Can anyone tell me whats wrong here?

^Only PH test I really trust is when I take soil to the local co-op and have them test it for me.

ya right, cause I want to bring a little baggie of dirt to my local grow shop, spend like 10 buks in gas and 2 hrs talking to a bunch of dumbasses about the dirt im growing my pot plants in. and oh, I bet they do that for free right? thank you for that!! that was the funniest thing ive ready all day...haaa

its a little more practical if you learn how to test your own soil and dont have to rely on some idiot on min. wage just my opinion.

I love all the people that seem to think every problem is cal/mag without even asking what his water source is.... lol

Are you using ro water? If so then it MIGHT be the problem, if you are using a decent plant food and tap, highly doubtful.

He's growing in Coco Cal/mag is needed.

I love all the people that don't even read the medium the guy is using and just spout bullshit.

Well they look good for plants that stop functioning every time temp gets that low 14c or 57 f is too cold. See all the purple in the stems, their freezing to death. Put a space heater in there with a timer. Don't burn the place down.

Peace

Thanks for the replys everyone! Im still thinking its N def, the girls are taking up the nutes and there more than half the weight of what i watered them on sunday so they are thirsty, if i up the A&B from 2ml per L to say 2.5ml per L you think that would be enough? Thats 25ml in 10L then...

The leaves are going lighter from the outside in and the veins are still green along with purple stems tells me its N def? Its slowly working its way up aswell so its mobile.

Thanks

First correct the damn temp,then see how she does ,a plant cannot function right if if its not in the right temperature,nothing under 70f or 21c,the same happens at high temps,actually around 75f /23c they start to slow down as well,you gotta keep them in the sweet spot for your nutes to work right and plant process to happen correctly

Completely missed the post where you said your temps were dropping to 14 celcius. It's most likely your temps. I know there is a graph around somewhere that shows the optimal PH to uptake nutrients and also the optimal temperatures for uptake.

Bullshit. You don't need cal/mag because of coco, where the fuck did you learn that? That's not true at all, if he is using tap water the fact is MOST (not all ) sources have enough in it to not have to supplement.

what is your ph ? over 7 ? purple stems every where . plant mabe locked up cant absorb fertilizer. nutrients
