree with what you've said that growers rely on lamp construction and providing the quality (PAR) and quantity PPF/YPF but what I took away from this site is just how much of an influence visible light Kelvin seems to be in equating proper light wavelengths with our plants ideal spectral needs.

I'd be interested in your thoughts on these charts

Enjoy your weekend Dude

you gained your exp thru grow guides, didnt you? best to advise people if youve had hands on experience,

 

[Snow Crash]

What?
Oh is this part of the personal attacks you promised on me?

Good try dude. I've even posted a picture in this very thread with a problem Blue Mystic of mine. How could you even think I don't have hands on experience? Oh yes, it's because you're a child spreading misinformation.

Buds hasn't ever grown. He's 17 years old and lives with his parents. It's a sad life this kid leads guys, let's take it easy on him, he just wants the attention after all.

That exactly like my blue mystic from nirvana,i'm in week six and the plant looks like shite,i won't grow it again.

[malcolmxtacy]

you dont' use avagadros number to find mols you idiot, you use molecular masses found on the periodic table, and is different for each element, if you are trying to find mols of a compound you add up the molecular masses for each atom in the compound and divide the number of grams by it. using avagadros number will till you how many molecules are in your given sample. wheres your high school chem man?
