It looks like they are badly overnuted to me. This has likely stunted them, and during a critical phase of flower the chances of them filling out much more is unlikely.

 

An EC of 2.2 is really pushing it, I never go above 2.0 and ideally keep it at 1.8. I suggest you flush and bring it down.

2.2 is pretty high; I'd suggest nute burn also. What's your pH?

 

Could also be a strain issue. Save some money on the AC if you like and let it kick in at 28 to bring it back to 26.

ph at 5.5, im not using high level nutrients, im at 1/4 strength nutrients as to not over do it,

the strain is church, ideally, im thinking of going back to widow not happy bout it but i guess atleast i know its traits.

 

any way to save this?? and just get it a little more tight, cause one that broke a wk ago, is like spindally as all hell...no weight to it, not tight....looks pritty shitty

You say you have an E.C of 2.2, then go on to say your only using 1/4 strength nutes?

 

Also do you let the PH drift up before bringing it back down? 5.5 is a tad low to run all the time.

What light have you got there?

[uka]

600wt hps sontigro light, yea i dont really adjust it everyday, i kinda let it go for like 2-3 days and then ill check the ph, but thats generally when i have to top up the water a bit, so i have to readjust it cause the water outta the tap is like 8.5

maybe my ec pen is off, the guy at the shop calibrated it so maybe im way off the mark..

1st things 1st, 2.2 is not 1/4 strength, it's over fertilise if anything, 2.0 is also the highest i will ever go, to help you understand the importance of ph levels i've found you this, http://4.bp.blogspot.com/_97rXyvezeik/Sg2xEr8Sz8I/AAAAAAAAADk/rTBKrTJ1Zgs/s400/nutrient+chart_hydro.jpg http://hydronutes.blogspot.com/

if you look there you will see that at 5.5 your plants will not be talking up all the necessary nutes for a good healthy life as they are only avail for them to take from 5.8 throught to 6.2 really, also what are you topping your buckets up with??...you should only use ph adjusted water for up to 50% of the volume, then i suggest a total replenishment of all nutes and keep ya levels at the bottom of each backet if possible, all this works for me

[uka]

the water i top up with, i have taken out from tap, let stand for 24hrs in open area for chlorine evaporation, as suggested by one of the guys on here, i adjust after ive mixed it all in... ive copied that table, so ill re adjust the ph, ive done a flush, fresh water no nutes, will adjust to 5.8 but ill have to get the calibrater stuff on wednesday...any chance of saving this, or is it pritty over n done...??
