You will have good bud starting out slow with the nuts. I would start with 1/2 of the suggested for the 5th week. If you think you are burnning them, pour 1/3 to 1/2 of your tank out and fill with water. This will dilute it and prevent you from having to waste nuts. Remember, if you are using a medium that absorbs liquid, the medium will release some of the built up nuts and raise the level even after adding water. Unless you are going to flush them?? Your water with the nuts should be a nice amber to light orange color. Time to add water is dependent on how much the plant is taking in. Check your tank and make sure you are keeping the level up. I change my tank once a week. While it's empty, I wipe down with a towel to remove any nut build up. The plants will do well without overpowering the nuts. I used 1/2 strength of all my nuts until I got the hang of mixing. Also, are you adding your Micro first?? If you are using any bloom boosters that should be first, then micro before anything else.
