ph, ppm, lighting etc for new seedlings

hey guys

this is me first time hydro with pot, i have grown tomato's hydro though

im using rock wool sitting on top of hydroton, under 24h fluro lights at the mo, DWC, water temp 68f, ph between 5.8 and 6 and my seeds have just popped open and i got some little baby leaves.

does everything sound sweet as so far?

questions are...

1) when can i add some nuts (black magic mega bloom)

2) and at what strength ppm or ec

3)do you recomend ppm or ec and why

4) and when can i shift under my 400w hps lighting

thanks for any input

dont feed for another 3 weeks or so...ppm and Ec are the same thing. change lighting in 3-4 weeks

Seedlings, Early Sprouts 100 to 250

Early Vegging 300 to 400

Full Vegetation 450 to 700

Early Blooming 750 to 950

Full Mature Blooms 1000 to 1600

You can put your seedling under the 400 whenever just start it high and lower little by little

Hi Lion


Before you go any further with nutes....may I recommend a program?

Have you heard of Lucas Formula?

It's a very tried,tested and true Nute system that is inexpensive and effective (in the opinion of many).

It will give you direction with a good MJ nutritionial system from A to Z.

I have never heard of Black Magic, but I am no expert. But I do know that MJ has a unique nute requirement and Lucas Formula is tailored to it. Eventually you can tweek and add to it, but it's nice because it's very comprehensive.
