You know the thread but it's a good read for this.

You don't need that high temps when using LED. Lower temps (lower transpiration to be precise) can be compensated with higher EC. You have to test what works for your set up but 2,5 mS/cm is not unreasonable.

This is interesting. This is a new prob for me, I have been growing for 7-8 years and have never run into this. I literally replaced everything (except the light but thats only a year old) I will try to raise the ec to see if this works. I appreciate all your help and guidance. Thank you. Also I am using RO as tap where I live is no bueno.

Raising the EC makes sense if you cannot raise the temperature; otherwise raising the temp is the better solution.

Fertilizer is cheaper than heating though.

True, but it doesn't change the fact that growth will be much faster at optimal temperatures rather than too cold temps with an elevated EC to compensate.

Jesus christ... has anyone reliably solved the issues of weak growth in early veg under LED? What's the answer????

Honestly I'm thinking at this point to just get myself a t5 fluoro and go back to doing it old school. In all my years growing, I just put plants into coir, fed them 1.0ec of a base feed, and stuck the fluorescent light on them and watched them boom. two weeks and a pot up later and I'm almost...

Iv'e read this, I've always only grown with LED. Never ever had an issue until recently. 4 bad plants out prob 80 ain't bad i'd say.
