Leaf Symptom
Hi Portal, been awol for minute. Hope everyone is well. Need some help identifying what this spotting is. It's a Jack Herer, about 3 weeks from seed. Growing in coco (listened to a few of you guys and made the jump), cal/mag, gh flora series nutes, ph 5.8-6, timer 400w vero 29 lighting. Oh and i did just dial up the lights to almost full, being this plant is sitting next to a Fast Buds Auto Sour Diesel 3 weeks into flower. What you guys think? I did water yesterday, and she possibly might not have needed it. Leaf Sephora? Overwatering? Light stress? Thank for any and all help.

u have everything it needs.. just run by your pH and try not to overwater some more as u said she might haven’t needed the previous watering. The lighting part.. err maybe the guys could cover u with that..

Personally I never check the PH, PPM or anything other than quantity of the run off. Why check something with so many variables that could result in a false reading. Input controls output, so if you use good media, and PH the water/feed and flush you have controlled the input. Monitor the results by looking at the leaves, or if you want to go over the top check the Brix level and the sap PH. Why stress over what you cant really control unless you really like stress.

Did you buffer your Coco coir man or did you get the bagged kind.

Didnt buffer the coco Josh, it's Canna in the bag, I've never buffered and never had a problem before. It's weird .

Generally coco needs to be kept wet by watering with PH'd water at least once a day, over watering in coco is nearly impossible if it is possible at all. Its also best to feed every day, if you think about it, coco is hydro same as DWC and DWC is feed everyday since the roots are sitting in the
The easiest way to grow in coco coir is with an auto feed, I have mine set up to run 3 times a day, at a little over 1/2 a gallon a day for 5 gallon bags now that its in early flower.
Coco coir and DWC and need cal/mag generally at full strength or above. I have seen a lot of cal/mag deficiencies but I have never seen Cal/Mag toxicity. The PH levels have a lot to do with Cal/Mag deficiency's too.
This is a great tutorial too
