FInal 4 weeks, leaves turning yellow. need help pics included

This is my first time growing..
So far I made 2 threads about my spidermite problem.
I have been spraying them down every 3 days with the lights off very thoroughly.

It seems like my spidermite problem is getting under control because every time I put them under the miscorscope they get harder to find, compared to before I would see one run by every 3 seconds...


My setup:
A grow tent with 4 lights(1k watts each) 2 fans, CO2 system, with a heater, humidifier and dehumidifier.
For soil, I mixed an old super soil recipe.
The environment is prefect(avg 74 degrees, 45% humidity)
And I always check to make sure water has perfect PH levels
Since I dont want to overfeed since I am already using supersoil, the only chemical in my reservoir is Bloombastic.

My problem is, today when I came in to water, I noticed more leaves turning yellow....I dont get what the problem is.
My theories:
1)Spidermites-I am trying to contain them as much as I can, using pest strips, and spraying them down with mighty wash every 3 days.

2)Over watering-what are the signs of overwatering...? I only water them once every 2 days because the soil is always moist when I check, plus I have rocks on top of the pots so the water distributes slower.

3)Not watering enough-again what are the signs if they are not getting enough water?...like I said I only water them once every 2 days because soil is moist but should I water them more?

4)Too much Bloombastic-How much am I supposed to use? On the back of the bottle is says you can use 2-4ML per gallon so I use 4ML per gallon is this too much?

Please help and look at pics and tell me what you think

It's either Magnesium, Nitrogen or Sulfur. My bet is on Nitrogen, did you feed veg nutes for the first week or 2? I grow in Coco myself but I think with soil you're suppose to have a wet/dry period, something like top inch dry then water. Under watering for me I find the plants new stems become soft, bending over. I'd start with just 1.5ml and work my way up

In this case when leafs are becoming yellow, there is need of
good quality pest spray. With proper use of such spray the
leafs grow well and started to become green with the
passage of time.

spidermites suck, keep doing what your doing. Dry up your plants a bit. they shouldn't be soggy at all. It looks like your using 1 1/2, 2 gallon pots, water them twice a week (Sunday, Wednesday for example) after they've dried up a bit. Bottom water them, let them "suck" the water up...
many times people use to much bloom fertz and not enough Nitrogen, your leaves are dark green( tells me the N is good) but give them a shot of grow fertz( although they are budding they still need N) (If you made your soil, I suspect the N is about gone)
I use Jacks classic 30-10-10 for grow, 20-20-20 for bloom- with a touch of 10-30-10 now and then with a touch of 30-10-10 as needed.
The barbs on the leaves are plentiful, looks like theres 12 barbs or so per leaf but they are rounded, you want them sharp and pointed.
do one thing at a time and observe, the plant will tell you what it wants once you get in tune with them.

BTW, many plants leaves will turn yellow during the last part of the bud cycle.

This thread is dead, don't know why it was brought back from the grave.....

2/28/2013 is dead??.....OK...

Its called fall. the light cycle change is fall and in fall leaves change. Dope isint a pine. it has leaves. unless said leaves are dry and curling up, or spotted, or nasty viens, theres probably no issue. the leaves will even feel leathery
