Ask a Grower

Ask-a-Grower #92

I took my clones from a little cup and I had them in fox farm for 2 weeks. my question is how long do I wait before I add plant food-nutrients-whatever. I am a first time grower. I have a 3×3 hydrohut with a 250 watt halide light. i have 3 gallon grow bags.

When using Foxfarm Ocean blend you probably want to start watching for your leaves to lighten around 2 to 3 weeks. I think because your cuttings where young and your only running 250 watts you should have 3 weeks easy. There is many variables on how fast a plant can deplete the nutrients in the soil.

1)Bigger plant size and large amounts of light will decrease nutrients faster to keep up with the plants needs. (add sooner)

2)Small or sick plants can not utilize the nutrients or light so they will have much less nutrient requirements. (add later)

3)Or maybe they’ve been watered excessively which will wash the nutrients out and lead to a waste of money and water. (add sooner)

The best thing to do is pay close attention to the color of your leaves. When your leaves start to turn a lighter green then it maybe time to start adding nutrients, maybe even 1/2 dose if your concerned about adding to much. When your leaves start getting to dark you may want to just use plain PH balanced water to give the plant a chance to use the excessive nutrients in the soil.

We hope this helps you out and look forward to answering any questions you may have in the future.
