Nice deep green. No tip burn. Leaves look good. I second Moflow's recommendation to go for 40,000 LUX in flower. *Just my opinion!

These girl looks healthy to me. Nice dark green, no burnings on leaf tips and margins, no signs of deficits, they all looked happy. Probably another 5 or 6 weeks till finish.
In the upper post there is a paragraph about bleaching! But there is not much to say. Best is google bleaching and look at the pictures ... It starts with yellowing on the upper leaves followed by slow drying and dying of the leaves.I suspect my lux meter also reads low. Are there any easy to see signs of to much light?
Velleman is a brand that sells OEM china stuff at triple the price you pay for the same items (albeit in a different color housing) directly from China though.I dont have cheap china lux meter , I have velleman lux meter DEM300 and it is a brand new so I want to bealive that the readings are correct
Slight miscalculation......Velleman is a brand that sells OEM china stuff at triple the price you pay for the same items (albeit in a different color housing) directly from China though.
You can estimate the light levels from the datasheet too. If you have 4 Citi 1212 at 50W, according to the specs they would be producing about 440umol/s. If your tent is 60x60 then that is way to much. That would result in about 1220umol/s/m2. Even if you take away 20% in wall losses then you'd still be at around 1000umol/s/m2 average, but much higher in the middle.
125W to 150W would probably be a better match for that size tent and those COBs. Then you can put the lights at 25cm above the plants (limiting wall losses).
I would use the Biotabs then as recommended. It should at least cover her minimum demands. But I would buy something extra for the next run.[QUOTE=" And I would also get a bloom fertilizer (¼-½ dosage) to provide sufficient nutrients in the main flower stage (now!). Atami has a good organic fertilizer series./QUOTE]
Dont have any thing other then biotabs starter kit so can I add some nutes from biotabs for main stage of flower-now ?
OMG...but on the his box say country production : belgiumVelleman is a brand that sells OEM china stuff at triple the price you pay for the same items (albeit in a different color housing) directly from China though.

Where is simulatio for 4 COBs Par ?Do not move them closer together, this only creates a center hotspot and you get less light on the sides. Look at the simulation for 4 COB's above, your PAR map should look similar, of course not with the same intensities.
I think that I heard that light bleaching have a thing with spectrum and heat of the lamp not lumensAt 22,000 lumens with my led's I get bleaching.
Yes it's good for 80x80, but you said you have 60x60 which is almost half the surface of 80x80.This is from the site of the store that I buy cobs...
So they say perfect for 80x80
And what about umols ?I really dont any thing about them ...just start reading
Just take a deep breath and relax, you're over thinking it. Lolsorry again for quality of the picture... fucking bad mobile phone
so I dont know if you can see but meter gives 25 k on the centar....
so lower down the light ,close cobs each other or dim it more then 200 w...now I run them at 200w
or set it as it is and hope it will be ok like this...
I really put all my money to this for cobs ,tent,biotabs,wall meter,lux meter,ventilation......
and really really want at least 50 g dry indica to help me sleep good...
so please any leatter from you guys means a gold to me
and really thank you all for help...
Just for curiosity could you place the lux meter about 8" ~ 200mm directly under a cob to see what reading you get? Nothing scientific, I was wondering how high your meter will go!
Or try lowering the light until you get a 40K reading in the centre, then take readings around the edges of plant.
55 000 - 60 000 10 cm under one cob...Just for curiosity could you place the lux meter about 8" ~ 200mm directly under a cob to see what reading you get? Nothing scientific, I was wondering how high your meter will go!
