DWC - 3 días - plántela amarilla?
Frm11001started grow question 5y ago
Hey! It's my first time in DWC and rock wool, my seedling has been growing there for 3 days and I see it a bit yellow, I think my rock wool has been wet for a long time, could that be it? I have another seedling in the same conditions and it looks good!
What do you suggest?

Your ph should be at 5.5 to 6.0 with 5.8 being best for veg. Your nutrients should be at 400 ppm 0.8ec if it is a photo period and 200 ppm to start if it's a auto. Increase by 100 ppm 0.2 sec every week if your seeing good growth stop at 800ppm 1.6 ec for photos and 600ppm for autos. Keep your water cool and lots of air with the levels just touching the rock wool, or just a touch below.

Test your pH, that's the first thing. Next, make sure the light is not too close, I typically put my 100W about 12" from sprouts/seedlings. Its not a deficiency yet, I can promise you that.

Is this a root or the upper part of the plant ?I made the germination in a rockwell cube, nothing happened on the top, but hopefully something is growing on the botton.
Is this a root or the upper part of the plant ?
And it's normal to see the root before the plant ?

My 1st clones1st attempt at clones. Phd to 5.8. Cut at 45 and slightly skinned the bottom 1/4”. Sitting on heating pad with timer 15 min on/off and 4 T5s on and humidity vents closed
Most fell over, I believe because it was too moist and warm
Will they make it?

Very slow start. Do I have to be patient or is there something wrong?Hi guys, it's very slow. Parameters seems fine.
The EC goes up to 1.2 in 48h. Out 3 liters in the deposit, put water ph7&EC0.05, corrections to Ec 1,0 and pH 5.5.
I'll do that daily.
There is a top 6L deposit with still the "old" Ec/pH and mix slowly watering.
Any tips please

Seedling tore its cotyledon off while sproutingOne of my seedlings tore one of its cotyledon off emerging from the rockwool cube. It left the leaf and half of its seed shell in the cube. Is this common or did I make a mistake planting it in the cube? Maybe too tight or too deep?
