Small orange spots on leaves???????

Sorry for the lack of photo evidence but will definately post a few pics in the next few days as this grow is goin really well -- ((borrowing my mates digi-cam later this week))
Everythin goin really well -- getting some amazingly bushy plants with some awesome secondary growth and already one shown itself to be female and only 4 weeks into veg.
Growing in dirt/perlite/verm mix -- 4 babies with 3 x 125 watt envirolight 6400k blue spec lights on 24/0 with 2 fans blowing 24/0 - not nuted at all so far just watered when dry -( just tap water but checked to be spot on ph everytime)
noticed today small bright orange spots appearing around quite a few of the leaves - mostly the lower/older growth but really wanna know what`s causing this.
i`ve not had a single hitch on this grow so far and they`ve been so healthy so i`d hate things to fuck up now because i failed to overlook something.
Anyone know what`s causing this??
Some nute deficieny????and if so what??????

Sounds like a Mg deficiency to me. Add 2 teaspoons of epsom salt per gallon of water and they should be getting better in 4 or 6 days. Keep adding the salt per watering until the deficiency is gone.

Or so a growing book tells me. :)

Cheers 4 ur reply sticky
I`ve seen and read quite a bit on here lately about deficiencies and nutes etc but it all seems a bit overwhelming really!! :confused:
One site i looked at recently suggests its a calcium deficiency and not mg but hard to tell !! ( www.canna.nl)
so many different typa nutes on the market all claiming to be the best!!
Like Miracle grow for example and everyone screaming on here not to use that cos it`s shit!!
And if you over-do it with the nutes you do more harm than good so yer -- definately an area i could use help with!!!
What to use and when????? :confused: :confused: :confused:
