pale plants

[dmtcorey]

Morning!

got a consern with my plants here ,
i have noticed that the my kush plants in the back row seem to be pale compaired to the ones that are more under the light ,i moved the plants around and put the pale ones more under the light where the healthy ones were.
its been about 2 weeks into flower and the healthy looking plants are throwing off some nice little berries that are larger and nicer then what the pale plants are throwing out,
just wondering if it is from maybe a lack of light intensity that is being expressed or maybe there is a problem with the plant not being able to up take nutrients.
all plants are the same cut,og kush ,and i have been running this cut for over a year now!

do you rotate all the plants 1/4 of a turn each day so the plants gets direct light alround them?
need info on room size wattage etc.a pic or few would help.possibly lack of strong enough light and cooler where the outer plants are.how regular do you change bulbs?

plants get rotated 180d about ever week! room is 9x11 with a peak like roof but im only using about 4x8 with 2x 600w hps,and this is the second run with the bulbs,and ill have to wait till tonight for pics ,lights dont come on till 5 pm and there should be even temp through out the room ,i got good fans and ventilation going,temps are avg 26 with lights on,and 15 when off!

peace

A tad bit vague...Please expound a bit on your problem...

What media are you growing in?
As far as plant fertilization, you are using...?
etc...

but im only using about 4x8 with 2x 600w hps

I've never used a 600 over a 4x4 area before (3x3's successfully) I'd be curious to hear how that actually works out in practice for others in the real world...compared to say a dual 1000 watt affair.
...hopefully we can dial in a solution here that will help you and also other future forum readers.

Thanks for the replies fellas

media is %45 mushroom compost %45 promix bf %10 perlite,and im using pure blend pro for nuts ,
so far im thinking of giving things a shot of seaweed extract and maybe some epsom salt to see what happens but iv used a 600w in the 4x4 with good results ,
acually i used a future bright 600w that my friend lent me side by side with a 1000w grow flux ballast with a brand new hortilux bulb and got better yeild and larger buds with the 600w with a used bulb,but i do think the 1000w was to close cuz there was some bleaching on the plants with probly reduced the yeild,but i have been vary pleased with the results of the 600w in the 4x4 space!

what do you feed them and at what strenght?do you adjust ph of the feed?do you test the run off ec and ph? your lighting is fine.what is the grow area lined with and do you clean the walls,shades etc between crops for maximun reflection ?
