First grow little help plz

[Justaguy]

Hows it going everyone, this is my first grow and I've been having a problem with yellowing for sometime I've tryed alot of different things so far with no luck.

I've got some pics here to show, and am hoping I can get some help with thats going on, I have a pic of the whole plant and some leaves, my medium is perlite and is running in veg 18/6 under a 400w light, just put the watering system in a few days ago, all help is appreciated.

 

[Rosy Cheeks]

Tell us a bit more about your grow Justaguy. What nutrients are you using, at what strenght, what ph, things like that. Has this plant been like that from the start, or at what point did things start to look bad? What 'things' did you try, what strain is it?

 

[Guest]

Perilite only??

NO NO my man,it can work but dont be scared
to put some peat or coco in there too..........
BIG DIFFERENCE,not to late pull it up an mix something
into the perilite to help!....soil is BEST all natural!!!
Welcome to IC mang good luck!

 

[Justaguy]

Well I've tryed different things like epsom salts ect ect because most of its life its had yellowing of the leaves, is a clone, not sure what strain was never told I can give some picks of what Im feeding it, will do it later tonight or tommorow, ph is around 5.8 testing strips are hard to read but it wouldn't be far off. was also told I had it too bushy and it couldn't feed itself and to trim it, thats why not heaps of leaves, but whenever it grows any leaves lower than that on there, they instantly go yellow and die hope this helps
thanx again

 

[Justaguy]

Here we are, I feed it 5ml of grow a and 5ml of grow b per ltr of water, sometimes I use nitrozym. Incase you can't see the grow a and b are both N 12.2, p 2.3, k 10.8, hope this helps.

Ps. Says contains fulvic acid, Thiamine (B1), Boric acid
Sodium Molybdate
Mn, Zn, Cu
KNO3 CaNO3, MgSO4
NH4NO3, NH4PO3
KPO3, K2SO4
Also what kinda of mix of peat and perlite do I want? 50/50?

 

[Justaguy]

Come on guys I know you can figure it out
See, im new to this and not sure on what information is useful and whats not,
If you need any extra info just ask.
The food is 1400ppm
and not sure if this is useful or not but, the clone was taken from a friends plant that was harvested and very bragged about weed (rightly so)
But myclone was taken along with 2 others, which my friend intended to grow for himself, which both unfortunately had big problems with yellowing and staying very sick, apparently there was also a power out that caused the his clones to turn to bud and after trying all sorts that he'd had suggested to him they had to unfortunately be "put down".

Not sure if this helps, all replys appreciated.

 

[Core]

with those numbers ....could be you are expirience a P def....

btw is your ph meter calibrated?

 

[Justaguy]

Hmm maybe, thanks for the suggestion either way, been refreshing this page constantly waiting for an answer , I dont have a ph tester unfortunatly just testing strips.

 

[Justaguy]

Oh I keep thinking of things I should tell you, when my friends clones died he decided he'd had enough and quit growing, I was using nutes ect that he was supplying me and now have obtained the rest of the bottles from him, its what was used on the mother plant which had no problems with deficiecys. also as of a few days ago I've even obtained his hydro setup.

 

[SinsemillaJones]

Okay, I'll try.

Okay, I'll try.

N 12.2 at 1400 ppm sounds like a lot of nitro for a little plant. I'd knock it down by at least 50%.

 

[Justaguy]

Hmm maybe, the thing I dont understand is how could a clone have deficiencies (or toxicity) in the same medium with the same chemicals and ppm and everything. even smae watering system.

 

[SinsemillaJones]

Is the clone as big as the mom?

Is the clone as big as the mom?

If not, it can't handle as many ppms. Nute strength is dependent on the stage of growth.

 

[Justaguy]

Have put a little big Of fish emultionin with food and will see how she goes, if no improvment I will try lowering food,
Also I think I was reading something about ppms being different depending on where you are in the world?

 

[SinsemillaJones]

Why fish?

Why fish?

Is there a reason, or are you grasping at straws?

 

[Justaguy]

It's just this problem has been going for some time, before I even put it on these nutes, I've read so much trying to fix it but my efforts so far have been fruitless.

Fer god sake's man, test the ph and correct it before adding anything! You are not accurate enough with the strips. I recommend a digital ph pen. The milwaukee ph40 is a good mid priced pen that works. ($70) You will never gro mj the way you want if you don't understand and master ph. Some may get lucky that circumstances are good to grow their plants without knowing ph, but if there are problems they are screwed. You must know and control ph. It is the key to proper fert availability to your plants.

You've got a good mag def happening there, pale green with dark green veins, among other issues, you need to accurately test and control your ph.

SensiJones is right, way too much fert for a newly established plant. If your ph is out and your nutes are locked, and you've kept adding nutes, you are most likely seeing fert toxicity now.

Flush them with plain ph adjusted water, try upping to 6.5 (runoff measurement), no nutes or additives, and watch the new growth for healthy signs. Old damaged leaves will not heal alot of the symptoms. If the new growth looks better and the plant improves generally, start with the gro at half strength. 10ml per L of a fert that strong is killer. I use 5ml/L BioBizz Gro, and it is a mild organic fert (NPK: 1.8 - 0.1 - 6.6) and that is enough on my big, established vegged plant that just flipped to 12/12. No N def at all, plenty of nutes and as a matter of fact, next watering I am flushing my moms and clones because they are starting to see a bit of fert burn from this fert schedule. I am following the recommend sched from BB, and still have to customize it for my strains/wattage/techniques etc.

Good luck with that.

The worst thing you can do is lose patience.

The worst thing you can do is lose patience.

If you start throwing stuff at your plant out of frustration instead of logic, you'll probably hurt your plant even more.

Fish emulsion is usually about 5-1-1, so if Core is right about P def, it won't really help. And if I'm right about N tox, it'll just make it worse.

Good luck.

(Wups, I didn't see Pete's post. Very good advice!)

 

[space cowgirl]

Personally, I've had nothing but failure with hydroponics. Maybe try soil and see how it goes?

 

[Core]

ii'd like 2 remind that he is using perlite as a medium...good post though pete

and again with those numbers its realy possible that your Nitrogen doses are 2 high also..did't even think about that...

 

[HeadyPete]

My bad, I guess that qualifies as hydro. What do you recommend there, 5.8? I don't do hydro.

Thanks Core!
