Strange Even Yellowing

[Greenthing]

Well done, its looking fine now:thumbsup::hippy:

she's saying she's ....cramped to me.......if that were a soil plant i would transplant to a larger container based on that photo. I know she is in hydro; it just looks pretty classic However you are right in the middlle and MK is quick finisher as a rule so if you want to try to just finish out thats good too.

Hey.....whats the ph story?

I've moved her from a 5 gallon bucket to a 10 gallon tub a couple weeks ago, and she's only filling up about 30% of the bin so I don't think she's root bound any more. The roots can't move down very much farther but there's a little room, and there's TONS of room to the side of the root ball. I tried cracking the ball open a bit but its pretty solid and I don't want to break any of the roots, and the inside of the ball doesn't look like its rotting or anything and I'm pumping 40W worth of air in there so I think the roots are doing alright. I also got new air stones because a couple of mine were clogged a bit, so now its getting even more air.

The pH was out of whack for at least a week because my NutraDip Tri-Meter shorted out on me. I was a little skeptical of it constantly reading 5.3 day after day, so I checked it in my other buckets and it stayed the same and I knew something was up. I tried to calibrate it and it still read 5.3. Then I unplugged it and plugged it back in and it read 16.6 and wouldn't move. I had to send it in, but the good thing is, the guy that owns the hydro shop I go to is going to give me a FREE replacement ($250 meter) for being a good long time customer so I don't have to wait 3 months to get a new one back from the manufacturer. :thumbsup::thumbsup::thumbsup:

I've been using an Oakton pH2 and keeping the pH at around 5.5-5.8. The PPM is around 850 right now, so hopefully some of the leaves come back.

Not sure what else to do. :wtf:

Dunno dude. Got nada experience with DWC or any nutes other than the Advanced Nutrients line and molasses.

She looks real good to me. She's just using up the N in her fan leaves because she's not getting as much as she wants when you feed bloom nutes. Excess N during bloom stifles bud production and increases leaf mass, certainly not what we want. :weedpoke:

You said she would be finishing up around June 23, right? That is only 3 weeks away and in another week or so, you will start flushing, which will cause increased yellowing. I think you are just seeing the natural progression of the bloom cycle with MK.

don't worry, be happy

I have a Master Kush plant that is about 3 months old and is on day 17 of flower. I have noticed the big fan leaves have started yellowing very evenly, and it is a dull color of yellow. Some of the big fans are now getting tiny brown spots, and it is also starting to spread to the other newer growth too.

Its dark time right now, but I will have pics ASAP. But if anyone has a clue by this poor description, please let me know so I can take action right when the light comes on. Thanks in advance! :thumbsup::jointsmile:

Here's my stats:

Approx 3 month old plant, day 17 of flower
5 Gal DWC
2 4" cylindrical air stones with a bubble rope around the outside run off a 19W industrial air pump.
Sits in 2-3 Gallons of RO water with 400 PPM Pure Blend Pro and 200 PPM of GroTek CalMax
Have been foliar spraying every other day as of day 14 with Dutch Master Reverse (2 applications so far)
67-69° water temps
78-85° Air temps
35-45% RH

Master Kush seems to do that alot, but I usually keep giving them plenty of N. Botanicare has a good product called Power plant. I would add a little of that about now to your mix. I usually add Power Plant first then the flowing food after I mix the power plant. You may be able to just use a bit more of Cal-Mag by Botanicare Its also really good when using distilled water, but if your using tap water, Power Plant I think would do it for you.

Cal-Mag by Botanicare Has alot of N, but you know to decrease that toward the last 15-20 days:smokin:

cool deal with the new meter. :thumbsup:

[dejayou30]

Cool, I think I will just keep caring for her as normal and hope you are right about consuming the leaves. Today is Day 35, so I'm on the home stretch. Two more weeks of feeding and then the flush. Thanks for all the help, and I will probably post some more pics in a couple weeks so you can see how she ended up since this has pretty much become my grow log. Thanks everyone! :thumbsup::jointsmile:

Started a log for my last couple weeks of flower
