help needed with nutrients

ok im getting all my gear ready for my first hydro grow and i need some tips/help with nutrients

i have some black majic mega grow im gonna use and apart from some ph up and down is there anything else i should be adding with the water?

also i read that i should start with a ppm of 200 and work its way up 200 every week untill its 1000ppm, does this sound right?

oh and another thing on ppm, if my water is 100ppm befor i add the nuts, do i allow for that or make the first week actualy 300 ppm

Don't know a thing about BMMG. Is that a 2 part nutrient (grow and bloom with the appropriate micro nutrients? I use General Hydroponics Flora series nutes. It's 3 parts - seperate grow, micro and bloom with good success. It comes complete with a feeding chart and here's a chart you can customize by week

Yes you subtract your 100 ppm water from the total your EC/TDS meter give you as in first week target 200 + 100 water ppm- 300 new ppm target. As far as nutes go in hydro. I give water only until I see the second set of true leaves (the leaves it uses to crack the seed don't count.

The GH flora is all you will need until the bloom phase. I then add Liquid Karma, CannaZyme and a little Super Thrive to increase the yield but new growers are best to stay with the basics and learn as they grow.

I second everything MostlyCrazy said. I use the GH products also.

hey fellas sorry for the late reply

thanks a lot MostlyCrazy for you advice

year bmmg is a two part thingee and has all the micro tuff needed

how often should i chang the water? every two weeks or once the ph gets to low? is there anything else to worrie about other than ph and ppm?

I change my res weekly or at least every 10 days. You never know exactly what nutes are being taken as a vegging plant will take more N while a flowering plant will take more P and K and you need to hit the reset button every once in awhile to square things up.

When you do the res change check your roots. They should be white and smell like lettuce. Also check the feeder tubes for proper flow, your air/air stones and water pump for proper function and I reseat all my electrical connection or at least make sure the are solid in the outlet.AKA - Make sure the shit is working right! LOL! I also clean up the grow area as best I can and get any dead leaaves off the plant. When they die I have a 20 oz soda cup close to the res. I save all leaves for oil later.

great idears mate! ill be on my way to making the best smoke in the southern hemisphear soon!

OK, you handle the south and I'll do the north! LOL!
