First time soil, plants issues?

Ok so this is my first soil grow, I have done hydro with great success and enjoyed it but I wanted to try soil for a little more ease.
I am adjusting to soil world problems but this one seems to have me a little puzzled let me explain...

8x8 room walls have B&W poly on them.
2 600w MH bulbs however one is running at 50% for now.
6 inch intake of fresh air and 4 inch outake.
Average temp ranges from 75-78 day time and 66-68 night time with humidity at about 40% the whole time
Seeds started off in a miracle grow garden soil and did fine
They have been recently (2 weeks ago) transplanted into Sta-green flower and vegetable garden soil,
I added some vermiculite and perlite also some store bought compost (Harvest superpowered organic compost) Its prob 75% sat-green and 25% compost.
I am feeding them well water with 50-75% power General Hydroponics Floragrow nutrients
Strains:
Violator Kush-4
Sweet God- 3
Lemon head band Kush-1
Aroma-1
Royal Highness-1


Ok so about a week ago a couple started turning yellowish, then a couple went completely yellow from top to bottom. I thought and thought, figured maybe the soil was too low ph so I made up about 25 gallons of 50% nutrient water of exactly 6.5 ph and flushed the crap out of them. I tested the water running out of the bottom of the plants and turns out almost all of them was at about 6-6.2 telling me the ph was prob lower than that, and the bad yellow ones were really low 5.7-5.8. So i figured a nutrient lock out...
Its been 48 hours now, while they have had some improvement they still have me worried. Not sure what to do other than sit and wait.

I thought about doing some Foliar feeding of GH Floragrow only suggested dosage, or give a shot to each of just Floragrow no water at the base of the plant. Prob stupid but not sure what to do here.

Im just thinking its a nitrogen def.

Killing them with love #4. Too much nutes...... already nutes in soil. Just water is all they need. Not N deficiency, you have N toxicity. They are a bit hard to tell apart but according to your line up those plants are hot

Does make since....
Wondering if I should flush again or just let them chill.

Id water on the dry side....more flushing means more nutes are being released.

just found this

reread my 1st post

When you use coco designed to grow dope and hydro nutes you wont get these ph issues soils get. Your ph is too low and as you can see by the chart your uptake of N,P, and cal ,mag is inhibited.

Bought a ph soil meter today, its one without batteries. Not too sure how reliable they are but every plant showed in the 5's, its not too specific but looks like i need to adjust the ph, which was my original thought. Just not sure how long the turn around time is.

If youre going to do soil then drop the bottled nutes and do some research on organics and building your own recyclable soil. If you want to stick to the bottled stuff and the phing crap, just go back to coco. Right now your getting the worst of both worlds and could save yourself a lot of trouble, imo. Those soil pH meters dont do anything in my experience btw, if you chose read more about organics you will understand that a good soil regulates pH by itself.

just some random garden soil and vermiculite, pearlite, and a splash of compost? i agree with ya op. N def. id throw a three quarter dose of some veg nutes (synthetic) and wait three days. you'll know if they get green again. if they curl in two then flush on day three but id think they smarten up for ya.

Southerner, I agree about dropping the nutes. I have done my research and currently getting some stuff together for an outdoor grow but I don't have all the stuff yet.
I threw together what I thought would be pretty good stuff, used almost the exact same thing for a mother plant that is thriving. I agree with the coco, could save me a lot of trouble imo too. I failed to add some lime in all this mess so I'm thinking that has a bit to do with it too.

Alienwidow- Thats what I'm thinking do, prob gonna hit with a light (25% strength) foliar feed to help quicker while the dose going to the soil kicks in.

Ill update in a couple days, hopefully they bounce back. Im about ready to throw them into flower.

Ok well here is an update....
After they have been flushed and then added a tbsp of dolomite lime aprrox 1" under the dirt and then a day after hit with 50% strength grow nutes they have finally perked back up and greened up real nice. Ill try to throw up some pics but, just yesterday I received my new LED lights and you can't see the green because the red/ purple is too strong.
All is well not, even had a couple mushrooms pop up out of the bottom of a couple of my pots.

So Diabolical666- sorry you were just way off, nute toxicity makes the leaves dark dark green not light green/ yellow that happens because all of the nitrogen is all gone. You may want to study your deficiencies a little more. And it wasn't too much love either. It was a nutrient lockout due to low ph because i didn't give the soil long enough to settle into each other before transplant.

Do drain to waste hydro or organic soil. 50/50 is problems.
