HYDRO HELP! How will this affect my plants and yield?

[akron322]

I'm about 12 weeks into turning my lights for flowering cycle, and I've been getting these yellow color in the leaves at the top of my plants but not sure what the issue is...

I'm using a droplet test for pH to mainting the correct levels. I have also lightened up the nutrients to prevent nutrient burn.

The flowering stage is taking much longer than I anticipated.

Can someone please tell me whats wrong with my plants and why the flowering may be takig much longer than expexted?

thank you!

Just an FYI, I'm growing 3 plants of Northern Lights, using 6 CFLs

Hi Akron, what size pot are you in? What nutrients have you been and amounts lately?

 

[akron322]

I'm growing in a 10gal tote. I've been using general hydroponics and doing 1/4 tsp gro, 1/2 tsp micro and 1/2-3/4 bloom and change water once a week

 

[Mr.furley]

Sorry Akron I missed the Hydro title, that's my bad, Im not a Dwc not sure I'd be the best help and would hate to give you the wrong information.
I will tell you a grow is more likely to going a couple weeks longer then the breeders say, do you have a Jeweler's loupe?

It kinda looks like your plant is re-vegging. Is it getting 12 hours of total darkness? Spots are probably a calcium deficiency.

One thing that would help is adding 4or5 more cfls. And keep your lights no further than 2 inches away, it's an almost daily job of adjusting the lights to stay 2 inches away, but cfls need to be close.

No Title

The plants are in a closet and I've put up curtains and also keep the door closed. I have some foxtailing now as well.

Will the general hydropknic nutrients contain calcium or is that something different i should purchase?

How do you think this will affect the yield? I'm worried these plants are going to die before I can harvest. I've inlcuded some more pics.

Thanks everyone!
