Help please . Pretty please.

hey Will-- How far away is the light, and what's the temps and RH in there? And what are you growing in?.... thanks for the normal light pics, much better! I'm with Red here, this looks like P defc. to me, maybe Ca defc. which can have similar looking symptoms sometimes... likely a simple lack type deficiency given what boosh you have there-- nice! But, off-pH is always a possibility, and without the right tool to get it, you're left with the rather dubious run-off method--(Accurate 8 soil pH probe is the ticket!).. a crude estimation at best; I tend to rule off pH out because of the overall look of the plant, and the light feeds,...
Oh, the Density Ca-Mg, rings a bell,.. does it have a high N content? Like 4-0-0, 6-0-0 (this is a lot for a supplement BTW)....It might have been part of the "hidden " N sources contributing to the earlier N-tox',... So, like Red said, tinker your nute ratios some to elevate the P some, and look into an alternative Ca-Mg product that's no more than 1-0-0,... GO CaMg+ is a great choice ... it'll take a few days for things to halt most likely, so if you see progression meantime, that's normal,... let's see what else might be here after you get us that info....

Ok.. this is the one and only time it's leaving the tent as it's quite hard to manoeuvre.
Hopefully you can see on the pic what's happening.
Thanks in advance
W.

Nice pics! Can you take them out again, but this time turn her a little more to the left? :smoking:
Kidding, thanks for doing that, I know it's a pain. Reps
Great catch by Waira, too, could be some Ca def as well. And amen to CaMg with no N added.

@Waira @Renaissance Redneck and others.
Thanks for taking the time to help ,it's appreciated greatly.
I'm gonna have to hang my head in shame here and say that I don't ,and never have ,checked PH on this grow or my last . I figured that with the Scottish loch water that has a ph of 6.8 and using AN ph perfect I wouldn't need to.. silly I know. Environment is difficult for me as I'm growing in my shed in Scotland so at night time temps can drop to 19 in the tent .up until now though things have been going very well . It just seems this one plant needs more from me . I've got plates of rice in the tent to hopefully absorb moisture .A bit stone age but does work I think.
The HPS is as high as it can go in the tent ,growing in Plagron light mix.
I haven't done a flush this grow yet . I was going to but because I backed off the nutes I thought I'd just keep going for it . Is there any extra additives you guys would recommend for a tree like this? Only my second grow so still very new to it all.
I never even considered density calmag to contain so much N. I've looked online but can't seem to find the complete ratio of its ingredients. I've been adding 20ml every 18.5 l of water since the beginning..
Go easy

Never underestimate the power of simple. It (rice) likely would outperform some fancy chemical desiccants that cost more.

No flushie mate! No need, an unnecessary stress to the plant,... I think Amazon UK has the Accurate 8 (Control Wizard products), or the equivalent -->hsoil: the long probe is the model I'm referring to,...
OK-- the deal with self adjusting nutes applies only to them in solution, not after going into the pot,.. too many other significant contributing factors in there... I forgot to ask, what specifically are you growing in? Biobizz or something? ... night temp is fine; if it was down around 13C, then some slow uptake and transport could cause defc. symptoms,...

Apologies. I smashed my phone screen and have just got it fixed . I don't log onto this site with my laptop ( paranoid I know).
Thanks for advice everyone. The big girl still looking lethargic in a way.This problem ended up affecting a lot of the leaves . I backed off N and added more P and K then started I went up to 3/4 strength nutes which seems to have helped but not sorted so tonight I've upped to full strength on the bloom nutes for the big one . She's budding fine and there's plenty colas on her so I'll just keep going and see what happens. I've got a long probe PH meter on route ,kinda hoped it would be here by now. I had to wait till payday

fekkin' technology! ... sounds good mate, just keep an eye on those tips for signs of nute burn,... now is when it's easy to over-do it as cumulative inputs add up! ...are you using any inoculants? A decent soil herd will help moderate the cycling of nutes,.. a nice treat of molasses/treacle, 1 fat tsp/L twice a week is good for both plant and herd,..

Here's the big girl now . She's back on track but has had a rough time the last wee while . It's looking healthier everyday. Still looked a bit off but it's heading the right way. Lots of weed to come off it if I keep her going all the way to harvest.
