Hi I would like some help, I am raising some plants for future mother.

I have problems with a few of them that seem to be growing fastest and strongest.

Hard to understand what yer saying, assuming English isn't your 1st language

 

[zeR0]

Yes its not me first language. ask me what you dont undastand i try to explein and give more information.

 

[Chris Scorpio]

Like Silver said, the look pretty good

Check your fan, be sure it's not beating up yer plants

If it's an all in one soil, not much u can do

What's yer water pH? Is it tap water?
Maybe get Calmag just in case

 

[zeR0]

Fan checked. Yes all in one soil.
Water ph about 6.5-7.
Yes its tap water.
90ppm
19-21 celcijus

 

[Chris Scorpio]

pH is high

Shoot for 6.3

Was fan pointing straight on yer plants?

 

[zeR0]

Yes. Straight to plants. Okey i try to cast with water with 6.3ph ~

 

[Chris Scorpio]

Keep fan off the plants, bounce it off the wall or something

It can tear the leaves like yer seeing

 

[zeR0]

How think? Make run off to look what ph in the soil?

 

[Chris Scorpio]

How think? Make run off to look what ph in the soil?

Huh???

 

[Chris Scorpio]

pH in soil and runnoff don't matter

It's yer water/nutes mix pH that is important
