Killing Autoflowers and Learning to Grow Organically :p

[ajgrows]

Day 7:

RH 50% temp 76. Increased wattage to 55%. Raised light 2", another 1 oz of water ph 6.5.

 

[ajgrows]

Grabbed the Photone app and checked PAR readings because I really have no idea if I'm giving the seedling too little/too much light. At 55% power on the TSW2000, it reads right around 250, which is good. I will gradually increase this up to 400 µmols as the seedling grows. I realize this is probably nowhere near the accuracy of an expensive PAR meter but for $6 it keeps me in the ballpark and allows me to have another environmental metric to test

Day 8:

Looking good, 2nd set of true leaves are visible. Still feels like it's stretching so I kicked the light up another 25 µmols.

WATTS	60%
PAR	275
LIGHT DISTANCE	24"
RH	53%
WATER	1 oz
PH	6.5

Day 9:

Quarter turn of the pot, turned up the watts another 5ish %, raised light to maintain 24" distance.

WATTS	65%​
PAR	310​
LIGHT DISTANCE	24"
RH	49%​
WATER	couple oz​
PH	6.5​

Flood it. Make sure the entire pot is wet. Then let it alone until it's almost totally dry.
An ounce. OMG.

Watering for Soil Growers Only

Watering in Soil Watering plants gives many new growers anxiety issues. Because we want our plants to do the best they can, we over water and some even underwater. To help relieve the stress and confusion, this is sort of a step by step of what to do and look for when you grow in soil...

I did give it a heavy watering last night after your post. That’s what I did in my last grow at day 7 and all three looked just like this one within a day of doing so, then died. I assumed it was overwatering that caused it. If it’s the opposite I’d actually feel better about the negligence.

How do you water your plants in the first weeks of growth?

Just exactly the way it's written. We keep our plants on the edge, pushing for more growth.
Lets see some fresh pix.

You're showing nutes being fed on day 1. Ffhf soil needs nothing but water for 1st 3-4 weeks.

Dry amendments at 25% dosing. Doubtful it's even broken down and available to the plant in the first several weeks.

Gotcha. So soak the whole pot even as a seedling? I can't find much online that look like this poor girl does today. Browning from stem outward on the leaf. If it's damping off, I have no idea how I'm introducing disease into the soil.

From your first picture (of the limp plant) I would have said water. But if that was the case the plant would just shrivel up (like a pulled weed). Yours has the weird tan coloring on the leaves, which is something else (and I’d suspect lighting. But not an indoor grower myself.)

And yeah a seeding needs to be keep constantly moist, no dry out for the first week or so until it’s established. But no need for a humidity style dome for seeds. Give them fresh air with moist soil.

 

[ComfortablyNumb]

That has the marks of overfeeding.
What amendment did you add?

What lights do you have and how far from the plant?
If it has a dimmer, what is it set on?

Pretty small amount of amendments:
3 tbsp Down to Earth All Purpose
2 tbsp DTE Bloom

I did mix in about 10% FF Ocean Forest that I had leftover from the last debacle. I have no reference, but assumed that wouldn't be too hot to start them in.

Mars Hydro TSW2000; 300w max. I started it at 50% have increased to 65%, which was roughly only 250-275 PAR at 24". From the research I've done, I don't believe that is too much.

I'm thinking just straight HF with no amendments and more water for the next one.

I like the FFHF for seedlings, it holds water better than the Ocean Forrest in the small pots. I don’t do autos, so normally up pot from a solo of HF into the 1g nursery (really .7g) of FFOF, but won’t feed a seedling until about 2-3 weeks (around the 3rd set of leaves or when the Cotyledons start yellowing). If you start in a big pot, just build a little center spot of the HF about the size of the 1g pots.

As a 1st time grower, i used ffhf soil. No added nutes at first. No issues.

Ok, moving on to ROUND 3 of trying to keep a plant alive for more than a week

Mendel's Mystery Mix Auto​

I hate wasting things. Soooo, I dug up the round two contestant just to see what was going on below the surface and I am going to reuse the medium since it's still rather fresh. For only 6-7 days of growth I am really surprised at how long the roots are!

The soil was wet all the way down to the bottom of the roots in about a 2" diameter around it. This leads me to think maybe I was watering too frequently, even though I was administering small amounts of water. Maybe I'm an idiot. I'll just keep trying to prove that last statement wrong

I snagged a freebie 4x4 tent for review purposes, so I figured I'd make this 5 gal pot look tiny in the completely oversized tent for a single plant. My new ducting was supposed to be delivered today so the inline fan is hanging in pieces until tomorrow.

Found a little friend snooping around in the tent, I figure it can stay and eat gnats and $hit.

DTE 4-6-2 ALL PURPOSE	3 tbsp
DTE 4-8-4 BLOOM	2 tbsp
WORM CASTINGS	2 lbs
HAPPY FROG SOIL	1/2 bag
5 GAL POTS	1
WATER	1/2 oz
PH	6.5
WATTS	50%
PAR	250
LIGHT DISTANCE	24"
TEMP	72°
RH	52%

 

[ComfortablyNumb]

Feed it nothing but water for the first two weeks at least, probably 3.
Replant it. It's not dead yet.

It's mixed up somewhere in the reused medium now.

As a black thumb plant killer myself I had same issues with damping off. Frankster and the good guys here with the articles in watering set me straight. Im currently a few weeks into my 1st successful grow. I soaked the entire pot a day prior to planting. Next day I dropped the seed in with some plastic wrap on top to keep humidity up until they popped. I went 15 days before the pot was dry and light. At that point the plants had about 2-3 set of leaves, were healthy and green, and weren’t stretching. Right after that first water is when they absolutely exploded. That first seed to a dry out and then wet cycle really made all the difference in the world. I actually have a bit of confidence going into flower with some healthy plants now! But the wet/dry cycle is no joke.
