Northern lights,white widow.How much longer?!

Hey,
So i got 1 northern lights and 1 white widow in flower.
They're almost 4 months old.1 month seedling,1 months veg and about 6 weeks 12/12.

My equipment:
-Fox farms oceans forest and perlite soil mix.
-fox farms line of nutes.
-overdrive premium flowering nutrient.
-400hpw/mh
-mylar
-awesome temp control.(one of those big units)
-they are in a 3gallon grow bags.Wich is way too small for them,i know.
It's too late to transplant.

I was an asshole and only topped the one once.Didnt do much pruning,if any.(only taking off a dead leaf once in awhile)
Well,they got tall as fuck as you can see.
I'm doing some last resort bending on the white widow(on the right) and she seems to be responding pretty well.
So please don't diss me about it like before.
AND learn from my mistake,folks!!!!

I know the light looks far away but they would burn if it was closer.Ive got the plants surrounded with 4 foot fluors.

I am currently feeding them fox farms tiger bloom,big bloom and overdrive.
When should i start flushing them?
And how much longer till harvest?!
I am going for the couch lock stone.

After 4 months of slaving,is 3 OZ dry asking for too much?

Edit:They look very sativa to me.Did Nirvana screw me over on the seeds?

Anyone have an estimate?

those look VERY sativa to me as well.. 4 weeks?

4 to 5 weeks my friend

Ah,so they are gonna fatten up real nice.
So,when you guys said a grow could take 5 months.you guys really ment that.

Are they looking okay?
The tops of the plants look like a bit of heatstress.
Should i add a fan for the top parts of the plants?

3 gallon bag are plenty as long as they are getting their nutes, and I would some kinda fan in there, try to keep it as cool as possible. You prob gunna end having to supporting those buds with string and whatnot.......3 oz is a good safe estimate. Looks good and sativa pheno

At least another month, maybe little longer.

They definitely look REALLY Sativa like to me too. NL and WW are fairly stable consistant strains, getting really different phenos is weird. Of course I am not too familar Nirvana, maybe they versions of these strains are a bit different than the original, maybe not as consistant?

It must alot of sativa in those plants. Pure NL grows totally different.

Would now be a good time to introduce mollasses?
1.5 tablespoons of blackstrap unsulphered mollasses.water every other watering.
From now,till flush,till harvest.
Right?

Ill start flushing in 2 weeks.
In the mean time, i will drop by radioshack and get one of those portable microscopes.
60* should be fine,right?

Think i will run into any other problems?

Ever since the grow started,i haven't stopped stressing over my babies,lol.
