Little brown spots???

[fozzy]

[fozzy]

So I use fox farm ocean forest. With fox farm nutes at 3/4 strength. I use cal/mag a couple times to see if that would fix it. I have flushed a couple times. Ph around is 6.5 every time I water. I use water only ever other feeding. (RO wateris used)
I do use optic foliar "overgrow" Ive searched this website and others to find what is wrong. I can figure it out! Any suggestions would be greatly appreciated! Thanks!

Whole plants pictures would be good. Help the helpers see the whole plant if you can.

looks very similar to same thing I got going on my newest plant. hoping to post pics and ask for opinions in the morning. will see what we both get for answers. only third grow so new and at a loss on this one. all new growth in roots leaves and stem doing great so hoping doesn't spread and kill her outright.

where do you get your ro water from...I suggest bringing down your ph to 6..what is your ph on run off water...I bet your high...ph I mean..lol

[fozzy]

I will try to post some pics soon. Water comes from a local shop. I haven't tested run off in a while. I will have to wait a couple day to do that. The plants over all are pretty health. Most of the spots show up on the bottom leaves. I only have a couple leaves that look as bad as the one above. Thanks for the help guys!

I run my DWC system closer to the bottom of the scale for ph (5.5-6.2 is the scale) so your ph is too high... I use botanicare pure blend pro full line and never had any nute burn of any kind so can't help u there but I would start by bringing your ph down, I've found that my plants look healthier and stronger when I run my ph around 5.6-5.7 but I DWC n that totally diff than dirt so?

Ok here are some more pics of the plant. And another leaf with the spots. I am going to try to flush check my ph.

This is my first grow so I will take all the help I can get. During my flush I had a ph of 6.3-6.5 coming out the bottom. I did ph the flush a little lower though.

[fozzy]

Also I had 6.7 ph at the end coming out the bottom. Also this girl is in her second week of flowering

[fozzy]

So what do the helpers think? Could it be a boron deficiency? I'm going to run my ph around 6.2 for a while to see if that works.

keep ph at 6 ...it will get better

6 is the magic #
Although some peeps adjust for certain strains and or soil.
6 is perfect for coco
IMO

Thanks I will do!

hey fozzy mines a lot younger but had same as yours. searched ph on the gwe page and they have a graph of what ph different chems absorb and they say some fluctuation is good. started new water change just under 6 ph and let it climb as it does. working out by the time its getting to high its time for a water change. pretty much have the damaged leaves trimmed and things are looking good. good luck
