PPM Readings

[meowth]

Growing in soil. Fully nuted water reads 950ish on the ppm meter. However, fox farms recommends 1540 to 1680. Does that mean I'm suppose to add more nutes till the 1540 to 1680 number? I'm already going by the recommended nutes in the feeding schedule. I'm confused.

Please explain.

recommended reading is YOUR reading LESS the original unnuted waters reading.
what a bottle says is different to the schedule on FF website. Bottles are a guide.
If you have taken readings correctly and added the correct volume of nutes they say.... your final reading SHOULD be the same.
If not.... you have either done somethings wrong or your meter needs calibrating. I have never mixed up nutes to a manufacturers recommended volume and NOT achieved tyhe same PPM/EC that they state it should be.
If it's reading thatr much less...... there IS something a miss somewhere.

Fox Farms nutrient schedule is mapped out primarily for heavy feeding plants such as tomatoes & other high feed crops. For MJ I sternly advise to go 1/4 to 1/2 strength on the full nutrients & additives all of the way through. Both myself & a ton of other people have scorched the shit out of their plants using FF both in soil & hydroponic applications. Start at 1/4 to 1/2 the recommended does & if your plants seem to be growing slowly, bump it up in 1/4 increments until you reach full strength if necessary.

Yes, that much I knew. I don't get to full strength until the 2nd or 3rd week of flowering. I thought the fox farm schedule, available at their website, was for MJ, even though it didn't say it exactly. Do tomatoes have an 8 week flowering schedule?
