Simple Question but can't find a dinitive answer

I am groing in coco and using the modified lucas with added cal/mag. I have my plants in veg at 70% of the lucas which is measuring out at 800ppm.

My tap water is 96ppm. So at 70%, my plants are getting 600 ppm. I want to increase and see what happens but don't want to over water.

Can someone tell me the appropiate range for ppm for rooted cuttings, seedlings, veg, bloom, harvest.

Also, if I went to DWC I would top off the reservior to maintain a ppm range. But i always wondered that if the plant is using say the nitrogen up and leaving the other nutes that as you top off, the Nitrogen ratio would be diluted and reduced. Does this make sense?

Bump...anyone

clones about 200ppm, veg ~500ppm, flower up to 900ppm? about that range

Thanks square...

Well, those are recommended levels but you should always pay attention to how your ladies react to nute levels. If I am not mistaken you can't overwater in coco since it doesn't hold much water. Also, if you really want to measure nute levels measure EC (Electrical Conductivity), because ph/EC/TDS meter combos or TDS meters calculate ppm levels from measured EC levels. Don't worry as long as you maintain recommended pH levels in your nute solution your plants take all. They are not that smart to say "Oh I should take Nitrogen now but not Potassium"
