Have you considered maybe your giving them too much light? Ive seen 'nutrient deficiency' symptoms occur when plants were receiving too much light along with too high of leaf temperature.
Are you on the lowest setting? 600?

only run I gavita at 1000 watts about to turn her right up, 4 plants under, just lowered them down to ground level, are now at 36 inches, done three runs under 1000 ,finish around 24 inches and less with no problems, have been veged under 2 cfl's then 600 gavita for week then to1000. maybe you answered your own question with to much light and heat?[URL=https://www.icmag.com/ic/picture.php?albumid=49972&pictureid=1311927&thumb=1]View Image[/URL] BEEN UNDER THE 1000 WATT'S FOR 3 DAYS HERE.ON 1.2 1.4 FEED.
So...I may have 8 Gavita classics for sale in a few months if anyone is interested. Only three pulls on these bulbs.
What medium do you use?
How many runs have you done with deficient looking plants and not tried adjusting the feed levels?
Its a common topic in this very thread, many folks have had to bump their nutrition levels...
I get the same chlorosis but the usual dose of Epson salts or this lately seems to fix. cmx. here's a shot of last nights new growth you can see at 1000 at 36 inches. wonder if it is your combined lighting = like over lapping lights to much??Yep. 600.
Chlorosis across the plants. Happens every time. Every strain. Then I spend the rest of the round trying to chase health. Not falling for it this time. I need to figure out whats up before they get flipped.
I know it's not heat. I dropped $4k on a really great 3 ton LG Split right before the second round.
Humidity @ 40-55. Temps 70-80. CO2 @ 1200-1400 ppm. Conditions in the room are fantastic.
I'm wondering if I just need to get more spread between the canopy and lights. But I'm at 3' above the canopy.
have you seen the gavita master controllers, sense the heat etc and auto turn down the works. on the gav site.
