Howdy do folks. Hope all's growing well on your side

Sorry for being absent all week. I buggered my tablet device and I don't like to log in on any other device, incase I leave a trail of evidence that the old Bill can follow.

Anyway, where were we?
Yes! The deficiency.
The sour diesel was showing signs of nutrient burn, without any change to the nutrients. She was also displaying white tips on the fans and slight colour change to the borders of the leaves. The Blueberry was also starting to lose the colour in her borders.

Here is the blueberry before and the next picture is the SD before

So, after all the wonderful advice off you lot, i bought some calmag.. I gave the SD calmag and a PK boost and I only gave the BB a PK boost on Monday
Both of them are fixed, or on their way to being fixed
Heres the BB

and here is the SD

They are getting healthier by the day..
So after a process of elimination, it looks like the PK boost was the one that was needed the most. I'm not saying the CalMag didn't help the SD, as she's never looked so healthy. But after doing a bit more research I found out that a potassium deficiency causes a burn on the tips and lightning of the margins .

The Cabbage food they get normally is low in potassium, so it seems to make sense..
If it happens again, i will repeat the process. But this time, I will give one just calmag and one just PK and see what the results are.

Oh! But whilst fixing these two, I've broke the white widow. After a feed of base nutrients, calmag and PK, she lost all her colour within 2 days. I know she's getting old and tired and will naturally lose colour, but this happened as soon as she was fed

Shes pretty sparkley and sticky, so I'm not too worried. I will check soil PH like @Verbalist mentioned, so I can rule that out. anyway.. she's only got a few weeks left; hopefully she can keep enough green in her leaves so she can photosynth-a-thingy properly.

The BB and SD are now officially in flower. They have their party hats on.
Heres the BB

So, that's it really.. it may take me a while to catch up on all your threads;
but I will.
Oh!! Day 8 of no smoke. The wife is feeling it more than I am, as she's had to go back to her tramadol for pain relief.. they make her all sweaty and anxious, so not good..

I'm just slightly fidgety. It's the taste I miss the most.
Who am I kidding.. I miss the mellowness. My mind is racing a million miles an hour. Full of great plans and no inclination to do any of them.

Ooops!! Im rabbitting again.
Anyway. That's it folks.. as always, i appreciate you all popping in and giving your advice and support.
I will see you all on your side

Take care

Excellent Squig - good work with the camera too

 

[Rexer]

Looking great Squiggle!

You're going to be having a low tolerance again, and great smoke soon enough, so that's something to look forward to.
For the Mrs, i wish there was something I could say. I've been on tramadol, it's not nice, and i hope to never be on it again.
Send her the best wishes from across the seas
Wish I could offer advice on the plants, but I know nothing on soil. All I can do is

Thanks for the compliments and we'll wishes..
This is a truly pleasant forum..
Thank you

Thanks mate. The camera skills are down to you . You told me what all the settings do. I Just used it in Numpty mode before.
So thanks for that

She's received the best wishes mate. They came through loud and clear.
I hate to see her on the tramadol. Her tolerance increases quite rapidly and she needs them more and more.. like you said; 'Soon enough' she will have her home grown medication.

Thanks again for popping in mate. Appreciate it.
Oh! I know nothing about soil either. So join the club

Hi folks

I'm thinking about writing that review, that this journal is really based on. Title says it .

But, I've found a few issues with the light; well not issues, just design features that don't really work for me.
I don't want the report to sound like I'm complaining; anything but!
It's an awesome quality light; Just things could be different to improve the users experience with it.
It's insanely powerful, as I showed in the home par test thingyHere.
Its results were impressive.
It is a lotta light for a little loot..
It's got all top of the range components, meanwell and Samsung's things..

These current plants I'm growing, are doing great under it.
Apart from at the beginning, when I was frightened of dialling up the power, incase I burnt them. Anyway, they ended up stretchingHere.
But once I got my own par and lux test done, (based on the position of the dimmer) it all went smoothly after that.

The main design flaw was not having removable drivers.
The drivers kick off quite a bit of heat and so do the LEDs. If you had AC or it was winter, it wouldn't cause much of an issue; but I was testing it in the middle of summer and it got as hot as the surface of the sun in there. (Slight exaggeration) 50.C on the heatsink..
I couldnt afford AC, so I had to remove the drivers and place them outside of the tent. Pretty simple jobHere and I'm a caveman. "If it won't work after hitting it with a hammer a few times, it's broken"
So if I could do it, most people will be able to also.

Anyway.
Thats the only issues I can think of. The drivers and no info on what the dimmer does.
It's just says 20 to 100%
So providing a rough guide to what wattage and par it's putting out at a certain setting, would be helpful.
Oh! And the removable drivers would be a nifty feature.

So, all in all, I'm happy with it. It's working and I know it will keep on working for a long time, it's got some of the best components out there..

