Sensi Star is not Happy :(

[OsWiZzLe]

5 days into week 1 of flowering...My PPM is 1700...Co2 1500 PPM....Run Off PH is 5.9....Medium is Canna Coco along with their Nute line up...I'm doing an Ebb and Flow set up ...flooding twice a day for 15 min each...i just recently started this 4 days ago...b4 that i was only feeding them once a day and flooding for like 30 min..the container size is about 2.5 gallons...I flushed them last night with Tap Water and Clearex...i did not adjust the PH in the tap water though...please help...i vegged these girls for a whole month..and now they're showing mad issues...are my PPM's too high?

i'm growing out some sensi star right now in dwc, and yeah she's far more nute sensitive than any other strain i've done, the next most sensitive would have to be white widow, and even she liked a good bit more nutes than the star...

i have no experience at all with any method other than dwc, but i'd say just back it way off and work up slowly. that doesn't look too bad, mine burnt pretty badly at 1100 ppm (.7) but recovered nicely. good luck, lemme know how it goes.

Hey bro... I use canna coco.. i do a run to waste... I would NOT have ppm of just A & B higher than 900 TOPS!!

Those plants look like an IRON def to me... but what I would do it just give em PH water for next 3 days.. PH it at 5.7 one day.. then 5.9 then next then 6.1 the last... then mix up some new nutes at like 8ml per gal... and PH it to 6.0 start going again..
If it is a Iron Def... like I think.. it will start greening up even b4 the plain watering are done... like 2 dayz u should see the new growth coming out nice n green..

When u water with the plain... drench the suckers... your cleaning out the soil..

Let us know how it goes

Peace

thank you guys for helping me out...boy i have been trippen today....

Does it matter if the water is tap or distilled..as long as its PH adjusted?

Should I use Clearex? i have half bottle left over from last night..so after 3 days start giving them nutes again? Should I continue with the same watering schedule?

Its not iron its a severe magnesium def....


clearly thats the problem.....

Here is a post with an iron def.....

see post 14 for a good pic......

Here is how to recognize the difference......

With an iron def you should see outer green tips and inner leaf chlorosis....

with severe magnesium def its the opposite....

outer chlorosis and inner green....


also when its severe magnesium def you should see signs of that before the deficiency gets bad and causes the severe chlosis you see here...

that you can clearly see in pic 1 here.....

didgeridoo....what do u recommend for solving my problem?

 

[swampskunk]

didgeridoo, good call man. /bow

oswizzle, dissolving some epsom salt is a good way to get some mag to your babies....

 

[Guest]

Stay away from the clearex....

If you have some epsoms you can foliar feed for a couple days......

Your problem probably was quite simple to begin with and you complicated things.....

Feed your plants man..... you probably were feeding ok at the start and as the plants grew you didnt increase the chow enough.....

 

[Guest]

Just one final bit about why iron and severe magnesium deficiency take on the characteristics they do.....

The reason stems from the fact that iron is considered immobile....

where magnesium is mobile........

So iron def shows as green leaf tips and chlorotic inner leaf.....

The plant in effect runs out of iron as its making the leaves.... as such it starts out green then nearly immediately the chlorosis starts......

Since iron is immobile it cant pull iron from older existing leaves......



Magnesium is mobile.... so the plant can pull magnesium from existing leaves....

this is why the tips are chlorotic and the inside green.....

In general while magnesium is mobile its not as mobile as nitrogen......

with nitrogen the plant uses sources at the bottom of the plant....

with magnesium it takes from the next node down normally......


Too bad my friend stitch isnt around .....

this would make a good addition to her sick plant guide......

Back on OG I recommended several of the pics for her guide.....

Oswizzle-

Problems with Sensi Star too? Did you clear up the problems with the Silver Pearl plants?

I use Canna Coco products too. I also use Advanced Nutrients SensiCal, to supplement Magnesium, Calcium and other micro nutrients. I add 5ml. per gallon to the usual Canna regimen: A & B, Cannazym, and Rhizotonic. I keep my ph @ 5.8 and my plants are hella healthy.

900 PPM tops?! I think different strains have different requirements. I am currently growing Green Crack and am using 15 ml. A & B per gallon + the 5 ml. of SensiCal and my plants LOVE IT. My PPM at week 3 of flower is 1550 PPM. Watch your plants, they will tell you what they need.

Go by IGS and have them hook you up with a bottle of the SensiCal. DO NOT add epsom salts to the Canna Coco.

peace.

I don't think this is lack of magnesium. Looks more like a micronutrient problem...your growing points are most affected.

 

[Guest]

Hey black velvet....

You posted here then deleted the post.....

You in effect were holding this guy hostage.....

Saying you knew exactly what it was and wouldnt say what.....

A childish little creep....

Youve been banned before....

You should be banned again......



You had your chance now is the time to stfu......

 

[Blackvelvet]

And you were telling him the wrong thing...

 

[ninfan77]

So it was Fe or Mg deficiency?

 

[Guest]

And you were telling him the wrong thing...

Alright you prick..... go for it....

before you said you knew exactly what it is....

go for it......

tell us exactly which micro it is......

even though below this chlorosis there is clear evidnce of increasing magnesium def......

maybe you want to try zink????

clearly not zink.....

but clearly something that effects chlorophyl......

Great answer. Probably burned the root tips off. Ebb and flo subirrigation requires about 1/2 as much ferts compared to watering overhead.

rotflmfao......

good answer black velvet....

your answer brings you home......


you being the expert on stump remover......

so come on black v.....

now nothing???

whats up with that???



which one???? you creepy little prick....

 

[Guest]

Black velvet.....

I dont think you realize how pissed I was at the post you deleted....

You said you knew exactly what the deficiency was... but wouldnt help....



Do you deny it?????

I would have banned you again on the spot.....

just for being a prick....;
