Hi there, thanks for the help in advance.

The right hand plant seems to be a lot worse than the left hand one.

These two girls have been in 12/12 for 26 days now, they had a slight change of color on the bottom leaves a week or so back but now they're getting worse.
I am feeding Organic nutrients every second watering with 6.3-6.5Ph'd water.
They're under a 400W HPS light and growing in soil.
Lights off temps 55-60 Fahrenheit and lights on 73-78 Fahrenheit.

My run off water i haven't tested in a bit but last time i checked it was 5.5 so i did a flush and haven't really checked since but i suspect it may still be low.

If there's anything else you need to know just ask please :)

Thanks again!

Need more info... Looks like over watering that's messing your ph up around the root zone which then is giving you some lockout. Would love to know what your feeding her, soil, ph and ppm of your water, humidity and temp in the grow space you know just the some vital info....

Let your plant dry almost till the leaves are soft and drooping. The give a really good feeding with about 25% runoff then you should be back to normal. Don't over nurture your girls. Water every three days....trust me

To say water every 3 days is not gonna cut it!
There are no set times as far as days,because peeps use different size containers.
Learn the plant,before and after watering,I go by the weight.
Very simple!

I only water every 4-5 days (they're starting to drink alot more now though) as its winter here and even with a heater,rice,damprid etc i can't get RH below 50%, sits anywhere from 40-60% at the moment.
Last two watering's I've used half strength of the Nature's Own Super Bloom with the water PH'd to around 6.3-6.5. Not sure what to do next watering.
Feeding organic nutrients called "Nature's Own Super Bloom".
I have no idea what PPM is nor how to test it.
I've already stated the temperature of lights on/off.
Soil is also called Terazilla Growing medium, guy at the shop said it had 2-3 weeks of nutes in it already.

I agree with pot grower ph some h2o and flush. Do yourself a favor and by some cal/mag. 5ml per gallon every time you feed her.

So the run off water actually matters? water going in is correct but the water that comes out is not, i will try find where to buy cal/mag whatever that does.
Are you sure this is the problem though?
Any other suggestions from advanced growers?

Use Calmg definitely as it adds calcium and magnesium which are needed for healthy plant growth and both can get depleted, especially in soil. Also I would cut back to every 3rd watering for feeding. What's your ppm? You problem looks like too much nitrogen to me, plus your leaves are beginning to claw, which is another giveaway I don't put much faith in testing run off, because all you are really testing is the feed water again. You really need a soil ph tester to get an accurate reading of your soil. Good luck.

A PPM tester / or EC in simple terms measure how much food is in your water. Without this info you are shooting in the dark as far as your nutrition level is concerned, and I think you are finding now out how important that is.

Okay, i will get some of that tmrw hopefully.
Also will have a look for a PPM tester, if i left the plants from now till harvest what would happen etc, would it ruin my grow or?

So i bought some stuff called Earth Juice Micro Blast, It doesn't have cal in it though i don't think?
The guy at the shop said our Nz doesn't have cal/mag products..Bout to give them a watering with 5ml's per 4 litre's as it says on the bottle.
Also went and got some better water from a brewery which has more lime etc and better PPM apparently.

Will this product suffice if it doesn't have cal in it?
