hey guys, help me navagate aquaponic budding deficiencies!

[puggle6]

hey guys, got my aquaponics system rocking bad ass and always on the improve.

seems the finishing is the difficult part, halfway through budding plant looks like it's dying /eating itself.

I have 2 autos in my tent flowering, they look like they both have a tiny bit on N toxisity, the older plant (LSD-25 on the right is slowing bud production and yellowing, my test grow this also happened but there was a lot of stress for that test plant.

the younger plant (girl scout cookies) is doing great apart from a bit on N tox I guess.

light is 600w hps 24/0
nutes are fish water (readings are good from my freshwater master kit) these are veg nutes and base flowering nutes
ph 6 ish
added nutes are GH BioSevia Bloom

both are dwc but the GSC is on recirc with the fish tank, LSD in own pot, have been concentrating on blooming her while GSC gets a hand feed of BioSecua (which is 2-3-4)


anything locked out?, Cal Mag? Iron?


thanks in advance

GSC above

LSD-25 ^^


should I do any trimming on LSD-25 to expose the main producing branches?

What's your humidity because I have the same problem and I believe it's because my humidity stay so long it's hard for me to get it above 40

And if it's an auto you should do no trimming ever cuz you don't want to put any stress under them or else it's just a loss of a week of growth or two

And the spots look like cal-mag possibly deficiency what are you using for that

heya, yeah humidy ranges 30-60!

I thought Cal mag, I am limeted how I use ANY nutws as fish may die! However they are hardy

have only used fish nutes for veg, never a problem

only in mid bloom a fast finish and no bulk, all reading good

[puggle6]

have checked and all looks good for feed, maybe
lockout?

I have something like 100ppm of nitrate in my water, fully converted (ammonia & nitrie)

ph 6
EC
(not relevant to me but should be 800-1000ppm so they say)

meh

LSD is like day 44, I guess she could be finishing herself?

the GSC is booming, not stretching but little bud formation :/

Posting issues in the infirmary will get more notice. I hope they regain health quickly! @Waira

Hey, nice grow, I always been intrigued by aquaponics.
The rust spots clearly look like calcium deficiency to me. The light green leaves I'm not quite sure as it looks like nitrogen deff but you also have signs of nitrogen excess, might be the beginning of a magnesium or iron deff but I'm really not sure.
To fix your problems without affecting the fishes, you could try a foliar feeding (1/4 dose of calmag and maybe humic/fulvic acid). Try to not spray the buds, target the fan leaves (upper and under side) with a fine mist spray.

I use optic foliar as a leaf spray, totaly sold on it but the aquaponics water still lacking.

for bloom I use BioSevia however it might not have all the feed for the plant.

aquaponics perfect for veg, trying to solve the bloom!
