    Default Not sure what this is, don't want to nute burn trying to guess a defficiency

    So I have 3 girls going on week 4 or 5 now and everything has been going smooth until recently. The three strains I have are Blueberry, White Widow and Mataro Blue, all of which have been getting the same nutrients (Remo) following their schedule. The white widow looked to get some nute burn recently and had some white salt collecting on the surface, I guess it can't handle the nutrients the others can. I gave it half the nutrients on the last feeding, and it didn't seem to help so I gave her a good flush last night which looks like it may have helped. However now this Mataro Blue is getting these black spots on a few leaves, what does this look like?


    Here are two screens of the Mataro Blue with the dark spots you will see on a few leaves

    This is the White Widow that I think had nute burn, this is now 16 hours after a flush with pure 5.9ph water only

    pH going in is 5.8-6.0 and run off that I just checked that has been sitting for 24 hours is 6.6, and no they are not sitting in the run off.

    They are getting MagNifiCal 3-0-0, VeloKelp 1-1-1, Micro 3-0-1 and Grow 2-3-5 based on remo nutrients schedule.

    The ppm works out to be between 850-1000 in week 4 and 5

    They look very green and there is clawing on some of the leaves that I think suggests you may be overfeeding. No expert though, someone more experienced will confirm (or call me an idiot) 😀

    Also, don't follow manufacturer's feeding schedules religiously, rather use it as a guide. Every time I've followed a schedule, I've overfed. Rather watch the plants. An underfed plant is easier to work with than an overfed one.

    As noob said. Don't feed every time.

    Your plants are only 4-5 weeks old.

    (as long as it isn't a seed mix/light mix) Soil should have enough nutrients for a month. Maybe into week 5 you could give a dose of half strength nutrients and then wait and see how that goes.

    My plant is 71 days old and only had nutes 3 times.

    Growing different strain is always tough, and adding white widow to the mix makes it harder as she eats less than most strains. You’re gonna have to reduce how much you feed her, and the rest of the plants. They look a touch over fed. Just give water for the next few feeds. Let them eat what they’re holding. Then add some feed when they pale up a bit


    Read the plant, not the instructions on the bottle.

    Exactly that mate, dark green and clawing are signs of overfeeding 👍

    Hes growing in coco mate so a completely different ball game, youre spot on for soil but coco is inert and holds no nutes so we need nutes every feed and feeding every day

    Bollocks, your right there.

    Sorry I read that as 80pct soil.

    Cheers WF420!
