New RDWC System check up.

Happy grow everyone, Today is 2 1/2 weeks of the veg cycle and I felt I should rid the plants of their lower fan leaves that prevented good air circulation around the stalk. I also topped both northern night photoperiod at the 4th node for one and 5th for the other, the one J. Herer Auto is LST only. My question is should I hold off on the reservoir change that will increase the nutrients as the nutrients are now less than the initial 200 ppm for seedlings regardless of the TDS readings, I think ph down changes the TDS and I had to add PH- to correct it almost every day. Replenishing could give me a fresh ph and maybe aid in the recovery of the plants after the stress caused by pruning, or should a partial nutrient change be done considering the shock on the roots when the reservoir temperature goes from 68 deg to 88 deg for a few hours changing nutrients? Advice is always welcomed, and thanks ahead.

I change my rez every 10-14 days, depending on how the ec levels are dropping. I have my RDWC set up so that I can pump out the system to drain everything and then refill with fresh solution. I run Jacks 3-2-1 dry mix, so my 65 deg well water hasn't created any issues with shock during changes.

sounds like a great RDWC system. I'm still using the GH Flora series, cal-mag, SI, and rapid rooter, but I've been seeing a lot online recently about Jack's 3-2-1 nute system but haven't reviewed it, thanks for the tip. It didn't take the chiller long to get the temps down, less than 2 hrs., and there was no problem with the replenish nutes at higher temperatures.
