New Grower First Grow : Short Stuff Onyx, CFL, Rubbermaid

Are they really small compared to other similar aged autos?

I have been thinking about this for a few days. Didn't ask because I thought I was being a nervous nelly. After looking at photos and journals of other autos my plants looks small compared to others of the same age. My two Onyx are 8 days old in the last photo I posted on the 21st. So is it all in my head?

They do seem a bit small, but they should take off real soon, wouldn't worry to much :smokebuds:

If your temps and humidity are holding at what you posted earlier, then the only things I can question would be watering and the growing medium (or a combination of the two). With little plants like this it's pretty much always better to err on the side of letting them get too dry rather than too wet. I think seedlings thrive when they have to search for water with the roots. I haven't used your seedling mix, but with Light Warrior I only water my young plants about once every 4-5 days. That's giving the soil a full water until I get runoff. But in between things should get good and crusty for the top few inches of the soil.

You've also got soil with time release nutes, so if they're getting a bit too much water then the problem is being compounded by the release of more nutes that the plant can't use. That's why most stay away from the MG soils, though we do have members who use them for successful grows.

More pics would be helpful. Good vibes sent your way & I have no doubt we can get these girls kick started.

Maybe it was because the 2 lights were 1/2 inch away from them. I thought they were farther away. They are now 2" away. I had to cut a small, coverable peephole plant level so I could see the distance between the two. The lights were on 24/7 for seven days until I realized I should have changed it to 20/4 a long time ago.

Stupidly, I didn't realize the MG organic garden soil had any time-released fertilizer in it. I thought I had read a lot about it too. I know the Potting Soil had time release ferts in it. That combined with a small amount in the MG perlite and the organic seed starter. I wonder if that is the culprit. Soil was the hardest thing for me to find. There is nothing in any of the local box stores that isn't loaded with ferts. The local nurseries don't carry anything. One carried Bacto or something. I couldn't find much info on that brand soil though. Driving to a hydro store is a hour + drive. Not something really feasible for me either is making my own soil mix.

I have been watering once the top 1-2 inches is 100% dry. However, below 2 inches they were slightly wet. I haven't been drowning them though. I am watering every other day. Sometimes every two days.

Here are a ton of photos taken just now. Not very good photos. Day Ten. They have small spots on ridges probably burn marks?

They all cracked on the 12th, planted them into the 3.8 gallon (12 inch diameter) pots. Sprouted above soil on the 14th. I just watered until runoff yesterday. I think I am going to need the soil switched.

Onyx # 2

Through peephole showes light distance to plant.







Onyx # 1






It would be easier for me to drive to a hydro store than mixing my own soil. Is it too late to transplant?

Right now temp is 77*F
Humidity is 58%

Temp and humidity are good, my guess is they were hot from being close to the light.

I use ferted soil and have no problems, different brand though,

I can see where I think there is burn from the lights, on the pointy ends of the leaves. However, the new set of leaves coming in almost looks to have yellow tips. Especially in Onyx #1 where the leaves are more developed. To me it looks like nute burn, however, I have no experience diagnosing this whatsoever.

I will start watering them less too.


I am thinking of switching to Roots Organic Soil......

I wouldn't transplant right now. The less you transplant the better -- every time you transplant you risk stunting them and your yield as well... Some people say MG is great for growing pot. I for one had a very bad experience with it during my first photo grow but in retrospect I was over watering and doing that with what MG is made from will compound your problems. I would suggest the same... Let them dry out a bit but not totally. You do want some moisture there so they keep seeking for it but don't overdo it. CFL's can get very hot up close, especially for seedlings. I think with a few minor light adjustments you'll be fine.

Don't stress too much on the size of your plants. I was stressing out about the same thing on my first auto grow of Snow Ryder... Every grower will take some time getting dialed in and that's absolutely fine and natural. They will start to take off soon trust us. I personally don't see a HUGE burst in growth until bout 2-3 weeks in... That's when they start almost doubling in size every day for a while there -- for me at this point anyway. You will see it soon!!

i had a greenhouse seed the church (fem) that turned into a 6' male last summer that was grown in mg soil as
this place http://www.plantlightinghydroponics.com/grow-media-c-79.html has the roots organic soil for $9 and change was thinkin of getting some but ended up going with ffof instead

Okay, thanks a bunch! I will not transplant then. My next grow I think I will be using something better from a hydro shop. I will just keep a close eye on the plants, watch overwatering, and monitor light height.

I need to pick up a light timer this weekend as I am tired of turning lights off and on manually!
