Strange Even Yellowing

[dejayou30]

The temps are only up to 89 when I am not around to open up the curtain right away. Otherwise, the temps are 79-85. I only sprayed Reverse through week three, and may hit them again in the 5th week and it has been all preventative. I had the strain herm my first go around and had some seeds so I have used Reverse ever since.

Also, yes, the mylar is old, torn, and dingy with a year and a half of residue from sprays, dirt, etc. so its not ideal. However I have moved the thermometer around throughout the room and get pretty consistent temps wherever I put it so I don't think its creating hot spots or anything.

I'm in the midwest, so the temps are in the 80's right now, and the end of 8 weeks for me is like June 23rd I think so it will be cutting it close with the intense summer heat coming in. Last year I was projected to finish midway through June and the temps were good but I killed her 2.5 weeks before the finish so hopefully everything holds out. I'm hoping for at least 5 oz to last me until September when I can fire up the HID again.

Thanks for all the input from everyone!

dejayou30 Reviewed by dejayou30 on 05-27-2009. Strange Even Yellowing 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 Rating: 5

Deja Are you indeed spraying thst plant every other w/Reverse? I may well possibly have gotten that wrong; so just doublechecking.......
in your free time paint your mylaar flat white. Itll help cool your area too. and stop hot spots. Stay cleaner.

How is genersal growing of plant...happy orn somewhat slow?
I personallly dont like THAT much yellowing so quickly but she's pretty big so gets itw ;own evaluation. How are buds oming along? MK shoul NOT be skimpy! :wtf:

[Weedhound]

ignore reverse q's deja......whats your feeed schedule again????

[dejayou30]

The buds are coming along very nice. The growth seems pretty normal, and I examined all the main top buds last night and they are all getting very full and looking very promising. The leaves are now turning yellow from tip to base and sort of curling down and under, like a claw. They look like they did when my roots were rotted, only my roots are a huge thriving white mass so I don't know what the issue is.

I am in 10 gallon bin DWC and feeding at about 1100 PPM with 250 PPM CalMax (GroTek), 200 PPM Sweet (Botanicare), and 650 PPM PBP Bloom (Botanicare). I alternate 1-1.5 gallon of RO water and 1 gal of 1000 PPM nute/Sweet solution, I add a gallon every day and only add CalMax at the res change.

Scratch that last update. The leaves that were curled and yellowing from front to back have started turning back to normal. I think it was a matter of the pH being out of whack for who knows how long. But the fan leaves are still doing the even yellowing thing and dying by the day, so IDK whats up. But everything I can think of is in check, so IDK if its natural aging of the plant since its so huge or what.

I reckon your right natural let nature take its course.:hippy:

FOr some reason I don't think that is the case because its still yellowing at an alarming rate and still has 3.5 weeks left. But that said, I have no idea what the issue could be. Hopefully enough of the leaves stay green to feed those buds and make them even fatter. Thanks for all the help! :thumbsup::jointsmile:

Here's a pic update in case anyone is interested. I think I was overfeeding a bit judging from the yellowing edges and curling, so I did a res change tonight and backed off to about 800 PPM. Hopefully I can keep her there for the last two weeks of feeding without any more leaf loss. She is really starting to put on some serious mass, can't wait till she's done! :thumbsup: :jointsmile:

:jawdropper: Damn.
I was expecting to see some undersized, sickly, ailing plants. :S2:

I believe you will be just fine. I grow MK and she is a great yielder, even when things don't go perfectly. And even better, she tends to "auto manicure" before harvest and gets rid of most of her big leaves the last few weeks. Makes for very easy manicuring. (Can you tell I hate that chore?)

nice job there,

Haha thanks crabbyback. I have definitely had my fair share of those sickly ailing plants so its nice to have a decent one finally. Do you think my diagnosis of overfeeding was correct? And yeah, manicuring sucks, but its a labor of love. :thumbsup:
