how big does the the plant have to get before you can start adding nutes. and i was also wondering if miracle grow is ok
HIGH All, I wait till at least the 2 week mark and then it's 1/4 of what the dose say's on the instuctions. Don't use MG, but it'll work...just remember not to give it to much from the start.
nothing. MG does great at what it was designed to do. Unfortunately, it wasn't designed for growing pot. I've used it before with decent reults, but I prefer a nice organic fert. If you do use miracle grow, I would definitely mix it at 1/5 - 1/4 strength to start off and probably never even work up to full strength. If you want a good, basic, cheap fert for your first time growing, go with Schultz AP Plant Food http://www.schultz.com/ProductCategories/GardenFertilizer/AllPurposeLiquid/ and don't mix it full strength. Gradually build up to full strength.
Another good brand of nutes is Foxfarm. I bought them on Ebay for about $10 a bottle. Not the cheapest but far from expensive. I usually wait until the three week mark before adding any nutes. And when I do its usually 1/3 strength grow big and big bloom together.
