im on my second grow now and in both of these my ec has gotten out of hand and caused issues with my plants. How do you guys keep this from happening. I have a ec pen to measure it, but i dont want to just keep having to flush my plants.

Synthetics are usually required weekly and cause salt build up that require flushing. in fact very popular feeding charts schedule flushing as a part of the feeding plan. Feeding the soil and letting the plant take nutrition as required doesn’t require flushing and doesn’t cause deficiency/toxicity.
control pH by using dechlorinated tap water and add Cal-Mag+, then reduce pH to target using phosphoric acid or raising pH to target with baking soda. After that, add bacteria and microbes (don’t adjust pH after adding them). (Recharge, Mammoth P, etc..)
then, feed the soil natural ingredients vs feeding the plant synthetic ingredients. (Dr Earth, Gaia Green, Earth Dust, etc…). Usually these feeding charts recommend a feeding every other week. Water with ‘dechlorinated, Cal-Mag+, pH’ed, microbe water’ as needed in between feedings.
the microbes and bacteria buffer the soil (aka provide resistance to pH fluctuations) and prep the nutrition so the plant can use it easier as it needs it. Granted it takes longer than plant ready synthetics but there’s no flushing.
