6 is bettter!! Have you calibrated your meter lately? Mine has to be calibrated all the friggin time. How are your rez temps? With the lucas formula I have to add cal mag. Not saying thats your problem. Give them some time to recover now that your parameters are getting better.

i calibrate it every week... i think maybe, a lack of cal and mag is my problem... i was researching about this problem, people say, its magnesium deficiency or something..

now, i just saw, it is mag deficiency... look at this picture, they compare between two set of leaves...

how do i cure this, how do i add more mag? i read that someone started adding Cal Mag 2ml per gallon and everything turned out better than expected... where do i buy this stuff from? (for plant.)

I've done quite a bit of hydro, and it is pobably a combination of your PH being 7 and high temps. At 7 in dirt you're still OK, but in hydro your nutrient uptake window is much smaller, and at 6.4, 6.5 deficiencies, and partial nute lock. I say partial becuz at 6.9 some of your nutrient solution is being drawn into the plant just fine. The problem is not all nutrints and micro nutrients uptake at the same PH levels. Get your PH south of 6 and you'll have healthier hydro, and you'll see yourself spending less on fertilizers and additives too, cuz you're girls will actually use the shit they are already getting. I including high temps becuase in general temps of 85+ just complicate shit. Be it bugs, nute locks, mold, what the fuck ever, high temps or humidity just make recovery slow, and hard to diagnose, at least in my very amateur opinion.

Get the Jorge Cervantes books, they are on the net in torrent form. Great tools there.
