ppm through growth

what are ideal ppm readings for seedlings, maturing plants, and adult plants? I know it may vary by what strain, but I was just curious. Peace.

Well there is a chart in the FAQ section that shows you that for General Hydroponics 3-part nutrient formula. Each company is different, close but different.

its generally a good idea to start out with only half strength for everything. this way you wont burn the plants. and make sure your water ph is about 6 before using so you dont get nutrient lockout.

ph= 6.0 to 7.0 is Ideal for sprouts thru out bloom. But ckeck it before adding nutrients and re check it again after to make sure it is still whrere it should be. Diferent mediums/soils as well as nutrients can change the ph and this may result in poor growth and other problems.
Good Growing!!

This is the Hydroponic section and Ph that high can kill plants. Ph that high is more suited for dirt farming.

Hydroponics Ph is 5.2-5.8 for the best growth.

The Ph chart in the FAQ showes you the available nutrients at different Ph levels.
