Stickanswered grow question 7 years ago Hi there! You shouldn't be giving nutrients on the first week of the vegetative stage, however your plants look older than 1 week, I'd say they're 15 days old, so you might want to start feeding now. Biobizz has great products, if you're looking for organic fertilizers. They do have some downsides: you can't keep them more than a few months, they tend to smell (in the bottles+in your soil), and they're probably not as much efficient as some other non-organic fertilizers. I'm now testing MegaCrop (powder nutrients), I have to say I think I'll never go back to liquid fertilizers again. Now, about your feeding schedule, I'd recommend not to follow BioBizz schedule, this one is much better : https://www.alchimiaweb.com/images/xl/bio-bizz-bio-bloom_240_2_.jpg. As you can see, for young plants (Veg Week 1 - line 2) you should be giving 2ml RootJuice + 2ml BioGrow + 1ml BioHeaven for 1 litter of water. Hope this helps, keeps us up-to-date so we can help you adjusting your parameters, and happy growing!
