DID I JUST HURT MY PLANT?

I am in week one of the flowering phase, and my chart i have says to give my plants 7.5ml per gallon of my blooming fertilizer and i gave it 20ml. Now that chat im using says in week 2 of flowering to give it 20ml per gallon, but like i said im in week one, beeing new to this whole thing ive been doing pretty good my baby's are growing up stong in front of my eyes, im just worried that i might of just fried them?????? am i ok if this just happend once? should i do anything? please i need help from someone who has been there and done that...

I dont use hydroponics but I will say that you should stick to your guidelines, especially if you are new to it.

If you start to see browning on the leaves then start worrying. Can't you dilute the medium to bring it back to 7.5ml ?

Anyway, if you want to take the chance and leave the 20ml in there then go for it. If it survives the week the just don't add the full20ml the following week. Add15ml, and then go back to the guide lines.

Take care
