Hello guys, minor problem I’ve been having in my recent grows with multiple strains so I’d say it’s not a genetic trait. After like week4/5 of flower when my buds have pretty much developed and are just packing weight, they round of lovely at the top giving a nice golf ball like bud and start to get the odd amber hairs/stigmas. They look beautiful and then I start getting like foxtails and really thin whispy growth. You can see the stalk and it shoots like round single finger leafs almost like when I’ve reveg’d a plant/clone before.

i also get the odd leaf here and there that fold up like a canoe boat. The first time it did it the first thing I assumed was heat/light stress so made sure my 600w hps Stayed at least 20” of canopy. My temp in summer was high due to heatwave (uk) But never saw temps above 30degrees. But with my light backed to 22/24” and winter temps at 24 lights on & 20 lights of I’m still having same problem.

 

no drastic issue as bud quality and yield is still more than I would ever ask for but just annoys me I can’t get to the bottom of it no matter what I try.

1mx1mx1.8m tent with huge 6” fan and filter which to be fair is overkill because I run veg & flower tents piggy backed through it. So environment is good with temps like I say in good parameters 20-25. Humidity average between 50\60% normally the lower 50’s.

600w hps with dimable ballast which I have tried on 400w and still have same issue. 

Canna a&b, bud candy, big bud and overdrive for flower nutes used as and when advised but at 1/3ish dose according to manufacturers. I keep ec on the low side of around 1.0/1.2ec in flow and try not rise above 1.6/18ec out flow. Hand watered in coco once a day to 5/10% run off. Ph between 5.8-6.5.

all photoperiod strains:

gorilla glue

gelato

haribo skittelz

i know it’s an extremely long post guys ahah sorry I’ve just sat down with a J after work. But sure somebody with more experience will love to get stuck into it and point me right. Pictures attached of the leaf curls and the new growth on top. You can see the new white hairs are a different colour to the Lower growth. Thanks guys.

Foxtailing can happen for a number of reasons mate. I think this is down to the feed though. 

You're feeding EC in around 1.2, but getting 1.6-1.8 on the run off? Is that right?

What exactly are you feeding them right now? Like ML per litre?

First week or two after flipping to 12/12 I feed veg nutes, around 1.5ml a litre of a&b around 1.0 ec until after week two I use big bud and bud candy both at 1ml a litre. Then at around weeks 4/5 I stop the big bud and finish with overdrive at 1ml a litre until flush.

i don’t constantly get 1.6 ec run of just if I see it creep up towards that I normally water a little more run of or slightly lower e.c in flow. That’s what I mean about wanting to set a drip up, Ideally I think I should be watering more frequently but less volume but needs must at minute so just try keep ec down that way? It does seem to be around the week 4/5 point which is when I switch from big bud to overdrive. 

I never thought I was feeding high do you reckon I should try drop it a little lower? I use tap water with a background of 0.4ec which is what canna a&b schedule is based on.

See, I would use bud candy, or big bud, not both at the same time. Wait until you see flowers from, then use big buds for about three weeks, four if its a long flowering plant. 

Then, add the bud candy and drop the big bud. 

Overdrive is best used when the trichomes turn 50/50 clear to cloudy. This is when it will kick start all the terpene and oil productions. 

I think, because you're feeding Big bud and bud candy together, the plant is getting too much of something, and it causes a lock out. Then when you change to overdrive, the excess will stop, the lockout will go away, and the plant will start eating properly again. 

This is why you have the white hairs and foxtails coming i think. 

When i used Advanced nuits, I never used bud candy, i find it taints the final flavour if the bud. Adds a certain sweetness that you can tell is bud candy, ( a friend used to use it ).

Yeah mate that makes sense! To be honest I’ve just run out of the bud candy I bought to try and I think I’ll leave it out next time. I thought it would be okay to use with the big bud because it has no npk. Maybe leave the overdrive out too.

I was thinking about Trying canna’s full range tbh heard good things about their boost but people just complain it’s expensive Because of the fermentation process.

What do you use for bloom if you don’t mind me asking? Heard you say you was using organic bottle nutes at some point how did that work out?

it was ok, but now i use the canna ange with some extras. 

I used to use advanced, sensi a n b, with big bud, and overdrive, with some buddhas tree solar green, and fruit burst. made lovely buds

But i found canna is cheaper, much cheaper, and you get the same results. 

All i use now is canna a n b, with some rhizo. Ill use pk13.14 throughout flower. some vitalink calmag, and some buddhas tree solar green. That's about it. 

I find using the same range makes shit easy, but there are some products that are too good to not use lol

big bud is one i miss tbf, and might bring it back for the jacks. maybe some of that fruit burst too hmmmmm lol. 

Many options mate, experiment, have fun with it, find out what works well for you

Yeah it’s got to be better more times than not using the same range hasn’t it. Think that’s what I’ll do next, might even run a full tent of same cut now I’m used to it, but split test half big bud/overdrive and other half pk13/14. You ever used canna’s boost? My pal swears by it and his bud is always 10/10. But like I keep telling him he’s never not used it ? so he can’t really say much at all cos he has no comparison lol.

also yeah I’ve seen your new grow diary mate I’m really exited to watch it unfold ?? Feel like I can learn a lot from some of the diaries on here and look forward to hopefully starting my own on the next run with my new invisible sun led and autos as it will be my first auto grow and first LED grow ?
