Weak plants

[Tentacles]

Ei everyone. It's my first solo grow. I use a 300 watt niello=300 watt viparspectra for 2 plants with cellmax universal soil for now. They have 16 days old. For me they're to weak and bent. Is the light? The other is small and almost fall to the ground. Thx
Humidity 50-60
Degrees 24-27
Ec 1.5
9 l pots

Dont know anything about that soil, but 1.5ec is high for plants that size. Not an LED guy either so nothing to add there..

 

[Tentacles]

Yeah I know it's a little strong for young plants.. I hope they grow decently :')

Use a small oscillating fan, direct the airflow over the tops of the plants so it makes them move a little but not too strong. Run for 12 hrs a day on 12 off, will help build stronger plants.

And welcome to the farm!

Take it or leave it this my own take on my experience.

I start with 600 ppm week 1
1200 ppm week 2
1200 week 3
If you go over 3 weeks veg
1500 ppm week 4
1800 ppm week 5 and hold there
At bloom I flush and go to 1000 ppm week 1
1300 ppm week 2
1600 ppm week 3
1900 ppm week 4
Flush weekly
hold there until last 2 weeks and add your bloom enhancers if you use them.
Good luck my friend.

.5 or .7 scale on your meter?

My TDS meter reads in ppm.. If i'm not mistaking 1500 PPM would be 1.5 ec

I am wrong on the conversion. It should be
To get an EC value, multiply the ppm reading by 2 and divide by 1000. Thus, if your EC is 1: 1*1000/2= 500 ppm.

 

[Dirtbag]

Right. 1500 would be 3 ec and 1900 is almost 4 ec on the .5 scale. A little over 2ec and almost 3 on the .7 scale. Some meters can read both .5 or .7.

Wow those are high numbers. Ever try lowering them and not flushing every week?
