lockout? k def? Help!

So got back into growing here after a 6+ year break and this is my first run back. Previously I ran GO in roots organic and had pretty good success. I took a different approach this time and needless to say it's not going well.

First let me layout my environment & setup..

77*
(68* at night )
60-65% humidity
(6) 600W metal halides (20x8 room)
Very good air movement
20/4 light cycle
Promix soil

Nutrients
AN Connie A+B
Seniszym
B-52
Rhinoskin
Recharge bennies
Botanicare calmag
(Everything at half strength EXCEPT calmag that gets 5ml/gal)
Roughly 900ish ppm (.500 scale)


(Mykos -+azos at transplant)
RO water
PH 6.2 at feedings/watering
Soil PH 5.9-6.1

They get fed on a feed//water//feed//water basis 2-3 quarts each (only the bigger healthier ones get 3 quArts) every 3-4 days

They are in 15 gal smart pots.

I have a feeling over watering will be a lot of the proposals but I am letting them get dry between each water, just not enough too let them wilt

To me the edges of the leafs look like a potassium defiency? It has to be more then that, atleast that's my thought?

Pics failed. Try again?

Kdef where yo foto?

I just hang around to learn..

Use the direct URL .Edit out the [/IMG] tag or put a space or something

Am I on the right path here? My only question is how could AN conn Grow A + B plus my supps be so incomplete that I'm getting a K def? My PH seems to be right in the sweet spot for soilless so I can't be locking it out?

Should be fixed. Sorry about that

from the bottom up... bro I'm thinking m
nute burn. have you upped your nutes recently?

the leaf edges look like K problems, but the curl looks like you may have root problems, which could be causing your K problems. you're already running benes, maybe get something like hydroguard and dose it good, can't hurt to try

Looks like you water way too often for that size pot/plant. IMO. According to your schedule up there. I saw bigger plants in 3g pots get water every 3-4 days and fold under.

AN wants to sell you more bottles... I would add some liquid kelp if it were me. get a EC/PPM read on the nute drop. Sorry just saw it 900 is 1.8 EC kinda hot for veg.

When that sheet runs out. Take 10$ and buy a kilo of maxibloom and use at 7gr per gallon plus 5ml of ca:mg per, in veg and bloom and ride off into the sunset..

yeah you upped your nutes thinking more is better....no no no. that's nute burn all day!

I am thinking it has some burn as well after seeing the EC. IMO of course. Have no clue about the strain.

This is Girl Scout cookie, sorry forgot too mention that.

If this is nute burn, should I attempt to flush even tho I have them in such large containers? (I went from 1 gals too 15s)

Also, reducing my nute strength too 1/4 strength seems really weak for plants this size in promix?

I have a different strain in 1 gals that are 3 weeks from seed and are thriving on 1/4 strength (600 ppm)


Root rot seems the most obvious too me at this point bc they are drinking water VERY slowly and the leafs are becoming dry and frail

coukd adding in other bennies like hydro guard recover them or should I stop wasting my time/effort on these?

I really don't wanna scrap these n start over but they're 5 weeks old at this point n growing extremely slow.

ahh you re-potted to ALOT more soil...soil have nutes in it? and you added nutes... I'm thinking good old flush and wait to see what happens..in my opinion

yeah your smaller ones used up all the nutes in the soil so they need outside help. you didn't account for that with the up-potting.....why I use coco, their destiny is in my hands ha ha ha...sorry off track. flush you'll be ok.

i'd try some hydroguard, but thats up to you

I'm using promix, it's a peat based soiless with nothing in it besides a little myco.

I'm gonna give that a shot without flushing, I'm very scared too contribute more too flooding the root ball n suffocating my plant ATM .

If anyone disagrees with my train of thought let me now.
