With the GH 3 Part, could I use it even though I'm not growing hydro?

If I go with an all purpose, I take it it should be 5-5-5, 10-10-10, or 20-20-20, something balanced. I noticed GH 3 Part isn't as balanced as all purpose. Since I'll be at a store with hopefully a variety of options to chose from, which would be best as far as 5-5-5, 10-10-10, and 20-20-20?

I was also unaware of how beneficial Super Thrive is. I read the Super Thrive thread. I was under the impression that it would kill/harm a young plant, or burn it somehow. I had no idea of all the uses!
horror business Reviewed by horror business on . Transplanting Question I have four plants all 2 1/2 weeks old in 6" pots. They are starting their 7th node, and are all short and compact due to me keeping the lights extremely close. Anyway, root hairs are coming out of the drainage holes. Obviously I need to transplant. The problem is, 2 out of 4 of the plants need to be fed fairly soon, as they are starting to show a nitrogen deficiency, and the cotyledons are yellowing and falling off. This is normal for their age. So, I need to know, should I feed them Rating: 5
