10. Feeding - Veg Box



Once you’ve moved into your new 10L grow bags, you’ll let your plants adjust for a day or 2. During this time you’ll give them a Kelpak foliar spray ( see previous post for details ). After this, you’ll go back to regularly feeding and watering. This guide will teach you how to do just that. If you have any questions, pop them in the comments section and we’ll get back to you with answers. We’re here to help.



In this box ( Veg ) you’ll be feeding your 5 plants a total of 10L of nutrient mix per week. That’s 2 x 5L bottles. You can feed a little each day ( -+ 250ml ) or about a liter ever second or third day. Just remember to give your plants 1 day per week of plain water. You want to make sure your plants are not being overfed. Look out for crispy edges on your leaves or any spots or burns. If this happens, dial your feeding down slightly and flush with plain water for a day or 2.


By this stage you may be finding it too expensive or difficult to use bottled or filtered watered. It’s the best but if it’s not an option, you can start using tap water on feeding days. The nutrients we add will help lower the ph. Remember, cannabis in coco wants to be in a slightly acidic ( low ph ) environment. If you’re going to use tap water, use water from the house and not the garden and leave it in a large bucket, uncovered, overnight, so the chlorine dissolved off.


We like to give our plants a little bit of plain water before each feed so that the medium is slightly wet and the nutrient mix doesn’t go straight through. We still want to be watering and feeding down the side of our bags so the roots have to move out to look for water, therefore making your plant bigger and stronger. Make sure the nutrient mix doesn’t splash onto your leaves. This will burn them. If this happens you can spray the leaves with a little bit of water to rinse them. Feeding and watering is best done during the day when the water can be fully absorbed by the roots. Foliar sprays are best done at night when the leaves absorb better and the sun won’t burn them.


This month we’ve moved into bigger grow bags so you’ll give your plants 10L of nutrient mix each week ( instead of 5L ). You can mix up a 5L, use what you need and store the rest in a cool, dark place. Always shake the bottle well before feeding. You’ll be using 2 types of food, a “grow” and a “bloom“ in different quantities. You’ll use the syringe to measure the nutrients. Remember to wash the syringe out properly after each addition. The “grow” is in the bottle with the black lid and you’ll add this to your water first. In week 1 and 2 you’ll add 7ml of “grow” to each of your 5L bottles. Then you’ll mix thoroughly and leave to stand for 5 mins before adding the “bloom” nutrients and mixing well. This is in the bottle with the white cap. You’ll add 5ml to each of your 5L bottles for week 1 and 2. Then, you’ll leave the mix to settle for 5 mins before shaking well again. Now, you can start to feed.


How you water and feed will depend on you, your grow and your environment. You want to feed the entire 10L per week. You can do this as small daily feeds of around 250ml or about a liter every second or third day. It’s important to stop feeding or watering when you see it “running off“ ( coming out of the bottom). Make sure to check your plants regularly. If you bury your finger into the medium, it should feel damp and cold up to the second crease (about 5-10cm). If your finger is dry or warm, it’s time to water and feed.
