Help my Bubba Kush....

[scrappy]

Here is my Bubba Kush (katsu)...this gal took like 3 months to root...now this...what's happening?....the tips curl and seem burnt....

Bubba Kush (katsu)...in Pro-mix with extra perlite....my mix is per 5 gallons of pro-mix. To that I add 1 cup each of the following:...Blood meal, Bone meal, lime. then about 25% extra perlite...now I've used this mix for years, with fine results...a spike here and there, but very good luck none the less...

nutes:...Alaskan fish emulsion....Earth Juice bloom and meta-k..grandma's molasses...now I used the mix once...but have used plain water ever since...As of 3-22, I have flushed the Bubba....any input is welcome...

see I don't know the ph or ppm....I realize that would help...but I've been growing for 6-7 years without one...but with these newer strains, I might invest in one....I only feed it once...about 2 weeks ago..plain water ever since..I have many other strains in the same mix and they are fine...just the bubba....thanks....

Hey scrappy , I say feed her pretty good. Bubba likes cal mag alot so that might help. Bubba can take whatever you throw at her. It's definitely easier to underfeed than to overfeed her. I didn't use a PH meter last grow since mine broke but will get a new one, sometimes there's lockups and the ph is at fault. Let us know how htings turn out, I'm sure your Bubba will be back to normal soon. Take care.

Hey Piff...thanks for the input...need to go get some cal/mag...I hope she comes back...really wanted this one ya know!!!....she took so long to root and now this crap...It's growing, but the leaves....aaahhgggrrrr!!!....lol...happy growing

Plant looks like she is fryed I would flush her with a lot of water if I were you

 

[scrappy]

thanks stitch...I knew I could count on you...I flushed her about 2 days ago

 

[scrappy]

OK....I fixed the burning tips...Now I have a whole new problem....the leaves curling up!!.... ...it really came on after a recent watering...just plain water...no nutes..just plain water....as you can see all yhe other plants are fine..no problems...many different varieties, but only the one Bubba....Help!!

3 Months to root? I think the key to your problems lies here - healthy plants do not take 3 months to root - they'll root out a container within weeks. Your plant probably isn't root bound, but it's used up all the nutrients available in your soil mixture.

You're now pounding it with liquid fertiliser which is simply building up an excess of salts in the rootzone. The look of your plant is consistent with an large salt buildup, particularly if it's been in the same pot for 3 months.

In my opinion you now have two choices. Firstly, simply repot it into a larger pot and start feeding it plain water until it recovers, or secondly, remove it from that pot and root prune it. Chop off about 1/4 - 1/2 an inch of root all around the outside and then repot it into the same pot with fresh soil, again feeding it plain water till it recovers.

Your last photo showing the leaves curling upwards shows the plant desperately trying to conserve its moisture, due mostly to the reverse osmotic process that draws water out of the roots rather than into them due to the high salinity of the surrounding root zone.

Why extra perlite? All you're doing is removing nutrients from the soil by adding extra perlite, is Promix so poor draining you have to amend it with extra perlite to improve its drainage?

Why blood and bone meal? These are so slow acting and releasing they hardly make any difference at all.

Use dolomite lime by all means to buffer the ph and help slow release mg into the rootzone, but skip on the extra perlite and blood and bone meal.

Thanks for the reply tree&leaf...True I've never had a 3 month wait on any other strain to root, always within weeks....

I'm not pounding it with fertilizer, I only hit it one time(my normal dose); like over 1 month ago...It has not been in the same soil for 3 months...it's been transplanted once...

I plan on transplanting soon...hope that helps!!

The leaves that are curling upwards is heat stress BIG TIME, the plant is trying to protect itself from the wattage of light and by curling it trys to save the moisture on the leaves before it dries up so curling is a plants mechinisim to protect itself..... move the light up, damaged leaves won't recover, but may slightly uncurl some of the ones that is not badly curled up.

I also thought heat stress...But why are all the other plants not effected at all...It's in the higher 70's, not to out of wack....The curl came on after a watering....It's just weird, all the other plants are in the exact same soil mix...all watered with plain water...the only plant in the stable having problems is this Bubba...I've used this "BOG" mix for years without problems..and with good results IMHO...

Now that she's drying out the leaves are uncurling some....gonna transplant her today...

 

[MynameStitch]

Because not all strains have the same tolerance to heat, nute amount and such.
Bubba is a little touchy to heat it seems like.....

It's not the temps themselves, not room temps; it's the dry heat the lumens produce from the light intensity.

I used Bog's mix myself, it's not that or anything else you have done recently.....
notice how the lower you get on the plant the less severe the curling is.....

move the light up or if the plant is propped up on something remove the prop.
When you grow out different strains things like this tend to happen unless you know they can grow in the same conditions the mixture of strains you use.

If you don't move the light up the plant will lose most of it's leaves and will grow very slowly; with the leaves on there now being affected your bud growth will be slow due to the size of the plant an d the amount of leaves lost if the problem is not soon corrected.

Now that she's drying out the leaves are uncurling some....gonna transplant her today...

PLants don't curl up from a good watering, if anything they will droop and curl under not over.

ASk anyone who has had heat stress to look at the picture you showed; guranteed they will say heat stress just the same as I did.

WHat size pot is she in and how big is this plant?

Will do Stitch......I totally repect your opinion,and advice and will do this asap...Thank you so much...You must spread some Reputation around before giving it to MynameStitch again.
