4 weeks into flower, im in soil with natural amendments. Recently tested ec(4.1) should i flush till at 1.9? Any recommendations

My temps do fluctuate more than ideal thru the day. They go down to 73 and up to 90f. im still trying to get them more consistent but have been loosing that battle.

I have 2 mars 1000’s. their aprox 18” above canopy and still at 75% blast

Thats what i thought, the ph is 6.5. I heard on your podcast about the ph and ec not being critical when doing organic topdressing, i guess that there is still an acceptable range to stay in so the plants are happy? I did flush it down to an ec of 2.1 36hrs ago so fingers crossed.

Wow that's a very high EC. You're probably encountering deficiencies due to nutrient lockout. A flush may be necessary. Do you know what the pH of the runoff is?
