Man I need help so bad Im about to cry! There all dieing

I had another post but nothing ever was figured out on why? I have 6 white widows! Like 2 or 3 weeks ago I watered them and I started to see Nute burn. Well I flushed them and was good for a few days but then the leaves started turning yellow on like 2 of the plants! After a few posts here I We thought we had it with a over watering! Well thats not the case as there under a good fan and been moving the soil around some. and seems to just be moist. Well 1 plant died now 1 is on its way out and the other 4 are starting to turn yellow a bit!! I have some pic's the 1st set will be from the org problem and the 2nd set will be just about a dead plant!

Here is the 2nd set of pic's
Sorry forgot to add:

My ph is around 6.2- 6.5
soil is Bio bizz all mix
under a 600 watt light but only running at 450
temps are allways 75 threw 79

Yes sir thats right!

Your PH is kind of low for soil (I like mine 6.7 or higher) and "2 Tbsp of Molasses per gallon" is only acidifying the soil even more.

No more molasses!

The droop could be over watering, so keep an eye on that.

Once the soil drys out and the container feels lite, flush with 5 gals of limed water (1 tsp per gallon hydrated lime/or garden lime), and then top it off with 1/2 strength bloom nutes (no reason to starve it). Let her dry out well between watering's/flushing's

The leaves are going to fall, but that's normal, and the plant will look close to death by the time it finishes flowering, so don't get too freaked out about the normal flowering process/death.

PM me in a week or 2 if you want more help

Here are a few of whats happening now what the few left look like!

5 gl a plant? or all my plants with 5 gallons? sorry can't afford any mistakes at this point!

bro how many weeks in are they???? they look like they are finishing and the plant is just dieing off to finish naturally. (the bud stacked on there looks good). thats probably your problem. have you flushed? keep your ph 6.2-6.8. dont overwater at the end of a cycle.

Yeah you gotta flush some of that molasses out. Make sure the containers are very dry before you flush, and you won't have to worry about them being over-watered.

2 TBLS of molasses per gallon is way too much.

They went in to flowering aug 19 so they still have some time left! I will flush the lst 2 weeks if they make it!! What will the Lime flush do? And where can I get this stuff?
