That makes for some expensive coffee! Holy sheeeeit that stuff is pricey.
Maybe- but even with premium organic coffee it's still miles cheaper than that burnt ass roast corn syrup laden starbucks crap... lol And the flavor actually really adds a depth to coffee and tea if you like a little hint of molasses...
Ok I'm ready to be back on topic now :)

thanks for the replies fellas. :)

irish what is a good indication of mag def.? ive been looking at the pics you just posted and the only thing i can notice from the pic are slight browning on the tips of the sun leaves but i know that could be from a variety of things.
i actually have a little test subject i guess you can say haha its only a week and a half from seedling. so its still a baby, basically its purpose is to help me get a feel for the negative symptoms of the plant. so i actually intend to give this lil one hell (i know its fucked) BUT like i said its so i can get a feel for the deficiencies and toxicities and how they appear.
anyways its good this whole mag situation was discovered before it turned into a bigger problem, im sending your ladies all the good vibes i can send haha they still lookin good bro i never said this to a guy but i like your bush...........shit i wish my girls bush looked this sexy hahah

Lookin real good man... Magnesium rocks- I just discovered it for myself too. Got this stuff called "nature's calm" magnesium powder- wow. It relaxed me and helped me sleep better among other good benefits. One thing I read about transpiration is that high temps usually require more K (potassium) to support the high transpiration that cools the plant in the heat and also helps it to draw in all the other nutes. It's not a real world experience, but worth looking into for you maybe... As I told ya- I'm going to have fairly high temps in my grows too, so it's good to see u kickin pretty good ass in those temps...
ya humans and plants have allot in common, just like we want more K in the heat and bananas are good for that.
ur right ive heard K is good to use and i try to add more of it when i can with certain additives. Earth Juice makes a good K additive called metal k or something?
That makes for some expensive coffee! Holy sheeeeit that stuff is pricey.
its really not that much, it gose a long way. i paid like $7.00 for a few pounds, very easy to mix and not a mess like molasses. expensive is all the molasses additives the hydro store sales.lol. its perfect enjoy good coffee and also let ur plants enjoy it also. kills two brids with one stone.lol

here my friend this will be some help for you. i will PM u some stuff thats a must to know.


Magnesium (Mg) - Micronutrient and Mobile Element


Magnesium helps supports healthy veins while keeping a healthy leaf production and its structure. Magnesium is significant for chlorophyll-production and enzyme break downs. Magnesium which must be present in relatively large quantities for the plant to survive, but yet not to much to where it will cause the plant to show a toxicity.


Magnesium is one of the easiest deficiencies to tell… the green veins along with the yellowness of the entire surrounding leave is a dead giveaway, but sometimes that’s not always the case here. In case you have one of those where it doesn’t show the green veins, sometimes leaf tips and edges may discolor and curl upward. The growing tips can turn lime green when the deficiency progresses to the top of the plant. The edges will feel like dry and crispy and usually affects the lower leaves in younger plants, then will affect the middle to upper half when it gets older, but It can also happen on older leaves as well. The deficiency will start at the tip then will take over the entire outer left and right sides of the leaves. The inner part will be yellow and or brownish in color, followed by leaves falling without withering. The tips can also twist and turn as well as curving upwards as if you curl your tongues.


Excessive levels of magnesium in your plants will exhibit a buildup of toxic salts that will kill the leaves and lock out other nutrients like Calcium (Ca). Mg can get locked out by having too much Calcium, Chlorine or ammonium in your soil/water.
One of the worst problems a person can have is a magnesium def caused by a ph lockout. By giving it more magnesium to cure the problem when you are thinking you are doing good, but actually you are doing more harm then good. When the plants can’t take in a nutrient because of the ph being off for that element, the plant will not absorb it but it will be in the soil… therefore causing a buildup. A buildup will be noticed by the outer parts of the plant becoming whitish and or a yellowish color. The tips and part way in on the inner leaves will die and feel like glass. Parts affected by Magnesium deficiency are: space between the veins (Interveinal) of older leaves; may begin around interior perimeter of leaf.




Problems with Magnesium being locked out by PH troubles

Light Acid Soils, soils with excessive potassium, calcium and or phosphorus


Soil

Magnesium gets locked out of soil growing at ph levels of 2.0-6.4
Magnesium is absorbed best in soil at a ph level of 6.5-9.1 . (Wouldn’t recommend having a ph of over 7.0 in soil) anything out of the ranges listed will contribute to a Magnesium deficiency.



Hydro and Soil less Mediums

Magnesium gets locked out of Hydro and Soil less Mediums at ph levels of 2.0-5.7
Magnesium is absorbed best in Hydro and Soil less Mediums at ph levels of 5.8-9.1
(Wouldn’t recommend having a ph over 6.5 in hydro and soil less mediums.) Best range for hydro and soil less mediums is 5.0 to 6.0. Anything out of the ranges listed will contribute to a Magnesium deficiency.



