You need to find out the pH of your water/fert mix.

Doesn't look overferted at all. Looks like high pH led to nute lockout. But then again maybe its burn from something other than N? N overdose will turn the leaves dark green -> brown and crispy -> death

You can make do with a cheap pH pill tester kit from wal-mart or lowes/depot

I actually had a N deficiency till I checked my tap water with a pH tester. Since then I add 1tsp of vinegar per gallon of water and now all my girls are growing fine

JUST CHECKED THE PH OF MY SOIL ITS SITTING AROUND 7.2 AND IM PRETTY SURE THATS HIGH SO IM GUESSIN U HIT THE NAIL RIGHT ON THE HEAD SO WHAT DO I DO TO BRING IT DOWN AND KEEP IT DOWN??????

I'm not a soil guy, but I know you want it around 6.5
i would wait until a soil guy can give advise
but here goes anyway...

i would add some "pH down" to a few gallons of regular water until its around 6.0pH. then try flushing her with half of a gallon first, and then wait awhile and test the runoff water's pH. keep doing this until the pH is 6.5. Then always make sure that after you add the nutrients to your water, the pH is 6.5; if not correct it by adding either a little "pH up" or a little "pH down" at a time until its the magic number

anyone else got a take on this

johnny-0

Yep,Soil should be 6.5PH.or as close as you can come .Ill bet you have a deficiency in magnesium unless you have been adding cal-mag. during your grow.Miricle grow contains no magnesium and is notorious for mg. deficiencies.

breezybong12

i havent been useing cal. mag but i can get my hands on some if its gunna help also the thing about about vinager does that really work to lower ph of the water and can it be used with the nutes?

johnny-0

Yes vinager lowers PH and can be used with nutes.I would stop the spraying of neptunes seaweed.Used during veg. but not that great in flower.Your sativa dominant plant probably is not as big of a fert.user as you think.I would cut back on every fert. your using by at least half(leaf tip burn) .Also,when you pick up your pot -does it seem Heavy.I think your watering to much .Remember LESS is probably the best! PP. SS. FF-Cha-Ching is used during last 2 weeks of flower and it looks to me that you have a lot longer then that to harvest.FF-BB is perfect for every water low dose.

Listen to johnny-0!
