See, this is exactly what Im talking about! Which way do you go? What it appears I have or had, is a calcium defficiancy, low nute concentration,did a res change, got rid of the FoxFarm and went with AN sensi grow, I upped my ppm to 550, all the new growth looks good, in the last 2 days, they are taking off...this whole first grow of mine has been hit or miss, 10 different people, each telling me to do something different, glad Im keeping notes, because my next grow shouldnt be nearly as farked up as this one has been, plus I dont even know if they are girls yet! yessir....real pain in my ars!
