Unidentified problem on Mystery plant!

[Waira]

not enough time has passed, and the dosing my not be enough on the PK side, as in how much of those ppm's are from the PK,... base nutes are very mild,...
Don't remove leaves unless there's a good reason, they are mobile nute reserves, and PK are both mobile,...this can make matters worse, not better!
Dry-out are bad news across the board,.. keep moisture levels more even....

 

[Haze4dayz]

The levels are sorted now with the dry outs, have been for quite a while. You say base nutes may not be enough, even so at 4ml per litre? That's the high end of recommended for photos and autos are supposed to only have half of the recommended dosage? If base nutes are not enough what am I supposed to use, as Biobizz don't do there own PK booster?

... with auto's, there's a great deal of tolerance variability for nute strength, to say nothing of all the other factors involved like type of nutes (organic/inorganic), frequency of feeds, medium used and it's own properties, amount of run-off with watering/feeding (goes to potential build-ups, especially in coco), plant size/demand, etc.,.... Organic is slower acting too, BTW,.....but the Canna PK is synthetic I believe? And in forms readily taken up,... So the whole dogma of dilution amounts depends a lot of the nutes sources the selves, NPK#'s,.... It's prudent to ease strength up when feeding, more so with stronger forms though, less so with mild nutes like BioBizz... Using the PK booster can help get the PK amounts up without adding in more N or spiking the total ppm's with other nutes not necessarily wanted,... that, you may want to try a dose or two at half strength first and watch for tip burn,...

Thabks waira. I fed Ph 6.4 water with solely pk booster about 1ml/l last night. Just the one litre of water as I watered them the night before with a low grow high bloom feed, without pk booster. So tonight I will not feed, tomorrow I will flush and re feed with correct nutes ?

I wouldn't advise flushing man! It will most likely make the problem worse. I definitely wouldn't do it unless Waira advises you to

That's why I'm putting it out there before I do it cus I would do something silly like that! Obviously.....

My thought was just incase the levels were off I could flush and replace, but I don't know any of the science behind it.

But I have had to dog sit at the in laws for about 4 days, been a bit harder to be 100% tentative to the plants. Home from this afternoon, 4 days off work due to Spanish fiesta days... Seems to be nearly every week

 

[the green bandit]

If they were mine i'd be upping the bloom a little more and also adding at least 2ml/Ltr of pk13-14 every 2nd watering...i don't think it could do them any harm anyhow

 

[Haze4dayz]

Thanks mate, when you mix up your nutes, do you mix Biobizz and canna pk? It's supposed to damage the microherd right?

 

[the green bandit]

I don't know much about what it does to the micro herd...but I just add it last into my mix along with bloom,grow and cal/mag. I'm looking at swapping it out for an organic pk booster for next round of plants!

I think we're on the same level with that then! I bought the canna one thinking it was organic. Sadly not. But I'm thinking if using up the rest of my Biobizz and switching to biotabs or similar. All I have to do is water and ammend then. So I'll find a better organic pk and also cal mag as well
