When to transfer to bigger pots?

Hey guys,

I have a couple plants started. First one sprouted about 13 days ago and the second probably 10 days ago.
I'm pretty sure i can see some small thin roots through the bottoms of both cups. Does this serve as an indication that they're ready for transfer?

Here's pics from today:

Cheers!
 
as soon as you start seeing roots on the sides of the cups they have out grown the cup. I would wait a week or so . those are to brittle to repot. if you drop one on its side or so your in trouble . keep in mind people grow plants in those cups a foot tall. so no rush. unless you in a major rush for money then repot them now and shoot as much juice as possible onto them. my luck 1 would tip and break the stem .
 
im am going to suggest hitting them with 1/4 strength nutrients . seeing some yellowing and dyeing leaves. don't go full strength. 1/4 strength max 1 light watering .
 
i wouldnt re pot them just yet there to small and the roots to fradgile, dont feed hem anything yet one of them has nutes burn

kindduesel why would you wanna feed a seedling this young? the soil on its own will support a plant for upto 1 or 2 month depending on the contence

The color of the plants is very yellow. I think that's where he was coming from is saying to feed.

OP- does have problems, I see pic (3) leave tips curling up, some twisting, and leaf edges curling up.
 
Im going to throw my 2 cents in. First I never transfer my seedlings untill they have rooted out the bottom fairly heavy. More roots the more likely they will take to the new pots.

As for the discoloration, ive never nutted anything that small so if you did I would be super careful. Im no expert but whats your temps at? Might be to hot, or not enough air movement..
 
Temp fluctuates between 73-90 depending on if I'm working or not. I have them in the room I work in and the fan gets too loud sometimes so I have to shut it off (causes the temp to reach 90 sometimes). I have not given them any nutrients yet. In fact, I don't really plan on giving them any. I have a super soil mix cooking right now that I plan to transfer to. The only sort of nutes I bought were great white and bud candy, because I heard good things about both. But I won't be using either one of them for quite a while i think
 
Is there any definitive way to tell if the leaf damage is due to nutrients or light/heat? The new leaves look really green and healthy, but they seem to slowly change yellow then brown...
 
The 90 degree heat isn't so good for them. Try if you can to keep it at optimal 76 degrees and no more than 85 ish is best. What's your base soil ? Maybe its too hot for seedlings or its run out of nutes but running out this early isnt likely. Reporting them will help them grow. Once you see roots I leave them a week. Just becareful of your root ball. I usually wait till they need water. Helps slide them out of the cups and you need to water when you transplant so its a win win. You might want to get red solo cups to double cup your clear cups. You can still slide the cups out of the red ones to check roots and you won't have any light on the roots causeing you issues. Your water if its city water could have chlorine in it and if its well water the ph May be all whacked. It's a learning curve good luck.
 
All your leaves but a few lower ones should all be a nice darkish green . A healthy green. Old leaves fall off it happens. The super soil should do you wonderful.
 
I ordered a little pH tester from amazon for $13 today. Ive been using a combination of 25% RO / 75% tap water, and I have no clue what the pH is... just trying to get the best of both worlds I guess...I am using fox farms light warrior as starting soil.
 
Does anyone recommend a nice cheap humidifier? I live in arizona so i'm pretty sure I'm going to need one. They look pretty expensive though and most have bad reviews lol. I know I'm getting a little off-topic here but I've gotten great replies on this thread for some reason lol...
 
I dunno. I've probably watered them 5-6 times. I weigh the cups with my hands and wait for the topsoil to become night and day difference (dry and wet).
 
I think it's rare that they are getting to 90 degrees. you can barely see the edge of my thermometer / humidity reader in one of the pics. It reads between 76-82 degrees 90% of the time at least.
 
IMO- You might have given them to much water. The soil might be to compact. Not letting air in. Temperatures, Humidity are prob. messing with your seedling.
Your plant uses Transpiration to suck up nutrients/water from the roots. As Humidity rises the Transpiration process slows down.
Like a Hot Humid day for people you can't cool down because it's to Humid for evaporation to take place.
This is similar with your plant, the water can't evaporate from the stomata of the leaf.

Good air flow would be my first attempt to lower humidity.
a nice big cheap fan blowing on your seedling.
Don't forget "Little Plants Need Little Attention"
Don't over water or over Love them. You'll kill them.

Good Luck on Your Grow.
 
I have a huge AC blowing 6 feet from the seedlings MOST of the day/night + a small little PC fan directly on them. It's not too much. They barely move in the wind. But I really doubt overwatering is the issue. I think it could be heat, it could be water pH, and it could be nutrient burn, i would just like to isolate the issue..
