Thanks Wildwelshman, that's a good ref chart. I did not have a ppm meter until yesterday and being my first grow, and first attempt at hydroponics, I have been chasing the nutrient/water devil. That being said I'm not sure it's going to get much better, but I'm trying.
Since all my plants are roughly three weeks from seed, I'm taking everyone's advice of less is more when it comes to feeding for now. Yesterday was water change day and each bucket got a fresh 3 gallons distilled h2o with 7ml micro, 7 ml grow, 3.5 ml bloom Humboldt nutes. I am measuring my nutes with plastic droppers so I know they aren't each going to be exactly the same, and I expect some variation of ppm between the buckets. However measuring ppm before and after the nutes were added, they all didn't reach the ppm most suggest ~300-400 for early veg. I am keeping a close eye on them watching for any negative changes and so far they look healthier. Even had some noticeable growth overnight. So, questions for the collective minds: Add more nutes to bring up the ppm on those lacking? Ride it out till next water change and up nute use gently then? Or quit worrying until something starts looking like death sucking a lemon?
Below are the ph and ppm readings taken during the water change:
#1- plain h2o 200ppm, after nutes 430ppm(230), ph 5.9
#2- plain h2o 165ppm, after nutes 451ppm(286), ph 5.1
#3- plain h20 162ppm, after nutes 524ppm(362), ph 5.5
#4- plain h2o 165ppm, after nutes 494ppm(329), ph 5.7
I don't want to be spoon fed, but I'd sure appreciate some feed back from more experienced growers.
Things I'm going to work on doing better...measuring nutes, adjusting ph, watering.
