New here new grower

[JLAM851006]

Hi everyone boys and girls and all other gender!!! I have been reading some tread here for mostly three years!! I started growing last year I have my first two grow that's went without any problem. I'm now on my third grow and I'm growing some White Widow x big bud by female seed ... I use the Canna lineup without using the Boost... I'm actually really happy with the whole lineup and I never had an issue with this brand but since I started this growth I keep having issue with the plant... right now I'm feeding them has 500 ppm growing in Coco having a 5.8 ph and the plant are in veg for now 4 week and for the last 2 weeks they stop growing and the turns green but much more light green ... they also start to show some little brown spots I can't tell know what I'm doing wrong and this is why I'm asking.... normally I will read this read and find by myself but i can't find .... please help me I would not like to lose my grow.... somebody told me that it's might because I overwater them... But someone else told me it's imposible in coco .... Anyway PLEASE HELP ME !!!

Are u using calmag, looks like some calmag issues are tearing it's head, well calcium anyways

 

[JLAM851006]

no i'm not using cal mag ... the guy at the hydro shop told me i won't need it with CANNA lineup

 

[Chris Scorpio]

Tap or RO water

Looks like ya need calmag

 

[JLAM851006]

Tap water

 

[Chris Scorpio]

Well ride it out I guess, see what happens

 

[JLAM851006]

What do you mean by ride it all ? Sorry my first language is french

 

[Chris Scorpio]

I'd say you need some calmag, but you can choose your course of action on moving forward

Calmag is a pretty common issue, and when using lower strength nutes, meaning less than 100%, added calmag is usually needed

 

[JLAM851006]

Ok ! I understand ! Ill go buy some tomorow ! And try it out ! Should the plant become greener fast ? Should i see a diference ?

 

[Chris Scorpio]

Bad leaves won't get better, but will keep it from spreading more

Won't happen over night , so give it a few days to fix itself

 

[Bilbobudkin420]

If they say your line up wont need it theres some calmag in there. (Wont hurt to have some on hand though as @Chris Scorpio said) She looks a bit light in colour aswell so is probably a little hungry all together not just for calcium. Its not a huge problem or super hungry but yer kick up your feed a little bit

 

[Bilbobudkin420]

Are u feeding everytime or doing waters in between like soil? Coco needs constant feeding as its basically hydro.
Yo @Preston9mm what ya think?

 

[Bilbobudkin420]

Oh amd just so you know it doesnt look overwatered to me but it is possible to overwater in coco. Hard to do but possible lol

 

[JLAM851006]

I feed every time . i test my run out all the time to make sure i stay around 550 too 650 ppm .... I use canna a and b and i use rhyzotonic . i follow the canna chart ... I done that for my last 2 grow and everything was perfect never had an issue actually but since i started those from seed they seem slow a bit but really they have almost stop growing for 2 week ... And they a really light green and now they start having those brown spot .... But they were light green for the last 3 week ...

Sounds like it could just be a hungry strain my friend.
As i said though it doesnt look terribly hungry just a bit.
Just curious but what are your room temperatures saying? And also your water temperatures?

 

[JLAM851006]

Room is always at 75 and humidity around 50 to 55 water is around 72 ... I up the ppm 2 week ago around 700 ppm to see if they would get better but not difference

 

[JLAM851006]

I run a 1000hps hortilux and when the light is open leaf look a lot more like if they turning yellow

 

[Costello]

Bring that ph down. And don't feed everytime...try every other time. You could have nuit lockout.

 

[JLAM851006]

So i end up adding cal mag and cranking up ppm as what you guy's were saying . result !! Everything is now perfect ! All new grow are greend and healty !!
