this is so common during flowering.

It looks like calcuim. Could be lockout or deficiency. The lockout could be caused by overfeeding, out-of-whack pH, temps... I tried treating it with everything. Finally I just gave up and let the plants finish. Other than some ugly leaves, they plants produced nicely.

If you dont know whats in your tap water, you cant know if you are overdoing it. Most people who use tap water dont need cal-mag. My tap water reads 50ppm so I add cal mag.

85f with a 1000w HPS 18" from the tops of the plants is probably causing some radiant heat issues which can cause all sorts of problems.

Raise up the light, get a fan blowing on the tops/glass and

What you spend on PH up/ down, you will prob save on nutes that are not being consumed.:clap:

do you use nutrients? My tap water is over 7 but always gets down into the low 6's after I add the nutes.

That's not good either. Fill a container with water a day or two before you're gonna water your plants with the lid off. The chlorine will evaporate out of the water. Or you can get a sediment/carbon filter for like 100.

And when it comes to growing you can't be lazy lol. You can go to walmart and get those ph test strips for cheap

Yeah i agree tho if you want real healthy plants and want good niceeeee buds then you do have to keep on top of your shit..i do have a digital ph meter with which i phed and get 7.2-7.4..and i always let my water sit for a few days with the lid off for the chlorine to try nd evaporate but i think i have a good bit in my tap cause i can still smell it after those few couple days

You dont need to let chlorine evaporate off tap water nor do you need to pH it if you are growing in quality soil.

Thats just what I think.
