How's your air circulation? that spotting looks like cal mag defecicency, but could be a ph issue

When you say Ph seems to be fine, what are you really saying. What do you run your Ph at with your feed inputs?. Whats the Ph of your medium.? What is the Rh of the room some of that stuff looks like PM but its hard to tell from the pics. When seeking assistance always post as many of your enviro parameters as you can along with pics as clear as you can get them. Welcome to the farm!!!
and dont worry about the ebola comment from knucklehead. Some folks forget we all started out not growing stellar erb right out of the gate!!! I wish I could be more help, need more info.

You are running too high in my opinion on your Ph. You are locking out some vital nutes the plants needs. Coco is considered to be a hybrid form of hydroponics and as such the ph range is identical to hydro, however this is strain dependent as some strains respond differently.

Rh is relative humidity. How much water vapor is in the air in your groom.

Here is a chart that shows what the optimum coco Ph range should be. As you can see at 6.7 you are missing some key nutes.



In addition, what ppms ar ec are you feeding your plants ppm = parts per million ec= electrical conductivity.

I use a bluelab truncheon for ec ppm, but they are pricy you can get a decent ph pen from hanna or Milwaukee for about 40 bucks. Be sure to pick up ph 4 and ph 7 calibration liquid as well and calibrate bout 1 time a month.

Wrong chart my dude...6.5-6.7 is ideal in soil grows. Doesn't sound like you're running cal mag at all. Aim for a fluctuation in your ph, outdoor ph goes up and down all the time, you'll need to mimic that lifestyle the same indoors. Three things that speak out to me are PH, PPMS and cal mag, get those in check and watch your dosage. You only need about 300 to 350 ppms in veg. I only push my dwc hydro to 475 max and that's in bloom. The plants gonna decide what it wants, you can always shoot low, but once you give to much you're in a position where you need to flush to escape lockout. Otherwise dude plants looking healthy and moving along nicely

I thought dude was in straight coco until he qualified. You are correct soil only Ph levels is different than dro. So I wasnt wrong per se, just misinformed......... :D

I thought you were in coco. I looked back and didn't see any reference to soil. Is it coco or soil?

THANKS!!

whats a RH??? my PH is at 6.7
I have been using speedy veg , BushDoctor "BEMBE Sweet and Dandy" and Flower Fuel for flowering plants. As for veg plants I been using speedy veg and fox farm 'Grow Big" both in DR. EARTHS 'POT OF GOLD" soil with added Coco coir, perlite, laval rocks and styrofoam for drainage. I need to get a better ph tester and a EC tester and learn how to measure out the PPM of the nutes , any recommendations where to buy the testers and also how to measure out the nutes???"


I listed the new things I bought in my original post, but I did mention I'm growing in soil and just mixed in coco coir, laval rock and perlite for added drainage. So yea, its 75% soil DR. EARTH'S " POT OF GOLD" and then 25% fillers for drainage. Any thoughts?

I Grow in straight Coco and don't have experience indoor with soil so I wouldn't risk tossing out advice on something I don't really know. Def listen to the soil guys

I had something similar in my coco dtw system. I believe I was locking out P due to a ph pen issue. Lol.
But like I said that is coco.

AHHH ok, thanks all the same! But can I use the same PH pen as people that grow in coco?