Anyways I will give it a rating out of 10

And the results are in....

I will give it somewhere around 7.8.
if they do those little mods, I would give it an 8.5
The only thing stopping full marks is, it's not sexy!.. it needs some funky colours or shiney bits on it. Oh! And free stickers.

That was another thing,, the box it comes in, wasn't very descreetHere
They did say they were going to address that..

But, this could just be me. If this light were in a larger room with better extraction, then the heating wouldn't be an issue..


So that's it folks.. I started asking for advice on how to write it and it wrote itself.. thanks for reading.

All questions will be answered with a guess!!!

Thanks again,

Squiggz

Very nice review Squiggle! You're doing a great job with the light, and showing what can be done with it. I liked how you addressed the issue with the drivers heating up. Again, well said all in all

Thank you. Do you think I should make it public? Or would that question be better directed at 420?
It may put some people off buying it and I don't want to damage the companies reputation..
But I don't want someone buying a light with 7.8 when they are expecting a 9.1

 

[Rexer]

I'm not sure on the question to be honest. Once written into your journal it is public? Thats my understanding, but I could also be way off.

Thanks for getting back to me. I was going to post it into the review part of the forum. Sorta sticky..
But if people search for it, they will find eventually, so your right
Thanks again mate appreciate it

I'd keep schtum - basic rule of blogging 'If in any doubt, don't'
Your excellent review is there for all to find

 

[Verbalist]

Glad no major damage happened!

Looking at the newest pics some of the plants still having a bit weird symptoms. I would stil guess the pH issue. Since too alkaline or acid medium might trigger nutrient lockdown. Plant wont be able to absorb nutes from the soil and its able to only benefit from the inmobile nutrients which are already ”stored” inside the plant.

If you fed them with some additional cal/mag and PK-booster that probs might have raised the pH value back/close to the normal.
The chart below indicates acid and alkaline pH values for cannabis and also shows that Cal, Mag, P & K all have a potency to raise up pH value. (Usually pH is too high/alkaline in soil, but Ive had pH close to the 5.5 after flushing my prev plants, so acid soil is isnt impossible)

And Im guessing something similar might have happened with your white widow..
Leaves definitely look like theyre old yes, but more likely having a Mg defiency (yellowing leaves and green veins are shown: most common symptoms)
And you said you just fed them also with Cal/Mag… and Magnesium is a mobile nutrient so plant should absorb it fast. Also Mg defiency usually first appears on lower leaves, but in your case it looks more like upper 2/3 has the most yellowish foliage(?) Which is weird…but incorrect pH or big ups and downs on pH usually causes the most weird symptoms.

E: as the plant matures during the flowering perioid, it usually becomes more ”picky” about nutrients. And if the soil has a lot buit up salts that may lead to nute lockdown.

I definitely would test run off and soil pH first of all.

Thanks mate.. if in doubt, don't..
I should adopt that saying into my life..
I always "do" first and ask questions later.. if there was a huge red button in front of me, saying "do not press" I would press it a thousand times just to see what happened..
Thanks again.

Cool chart. Thanks for all that info.. just printed it out for my diary..
I certainly will be checking PH a bit more closely from now on..
Thanks for taking the time to write this mate. Much appreciated

Got to be honest the my bar light owns all my lights heat wise when the driver is of.BUT with drivers on the vipar
series handles the heat much better than any light i have owned.Shocked me tbh the build quality of vipar lights
i expected much cheaper feeling/looking lights till i bought one due to the price.Only down side is the fact you cant remove the drivers easy.They missed a trick there like most companies more worried about health and safety or broken drivers and extra cables money saving?

Hey mate. Sounds like advice I should of been given 12 months ago.

I’m not like that with Red Buttons.. If someone said to me..
Hey Bud, don’t press that button..
I’d be like.. ok.
But if someone said …
Hey Bud, somewhere in this room we’ve hidden a red button, don’t press it..
I’d be …Mmmmm. Gotta find it first…interest has been piqued ..
unfortunately though..I’d probably be pressing all sorts of buttons en route..trying to find the red one..
Peace an buds matey

Good advert for viparspectra on the heat output and the quality.
I think most light companies are starting to design lights with removable drivers now, so things will eventually change with viparspectra.
when you think of it, high powered LEDs are still quite new in the growing world. They are changing rapidly.
No doubt in the next few years, we will all have a collection of lights, like old trainers.. yes they are still usable, but we all want a brand new pair

Hi mate. Hope all's well?

Ahhh!!! If you had read that review, would you have bought the one you've got?
I know we got them cheap. But would you have been disappointed if you had paid full price?

Oh! The button. After all that searching for it; you still wouldn't want to find out what it did?? curiosity will kill this cat..
If I see a sign "WET PAINT" I've got to touch it to see if it's wet
