Grow Mediums General hydroponics seedling feeding question....

[AndyBotwin]

Now I'm confused.I thought it was standard procedure not to add bloom nutes until they go into full flower but at 1ml per gal I guess it won't hurt any thing.If in doubt follow the manufactures feeding chart.They have done testing and usually what they say works.

Agreed but with GH, or at least the Flora series that I've used, you combine the Grow, Micro, and Bloom together from beginning to end. The ratios change depending on the stage of growth, but you never fully switch between one or the other. They call it the building block system or something like that:

I usually don't use cal /mag until the plants get a little bigger,maybe a light dose at two weeks old.

Never used flora series so that's cool. I'm using Dyna/Gro and they don't recommend bloom nutes until week four because there veg nute contains small amounts of phos and potassium.As long as they get a little extra phos and potassium when flower starts it's all good.
