best way is to start at 1/4 strenght of recommended amount and slowly increase to corrrect amount -this way you should not cause any nute burn - also depended upon what grow media your using and stage of plant - for veg i use something that has high N value then foe flowering a high P k value
I would start out using the first time you feed half the amount recomended and see how your plants respond. The following week if there ok do the same and then you could increase the amount each week to what the recomended is and continue this until flowering if your plants appear healthy. Once flowering you will need to change to a flowering fert.
Right..... Nitrogen, Phosphorous, and Potash (Potassium), which we can also describe with the letters N-P-K. 5-10-5 0r even a 10-20-10 when flowering..
After the first couple of feeds. If I were you I'd buy some better nutes. A nute with more K. Something like 10-5-10 would be better. The K should be almost as high as the N.
My friend has been watering his plant everyday with 20-20-20 mixed 2tbsp per gallon. Ofcourse this plant is a small tree, but I didn't think it could handle nutes everyday.. no burn yet though.
