Strange Even Yellowing

[dejayou30]

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

Here are my pics. I realized I forgot to include my pH, which is consistently around 5.4-5.9. However, sometimes when I go into the room in the morning to shut the night time curtain, the plant has consumed a ton of water and the pH has dropped to 4.2-4.5, but I immediately top off the bucket and readjust the pH to 5.5.

Any help would be appreciated!

Yo, anyone? :wtf:

Two big fan leaves are now turning brown at the edges and curling upwards, and the yellowing is spreading to the other large fans. Any suggestions? Anyone? Beuler? Beuler?

im not a hydro guy but the spots could be burn from the foliar feed do u raise ur lights

she looks kinda hungry


my question is y the reverse? and what are ur results

Just a shot in the dark but do you reckon she could be root bound.
Your plant looks real nice though.:hippy:

It does sound like root-bound,but at this point I would'nt sweat it.You'll be smokin it before it ever dies from that.The pic's dont look that bad,alot of them get yellow in flower anyway.

I see some nute burn on the leaves mainly on the tips and also on new growth.
That is just my opinion wait for replies from more experienced members.
Good luck.:hippy:
Edit, I dont spray anything on plants when in flower.

Reverse is just a hormone spray to inhibit the growth of male sex parts. I had some trouble with herms my first time around with this strain, so I've used it ever since and never looked back. I've never had seeds since. Could be my growing methods have improved or it could be just the spray, but I'm a n00b so I don't chance it.

I guess she could be root bound, the roots are a huge mass, but it seems like there is a lot of room for them to keep growing. I could switch to a larger container pretty easily, so I might try it tomorrow and see what happens. But as for now I think the leaves turning brown are a gonner.

I started using Botanicare's Sweet supplement and upped the PPM to 900 because I thought it looked a bit underfed as well, but my humidity has been low so I didn't want to burn them like I did on my last grow.

I am mainly just worried because in the past, when the big fan leaves die, the yield suffers dramatically. I am looking to yield enough to last me like 4 months at 1/4 a week. I will try a larger container tomorrow and see what happens.
