My tap water is 70 ppm. I'm using 5 gallon pails to fill and let sit to dechlorinate and also get the water to room temp before I use it for watering/feeding. Plants still continue to look a little Nitrogen heavy/toxified. Going to skip a few feeds and stick with ph'd water only until it clears up. lower leaves are dark green at the tips and clawing. that's what is making me think that it's early N toxicity. June 5th - light water, ph 6.23. added calmag as one plant had rust spots showing on lower leaf. ppm was 312. (water is 70 and calmag made up the rest). Calmag is 1-0-0, so should make a big difference in my laying off of Nutes for a few days. June 6th - light water, ph 6.29, ppm 70 June 8th - Nitrogen tox is pretty much gone (leaves not dark and clawing). went easy on the GH Micro nutrient to keep Nitrogen lower for this feed. This strain seems to not need as much Nitrogen as previous grows/strains. Will keep a close eye on it to see if it's def or tox in the future. gave feed at ph 6.31 and ppm 345 fed about 500-600ml per plant. should last a little longer before next watering. June 10th - not sure why, but a few of the plants are droopy. The aren't thirsty, so I'm assuming overwatering even though I've been pretty careful. I watered today during lights out and they were fine yesterday (praying and happy), Gave 400 mls per plant at 6.3ph. added 2.5ml calmag for 3 litres, ppm was 236. Will lay off watering for a few days to see if they perk up.
