First Grow

Hi, Don’t ever just go heavy with nutrients or you might make an irreversible mistake. Less is more otherwise you could ruin your crop. Good rule of thumb is to start with half or quarter strength of the recommended dosage per litre of water. Here’s a schedule chart designed for your brand of nutrients https://www.npktechnology.co.uk/pages/mammoth-p-feed-chart-uk Hope this helps. Feel free to ask any questions. Good luck
