Sick Sensi Star. Help!

[bushmaster113]

Hi,
I have 3 Sensi Star plants which I have been feeding PBP. They are about 35-40 days into flowering. Last wenesday when I changed nutes, in addition to the PBP I added Floralicous Bloom, and less then 1/4 teaspoon of Kool Bloom per gallon.

The other two sensi stars (not pictured) are still doing great. They were all given the same nutes out of the same gallon jugs I mixed them in.

Normally I do not check pH or ppm. pH is always about right with my tap water and PBP.

I have checked pH on the sick plant, it was around 5.5. I pH'd it up to around 6.4.

I do not know if this is pH related though.


Also this plant has a slightly grayish look to it, while the other two are still luscious green

bushmaster113,
I might be able to help, i am an avid grower of sensi star it is one of my favorite plants. I would need a little more info though - like seeds or clones, growing area, lighting, and growing medium, and since i have never used those particular nutes i would need to know the numbers on them. be glad to help if i can.
peAce,

Somehow it looks like a bigass magnesium defiency, how much are you giving them mag?

 

[bushmaster113]

Seeds
300 watts HPS
Hydro

Well, I can get the exact magnesium #s for you if thats what you need. But PBP should have plenty. I could try epsom salts...?

Other 2 plants are doing just fine, and this really doesnt seem like nute burn. I am kinda baffled. It came on within a day and half.

Looks like a Mag defiency, but that is weird because it is only effecting one plant? PBP doesnn't have that much Mag in it, not enough for me running filtered tap water, I have to add about 5ml CalMag to every gallon to keep them from being deficient.

 

[bushmaster113]

Its getting worse!

Its getting worse!

Im beginning to notice effects on the other plants too. It looks like some serious deficiencies springing up!

I just changed all the nutrients out and switched over to some GH nutes I have instead of the PBP.

Here are 2 pics from the second plant which is now suffering

doesn't look like any mg deficiency that i've ever seen...looks sick for sure though. Have you ruled out disease or virus? What about bugs? Have you checked for bugs?

 

[bushmaster113]

Yep Sunnyside, no sign of any bugs. I hope for new growth tommorow. I have played with the pH a little, its good, put in a diff fertilizer, and foliar feeded with the nutes.

Hopefully no viruses or such!

bushmaster,are you growing in soil or hydro?i beleive you overferted looks like an overdose of p or k.if you overdose with p or k it can block out mag,iron,zinc.the koolbloom is a very potent fert,and is a chemical fert which will burn very easy.if you are growing in soil i would suggest a flushing.

it's this comment that makes me wonder...I would have to assume that all plants are being tended to equally as well. A grayish look? That doesn't sound like any deficiencies or toxicities to me...

A flush never hurt anyone

Nute burn..i would also say bringing a plant from 5.5 to 6.4 is a huge shock in itself..you need to lift ph slowly even though 6.4 or 5 is ideal.

 

[bushmaster113]

Here are more pictures. The damage spread rapidly. The other two plants are still doing great. The picture of the damage on the other plant just looks like nute burn now, but it sure started a strange color.


I have the sick plant and a pic of the one doing well besides it.

So is the consensus now to get the sick plant out of all nutes and into just pH'd water?

Yeah sunny it still does have a grayish tint, maybe its just not vibrant green like the other two. But I have examined it with a microscope as well as my naked eye and it does not seem to be a bug. Also the rapid interveinal death doesnt look to be bug caused.

awww.. poor lil girl...

flush her and see if she feels better

 

[yts farmer]

check out your roots.

on a grow i've just harvested,from about week 3 12/12 i thought i had a mg problem as my plants were rapidly yellowing added some epsom salts to no avail and ph seemed to be good so it lead me to think it could be a n or p problem but it wernt those two either it was root rot.

keep us updated bro.

Ok I am flushing the sick sensi star. It appears that whatever the problem is, is affecting the plant in a more top to bottom fashion, that is starting at the top and working its way down.

This pic is of a new sick patch on the other sensi star which are healthy besides this patch., should i flush them all to be safe? Dont want this to spread to the others if its just an over fert problem.

Also the roots look really healthy! Although the sick plant has definitely stopped growing, it drank almost no water last nite where the other plants drank half a gallon.

 

[bushmaster113]

so sad. this plant was awsome three days ago

 

[peach125]

I have always heard that Sensi-star didn't like Nutes especially Chemical ferts.I have always used Organics and Never seen that Before. Good Luck I would flush them it wouldn't hurt. Good Luck....Peace...Peach

 

[bushmaster113]

Yeah im flushing her, but I think she might die either way.

 

[bushmaster113]

I dunno, I geuss it must be nute burn. Weird though that only one plant has suffered. Leaves have basically turned light brown and crispy. I have removed many dead or dying leaves and continue to flush.

 

[Guest]

what i beleive happend to your plant is you overferted with p,which inturn interferes with uptake of mg,fe and zn.you are showing signs of multiple def.hope the flush works.good luck
