Rapid growth with my 240 watt HTC LED

I'm showing 4 nodes on one and 3 on the other from seeding. Will FIM both for scrog. I'm waiting to have somewhere between 4 and 6 nodes before FIMMING. Should be within the next 2 to 3 days. Should I start nutes at half dose than or wait. Trying to improve on my second grow

To be safe I would nute at a quarter strength just to see how she reacts and move up if she responded well to that dosage. Better safe than sorry. Good luck bro.
