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.

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?

My Cherry Grapefruit has developed a decently sized tap root but it's taking her FOREVER to break through the root cube. Do you guy's think I should give up on her? She's already a week behind my other 3 plants and I'm already limited by a pretty small grow space. Thanks!4 years ago

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 ?
Thx

Where to put top feed line during germination?Where do you guys set your top feed line on rockwool cubes during early germination? I do not want to overwater them and drown them out but at the same time keeping them damp.

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
