Nutrient burn?

[Fantomlimb]

I seem to be having what I think is nutrient burn but I have no idea. My EC is 1.7, im on the 10th week of grow, 9th week of flower. Last Rex change I cut out the flora from nutes. I noticed it a few days ago when I changed the Rez water. It seems to be mostly on the fan leaves. Lower leaves seem not to be effected mostly just the big fan leaves. Any idea what it might be?

Nute burn typically affects the leaf tips but you’ve got burnt edges too, I'm a soil grower and have never used flora so I don’t what’s in the product but maybe it’s potassium deficiency?

hopefully more replies will come in soon

I had potassium def and it looked like that. Mine was due to lockout and was corrected with a flush. No idea what to do in hydro.

Still early so don’t make any rash decisions until the more experienced show up.

Flora Series is
Flora Micro 5-0-1 with trace micro nutrients
Flora Gro 2-1-6 with magnesium
Flora Bloom is 0-5-4 with magnesium and sulfur
I also use Calimagic which is 1-0-0 with calcium, magnesium and iron

I’ve been using this schedule

Lol you seem to be on the same track as 013 so maybe it is potassium, hopefully these experts show up soon lol

Ok to be clear and set you up for the others - you said you cut the flora, did you cut all of the nutes and just do the cal-mag in your rez?

 

[Fantomlimb]

No I cut the Flora Gro out and was using micro and bloom and Calimagic only as per the schedule I posted.

 

[Fantomlimb]

However this happened during the last week before I stopped using Flora Gro when I halved the amount of flora Gro I was giving it. This week I completed eliminated it.

Maybe it is/was too much N, think I would have cut the micro.... good thing you stopped them all perhaps..... but hey I can’t even spell hydro...!

its all good, someone will stop in

I think there is still some confusion. I only cut out the Flora Gro, not the Flora Micro or Flora Bloom or calimagic

 

[013]

Right but in veg you want Higher N and lower PK but opposite for flower right?

you cut the flora gro 2-1-6 which has less N
I would have cut the flora micro 5-0-1 which has more N

because in flower you want less N & higher PK

anyway it doesn’t matter now!

Honestly I just go by what I’ve read. This is my first grow ever. For the flora series it seems that most things say to cut out the Gro towards the end of flowering. I’ve even seen a nute solution on here where people only use Micro and Bloom without Gro the whole time. I think it’s called the Lucas method.

I believe GH schedule for early flower is 4,1,6 and for late flower 4,0,8 ml per gallon of Micro, Gro, Bloom.

Why no micro and the extra FF Bloom?

edging with tip burn is a sign of potassium def. it's hit the wall in flower and is consuming the added pk it needs to flower internally.

a small bump in feed could probably help. it doesn't need the n. issue is not that bad now but will progress. a lot of grows just let it happen, some adjust. it does happen "normal" to a degree. if you use a pk booster now is the time to start.

Bluter for the win!

Like I said, I’m following that schedule I posted which seems in line with others I have seen. I’m not sure where this idea of no micro is coming from. I use 1 tsp per gallon of Micro, 3 tsp per gallon of Bloom. Or 5ml of micro per gallon and 15 ml of bloom per gallon and again, that’s because of the schedule I posted. Is that too much bloom?

The only things I use are the flora series, Calimagic, and Hydroguard. If I were to bump up feed, how much.

Like I said I’m currently using 1tsp of Micro, 3 tsp of Bloom, 1tsp of Calimagic, and 2ml of hydroguard per gallon. Using Zero Water filtered water. EC of 1.8

My bad. I misread. :/ At this point it is above my knowledge. Sorry.

Ok that Lucas method is from 2007 and may not account from changes in formulation over the years plus you are out there pretty far in hydro land beyond my abilities. Shout out to @bluter

 

[Fantomlimb]

I’m not using the Lucas method, it was just an example of how I thought “gro” wasn’t even really needed. I’m using that chart up above that was updated in September. But I thank all of you for your input. Hopefully @bluter will comeback with super sweet knowledge soon
