^That would be my first thought...is new growth showing the same signs?that is not heat or under watering. it appears to be a mag def, try adding calmag or epsom salts.

Yes. But everything I've ever read within the 11+ years I've been growing hasyour ph is not too low, 5.5-5.7 in veg is perfect. if above poster was saying a k issue, your ph is perfect for k. it is mag.
if you will look at the chart it shows a soil and a hydro chart. the op is running HYDRO. therefore, if he took your advice he would seriously damage his plants.
do you grow soil or hydro? you go ahead and run those numbers in hydro and
report back to us. i have harvested well over a thousand plants, all in hydro, i know what im talking about.
Tap water from the city here .80 ppm from the tap! There's something to be said for diligent water treatment! Serious farmers should always check in on there annual water report the get a sense of what they'll need to do in order to make it grower and plant friendly!Being he is using distilled water, poor choice for growing, they probably are a little short on calcium and magnesium.
Glad to hear it was a cal-mag deficiency and you have it all cleared. You say your only running 350ppm in hydro...while they may be growing ok they could and should be at a higher ppm IMO. I usually run about 750-1000ppm in the beginning of veg but by time I'm nearing the 12/12 flip from 18/6 I'm at least at the 1000ppm mark if not 1200..sometimes even 1500 depending on the strain. You might want to consider giving the nutes to them till you just start to see the leaf tips browning(over nuted) then backing down a bit to stop the browning and get a benchmark # so you'll know and can document for your own records what the strain can handle. This will help you in future grows especially if your ever going to run the same strain. Just a thought for ya.I dissolved 6 tsp in a liter then added it to my 112 liter tote ph is at 5.6 but my ppm shot up to 350 from 230 does that sound like too much?
also the plant it is affecting the most has just about stop growing, tangerine dream seems to be more susceptible. The kandy kush only has small spots in the middle of the leaf.
Maybe the problem started with the water or EC.
