Plant Problems...again

Growing in Fox Farms Ocean Forest...
Using RO water....
Outdoors....
Hana Ph meter everything to 6.5
Found out that using RO water will cause Cal Mag problems....went and bought a bottle of Cal Mag. Started adding 3-4 weeks ago when this problem first appeared. I haven't been using every watering....should I have been?

Did a soil flush with several gallons of RO water yesterday and today...checked runoff PH by adding 7.0 RO...then checking runoff, it's at 6.5

Last used nutes (Botanicare Pro Bloom) 9 days ago. Old fan leaves are being affected first, then older leaves.

Funny....my plants always look terrible after a rain? What's going on here?

Thanks for the help....

first photo didn't open for some reason? You can click on it and see a different photo. (leaf close up w/burn?)

THANKS again!!

looks like an N deficienecy.feed her! use regular tap water. no need to buy ro water when weed needs chlorine to live anyways.I didnt see you fed her 9 days ago! thats awhile without nutes for a flowering plant,thats when the most growth is done.

They are hungry feed them. 9 days without food is a long time in flower.

looks like lacking nutes to me. you say its worse after a rain, well the rain is flushing out the nutes.

Been staying to the directions...1tbs to a gallon of water.


I tried using tap water....makes them look like they do in the photos. I'm in Az with super hard water. Went to RO water and they looked 100% better at first.

those are budding nutes you still have to feed them micro nutes and grow nutes ust lesser amounts

I was using Botanicare Pro Grow till they started flowering...then switched to Pro Bloom. So I should still be feeding the Pro Grow as well? I also using Botanicares 'Silica Blast' to help w/heat. It's just a phosphate.

needs more nitrogen, switched to bloom too early

When I was using RO I was a stickler and always calculated out the ppm of all my nutes. Kept cal-mag at about 100-150 ppm usually.. I used those free calcs on the nute websites (GH had the best one). During flower I kept N at 50-85 ppm and P at 140-190 ppm, didn't have any problems, but every strains different so you gotta tinker with it a bit.
