Nutrient questions

first time hydro grower and not sure what to believe. I have Advanced Nutrietns GROW MICRO BLOOM, and their website has a nutrient calculator, but i hear marijuana can be sensitive, and I should use only half or quarter strength when mixing. Can anyone help me out?

Try it at your diluted strength. Worst case you'll get slow growth. Increase each week until you feel that your plants are getting what they need. I'd suggest taking notes and taking pics for your own personal research. You want those data points from each week in order to really get a nice schedule for your strain. But it's safe to say that starting at half strength is a good starting point.

Thanks man i appriciate the advice. Ill start with half stregnth and work my way up from there, i figure by week 5 or 6 it should be stronge enough for a full strength solution. They are just really good bag seeds, so its not like im wasting a good strain experamenting. Thanks again man.

I have one more question, how many times a day should my plants eat? Ive heard 3 times, 4, I ve heard as much as you want but only in the daytime....and plenty more bullshit. Advice..anyone?

It depends on your medium. What are you using?

Im using rockwool and expanded clay pellets

I use AN at full strength with no problems and great results.

Homebrewer was right in everything he said. What you will start noticing after each grow and growing different strains is how each plant reacts to feeding. Some are heavy eaters and some will be light eaters. So that's why it's always best to start at half or even quarter strength. I've had plants that couldn't take anymore than 1.2 EC and some that can take all the way to 2.2 EC.

Btw, I also use AN 3 part nutes for hydro. I have never been able to feed at full strength. I use a bunch of other nutes too so I can't get my 3 part too high or my plants will burn.
