This is my first grow! So many questions

CannaNovice13 · Aug 24, 2021

This plant is 12 days old. Should it be bigger than this?

When should you start using nutrient solution. Cal mag?

Why is my stem purple?

My tent is located upstairs when tends to be the warmer part of the house. My temps usually run from 23 - 27C. Is that too hot for my plants? Humidity at 40%usually

Also my tiny seedling sprouted 2 days ago. Could the heat be causing the leaves to curl downwards?

Describe the media in the cup. How much water. At what PH. So far it's just a bit leggy. Otherwise ok.

I use Fox farms potting soil- ocean forest. I've been using bottled water, and the pH is around 6.0. I watered to run off today. Maybe 100mL

The leaves were growing very uneven at first but they evened out.

Ok good. Then the only move is to move just a few inches closer to the light. If the stem flops over don't let the top rest in the soil. But it should in about a week be much thicker and forming leaves.

For first grow growth is fine...add a little more media around the stem for support.
You can start adding nutrients now..stem purpling comes from the light intensity..its fine.. i get it every grow .temps are good .id stick at around 26-27 .an ir thermometer is what you want to get measure the leaf temps 26-27 is around the mark...
Seedlings might have too much water is why leafs are drooping..

Edit...sorry ..didnt see what media your in so what GNick55 said...

looks perfect, leave the light where it is.
no nutrients yet, your good for a while in that soil. you shouldn’t be using ph up/down in that soil unless it’s an organic stabilizer, synthetic will throw off your ph buffers in the soil.. your watering practices look good for now..

How will I know if the light it too close?
I moved the light a few inches closer a few days ago. Initially, it was 25in from the canopy.

GNick55 · Aug 24, 2021

agree with @Madmax to fill cup up with soil as more roots will grow off the stem..

GNick55 · Aug 24, 2021

praying leaves are a sign that the light is just a bit close (kinda riding the limit)..

Madmax · Aug 24, 2021

Yeah you will see edges of leaves turn upwards.mine are right now ☺im a little close foe day 4 at 20k lux ..its funny you can have too much intensity on seedlings but the damn things will still stretch hence why my light is a little close..

So the leaves purpling because the light intensity is too high. Should I dim the lights a little?

Only move it like 4 inches. Small incremental moves.