Solution to fixing a Magnesium deficiency
Any Chemical/Organic nutrients that have Magnesium in them will fix a Magnesium deficiency. (Only mixing at ½ strength when using chemical nutrients or it will cause nutrient burn!)
Other nutrients that have magnesium in them are: Epsom salts, which is fast absorption. Dolomite lime and or garden lime (same thing just called different) which is slow absorption. Sulfate of Potash, Magnesia which is medium absorption. Worm Castings, which is slow absorption. Crabshell which is slow absorption. Earth Juice Mircoblast, which is fast acting. (a must buy!! Has lots of 2ndary nutrients).
Now if you added to much chemical nutrients and or organics,( which is hard to burn your plants when using organics) You need to Flush the soil with plain water. You need to use 2 times as much water as the size of the pot, for example: If you have a 5 gallon pot and need to flush it, you need to use 10 gallons of water to rinse out the soil good enough to get rid of excessive nutrients.



Picture one shows a mid grade magnesium deficiency.



now if u look its looks just like my pics. latter stages of mag is browning

but heres a pic of my girl now and u can see how they look alike

yup their no doubt their flowering now! good stuff! now i have to adjust my flowering time and go by what week they look like so i can tell when and what stage they are in for i know when to do certain things. thinking about calling it 7 days today because that's where about it looks to me. no sense going by 6 weeks in flower and confusing myself on harvest and certain things.lol

no kidding.lol. guessing the 10/14 light has to do with it. i went in their today and was like cool their shooting a descent amount of hairs now. i wouldn't think in 24hrs they could get enough food to make a difference?

It's possible- I know in aero it can happen in only a few hours as there is no grow medium to buffer- but either way, can't way to see the next batch of pics you come out with now...

wanted to get ur guy's thoughts on this. going to swap out my 2x500's for something equal to watts but in smaller panels. just wanted to get some opinions. above my 4'x4' tray 4x290's? or 6x180's? whats your reason for the setup u think would be best? i was going to go with the 4x290's but wanted to here other thoughts on this?

I wish I could help, but I really don't have enough experience with lights in a growing application to give good advice. (I'm lucky enough to live in the tropics where the sun is 12/12 year round). Perhaps my only advice is to see which bulb configuration would provide a better spectrum... I am also still really unclear on if lumens are linearly additive or not- that seems to be a big debate among growers, but I'm sure it's a good question for my friend who is a physicist for nasa...

I don't see where it would make much of a difference. LED in not HID where the wattage difference comes from a single point source, and higher wattage does directly relate to light penetration depth. With LED all the diodes are the same wattage, and I don't see where adding more is going to change the light penetration depth. It's all a matter of coverage and light angles. I personally think that 500w of LED in the small footprint of the current housing is just too much. Now if they took those same 500w & put them in a panel that was 3' square then I think you'd have a winner. But if it were me I'd go for the 4 - 290's on a 4x4 space

I would predict that 6x180w would be the stronger setup and would dedicate a 180 per 2 square foot. You would also have the benefit of multiple overlapping light at different angles which should result in a more efficient method of achieving penetration. Light intensity can match the higher wattage panels based on being placed closer to the canopy so with out a doubt this would be the most efficient and productive setup.

Yes it is a matter of light angles thats why the over lapping of light from multiple panels would increase light intensity and would increase penetration from the canopy being hit by lighting from multiple angles. Think about it, with all the foliage on a plant you would benefit from all the overlapping angles to get in and around the foliage. Since LED lighting is so insanely directional this would be a far productive method for achieving penetration.

thanks guys. ive thought about both points. i get more watts with the 290's and should be more then enough for a 4x4 space.lol

but my thinking was that multiple 180's laying over the space like a blanket of leds would allow more intense foot print and penetration for them being closer.

but one thing to keep into mind the 180's are smaller 15"x8" and the 290's are 19"x13"

i think either way they will rock

Just for the sake of adding another option in the mix, have you thought about doing a 290 in the center surrounded by four or five 180s?

I think the 180's would be the best... I'm trying to imagine twice as much light as i have now, in the same size area..... it would just be insane!!!! I'm all for the 180's but in your situation with the heat, you might wanna go with the 290's.

oh bro ive thought about allot of things. yes i did though. i do want to keep it one model this grow and see how each light dose. shit why not 10 100w spectra ufos.lol

ive been wondering witch would be more heat? either way sooner or latter ill be doing both grows.lol

how are ur girls?

Sounds good, and it helps the LED growing community collect some data on using multiples of the same panels!

ya i made up my mind it will be the 290w panels this run and latter on down the road the 180's. mainly because thats what i wanted from the ge tgo and GLH already ordered those for me and i dont want to wait longer for the 180's. also in a 4x4 area i dont think its that much of a difference like it would be in a larger area.

so keep a eye out next week i should be rocking the 290's hoping all 4 if the summer heat stays down.lol
