This is my first ever grow and so advice from any more experienced growers would definately be appreciated.
Basicly my problem is the sudden yellowing of leaves on the plants (I understand that this is completely normal in the lower leaves) that has developed over the last week or two. I didnt think much of it when the lower fan leaves started going pale green and then yellow as i knew this was normal but as time has gone by it has slowly progressed to the higher fan leaves with some of them now completely pale yellow and some of them falling off. Not only that but it has now started to spread to the bud sites (turning pale green) and i am beginning to worry about it. I was wondering if anyone had any ideas as to why this occuring. Please see the technical stuff below for a better idea of where i am going wrong.
-Big Bud XXL 5 weeks into flowering
-I am using/used 400w MH for growth and then 400w HPS for flowering (the usual 18/6 veg and 12/12 flowering)
-Nutrients: Plagron Growth, Plagron Bloom and Plagron Green Sensations (Not all at once obviously)
-Soil: Fertilised Subtrate Lightmix
-Temperature: Within optimal range (most of the time)
-Ventilation: Fresh air blowing in from the window with the side panels on the tent removed (top of tent door unzipped also). I am fullly aware this is nowhere near the best but i have to work with minimal space and maximum discretion.
-Water: Bottles left open for a minimum of 3 days and then shaken before watering. I use the rule of thumb method i.e. i put my finger in the soil about an inch to decide when to water.
-Other: I occasionally use dry ice to get some extra carbon in there but i also understand that to get the best results from this it has to be consistantly kept to a certain ppm (cant remember exact ppm)
I have attatched a few pictures to give you a better idea of the problem (sorry about the picture quality, I took them on my phone as fishing through my house at 4am to find a digital camera isnt very discreet given my situation)
