A question from fellow grower:
I’m currently growing in soil with a 600w HID:HPS bulb and I’m in week 1 of flowering.
My plant’s runoff keeps coming out to over 1,000 PPM even though I have only been giving her Ph’d tap water (45-46 PPM). The most recent feeding she got was 340 PPM and that’s the highest one yet. All the earlier feedings were in the 200 PPM range.
I have strictly followed the feeding schedule of FWWW and yet I can’t figure out where all the extra PPMs came from. To me, she doesn’t seem to be showing signs of nutrient burn, she’s still growing fine but I’m confused as to how the PPMs got so high without me overfeeding her. Do you have any idea what I may have done wrong?
