When should I use nutes?

[dustypropcrop]

Hi there fellow growers,hope you and yours are doing well. I've currently got 3 skunk #1 and 1 special kush plants on the grow. They are only 23 days old,in a small tent,under a 400 watt hps light.I'm using a soil mix which is 75% john innes #2 soil and 25% perlite. This is my 1st grow folks so be gentle,lol. My soil states on the bag there is enough food inside to last 4-5 wks,so I'm wondering if I should wait till after 5 wks or maybe start at week 4 but at half strength. I'm going to be using bio-bizz nutes. Thanks in advance for any pointers guys

I would think in the 4 week at half strength like you thought.

I was having a similar problem of not knowing exactly how much to add, but then I got an automatic hydro system. You have to love technology! Its so cheap these days, it almost doesn't make sense not to use it lol. I cut the time I spend in half.

Nutes in the soil, and time release nutes make it difficult to know when to feed, and how much is already in the soil. Next grow I'd suggest some plain soil, or reuse this soil after adding some organic amendments.

Your plants looks fine for now, I'd hold on with heavy NPK fertilizing and maybe focus on getting microelements in balance instead.
