What you can learnA strong failure analysis showing nutrient ratios, restart attempts, solution changes, cultivar differences, and a clear termination decision.

Actions:2 Nutrients2 Pruning2 Equipment1 Planting1 Solution1 Finished
Useful practices
  • testing nutrient formulations
  • flushing and switching back to AeroGarden nutrients
  • restarting failed plants
  • separating a sensitive variety for future trials
Problems encountered
  • leaf curl
  • suspected overfeeding
  • high nutrient sensitivity
  • poor recovery after solution change

*The days were calculated automatically and approximately.

FinishedCut down and ended the failing Extreme Bush plant.

Terminated. I killed this ugly thing tonight. I couldn’t stand to look at it anymore. Here’s where it was when I cut it down. I may revisit this when I can give it a tank of its own and really work on how it responds to nutes. For now I’m letting the Golden Harvest have this tank. I’ll move it into my cherry toms post and end this one here.

It looks like nute burn

Sometimes tough love is the best way to go.I had some ugly gardens that I just terminated over the weekend as I don't want my Thanksgiving visitors to see them. And now I'll have some cute babies to show, instead.

I don't disagree but it's still really weird to me. If that's the case that plant has to be pretty sensitive to overfeeding. Someday I will find out!

S
Shawn

Yes, it will be a future project. But I am sure you may have others you want to still try. Always fun trying new things whether they work out or not. The fun is trying and if you have results it makes it better.

I tried planting two of a species called "Better Bush" toms in an Ultra. Kind of a mistake, because one of those plants would have filled the Ultra on its own.Planted easily, grew easily, but only produced two (full sized) tomatoes per plant before my neglect caused their early demise. Very tasty, but in the end, I would have been better off using a Farm Plus (at least) in a more accessible area so I could do a better job of pruning.

This one continues to be interesting. The Extreme Bush plant is very unhappy while the Golden Harvest is growing well. I’m willing to believe it’s nute burn, but if that’s true it’s extremely sensitive. I guess if I really want to figure out the Extreme Bush, I’ll have to start it in its own tank at some point. For the sake of the experiment I’m going to let it keep going until it gives up. Extreme Bush, Day 24 Golden Harvest, Day 24

Hmm, that one tomato is an oddity. But the other looks great.

Extremely interesting disparity. I agree it would be useful to try the Extreme Bush in its own garden with different nutes. Who knows what you could find.

SolutionPerformed a reservoir rinse and refill.
NutrientsAdded 16 ml of AeroGarden nutrients.

N By nick

Here’s this week’s update on these replants. Yesterday the tank got an R&R with a feeding of 16ml of AG nutes. The Extreme Bush plant seems to be doing well, though I am seeing a little leaf curl that I’m wary of. We’ll see.The Golden Harvest plant looks great. It had one iffy leaf as a sprout (visible in the photo), but it doesn’t seem to have hampered it at all.

I dunno, nick...I don;t own a Farm, BUT 16ml seems a very high a dose for such young plants. I wouldn;t be surprised if you saw more leaf curl and signs of mottling down the road. JMO...but, as I said...i don;t own a Farm.

N
nick

16ml is what AG specifies for Farm models on 1st and second feeding. Keep in mind that’s 16ml for two gallons of water. TDS measures between 550 and 625ppm with that dose.

U

yeh. I realize that, and I suppose not owning a Farm I should just stick to suggestions for what I own. But I have burned or weakened a few projects just with the suggested amount over the years and tend to warn others when I see them having trouble. Sorry about that, nick.

S
Shawn

@cornne , i also thought about that. I know with lettuce and some herbs the AT amounts are too strong .

N
nick

For lettuces I’m just feeding 10-12ml every feeding. So, 5-6ml per gallon. They seem to do just fine with that. I could probably even cut it back more but since they’ve all looked so good I probably won’t mess with it. I do appreciate the advice. You all have experience I don’t. I was just assuming following the AG recommendations with their nutes was probably pretty safe. I’ll keep an eye on the toms and see how they respond this week.

I first saw sprouts on these restarts this past Monday. In fact, the Golden Harvest pod had four sprouts. Thinned those out and took the domes off a couple of days later. Here’s where they are today. Extreme BushGolden Harvest

I am eyeballing that Extreme Bush. I so hope this works! I would love to start this indoors for the Spring garden.

The first of the two plants to sprout is exhibiting some leaf curl today. Even with the lights completely lowered they’re a good 5 inches above the plant. It’s around 82 degrees on the deck right now.

How are they doing after the R & R? Happy campers I bet.

Too early for Mooch I thinks. Check the thread in on the Nutes Board.

N
nick

I bet that’s it. Might do R&R’s on all of my bowls with Mooch.

N
nick

Out of an abundance of caution I just did another R&R and switched to AG nutes for this one. I also an an extra gallon of water through the tank in between the rinse and the refill to try to flush it out as much as possible.I’m not confident I’m using the GH nutes correctly so We’ll see if this corrects the curl. Fed with 16ml of AG nutes during the R&R.

N
nick

Neither of these plants looked good this morning so I terminated both. I think they were suffering from the same overfeeding problem as my other plants. I’ll be restarting these with AG nutes today.

M
MaryL

Just out out of curiosity were you able to test the ppm before tossing the water?

N
nick

I wasn't on these but only because I had already done an R&R and switched to AG nutes in an attempt to save them. It was too late though.

M
MaryL

Bummer. Especially after all the excitement and buildup of getting your new units and setting them all up. Well, onward. The future is bright!

NutrientsApplied the first General Hydroponics Flora feeding at a 1:1:1 ratio.

N By nick

This is my first real experimental AeroGardening. Last night I planted two sets of “Extreme Bush” seeds from Victory Seed Company. Extreme Bush is a popular Dwarf Determinant variety that produces 3oz red fruit. Plant height is approximately 24-28 inches. Could be cutting it close, but we’ll see.They were planted in AG sponges and I’ll be feeding them with GH Flora nutes (eventually supplementing with Mooch). First feeding was a 1:1:1 ratio of the GH nutes.

Exciting! A new tom experiment! For the potential height issue, maybe a simple topping will be all it needs.
