Uncontrollable Nitrogen Deficiency, Any Ideas?

Alright, I'm about 2 weeks into flowering (counting from when I saw the first budlettes) with my current plants, and I have a bit of a problem with one of them. I'm currently growing one female Chronic, one female White Widow, and one male White Widow (doing some breeding this time). The White Widow's have been very resilient and strong all the way through, no deficiencies at all, but the Chronic is a different story. This bitch has been a burden on me since she sprouted. At first in veg I had a nasty nitro deficiency, but I got that under control. Then it started "shedding" leaves. After it recovered from all the previous crap I just threw them all into flowering. Now her bottom leaves are dying off one-by-one, all are turning that piss-yellow color. It seems I have a nitro deficiency again, and I just can't seem to tackle it. I water with plain water every day, and once I week I use superthrive and some Bloom Booster MiracleGro nutes. Do you guys have any ideas how I can solve this? I fear that at one point all the fan leaves are gonna die off, which means the plant will bite the dust eventually as well.

Thanks.

Bloom Booster MiracleGro nutes

this is your problem....

this stuff is very acidic & it doesnt take much to burn and throw the PH way out of wack

complete a soil runoff PH test.......
with PH corrected water (6.5-6.8PH ) pour enough water in the pots so the water runs out the bottom of the pot ...test the PH of this water....

Im sure youll find your acidic & its caused nitrogen lockout

Thanks GG. Do you have any recommended nutrients to use while flowering? I was considering Advanced Nutrients, but that stuff is hella expensive.

yes it is

the manufacturers are smart, they pick great marketing product names, they choose seductive artwork or blooming photos
the important issue is the NPK values, ultimately the plant wants nutrients, nitrogen, potassium & phosphorus the 3 main nutes, and the plant doesnt care where it comes from, be it a chemical in a box or organic fish sludge.
the correct NPK values are the key not too strong that it burns but strong enough to push the plants to its potential and more importantly at the correct times in its cycles


FOR THE VEGATATIVE CYCLE
Miracle-Gro® Water Soluble All Purpose Plant Food (they make several fertilizers be sure its this one)
http://www.miraclegro.com/index.cfm/...c0236933b0a7a4
Fertilizer Analysis npk : 24-8-16 with micronutrients
2 level "Teaspoons" per gallon of water, (reduce this by 50% first time application) feed every other watering............use this as your water......... till flowering



FOR THE BLOOMING CYCLE
Fertilome, Root Stimulator and plant starter...
the NPK is perfect: 4-10-6
2 teaspoons per gallon of water every other watering........ use this as your water ...discontinue use 3 weeks prior to harvest...flush last 2 weeks...thats it no water .....


this is just like fishing lures, MJ DESIGNED FERTS are designed to catch your money not so much the fish
