Spotting...

Changed out the water in the res a few days ago and added new nutes... today, noticed spotting, drooping, and a general fading/yellowing... Nuteburn, pH problem / lockout, or deficiency?

Hydro/Aero system
pH when water was first mixed was way acidic, checked now and it was around 6.5... i just brought it back down to 5.5-6.0.

Thanks

keep your ph at 5.8 and a lot of your problems will disapear,it needs to be in the zone so the plant can up take nutes evenly,when the ph is off it locks out some nutes,so you get problems.

cause and effect is the name of the game

thats what i figured, it looked like it locked out Mg (also because of the ca in my hard water) so i added some espson salts... springin back to life a bit
