yellowing

Hey, im quite concerned as it is my first grow. I have a few plants in a small tent under 2 55W cobs. This particular auto is in week 8. I know my yield will be quite low. The plant has started turning brown in the upper leaves. I thought it was nute burn but after flushing it just got worse. I...

All the same soil and same strain. And up until yesterday same nutes. I was forced to try a nitro boost on the 5 that are yellowing. Tomorrow I will rotate. Just wondering what are the chances I got a bad bulb they are brand new this grow. All 10 are heading into week 5 flower. All buds are...

Single-plant, micro/stealth indoor grow. Indica dominant strain. 7.5 weeks in flower. Medium is 30/30/30 soil/coco/perlite, but the "soil" is also 50% coco (weird I know but not the topic, just FYI). I have treated more as if a straight coco grow. As a micro/stealth grow, this has been CFL-only...

hello everyone, still kindof a newbie here, finishing up my second grow (just started flush) and I'm starting to raise little ones for round 3. Some facts about the clones pictured: -every clone in a cup / pot / bag has rooted (aeroponic bucket transplant to medium after roots) -I use Pro-mix...

Ok guys, I have 8 clones that have successfully rooted in my DIY aeroponic bucket things, but it seems after transplant a few leaves on them are yellowing and even falling off/dying. I transplanted them into small foam cups with a coco/vermiculite 50 50 mix, and they're positioned the same...

so I’m growing some tsunami web outdoors in North Carolina and am about 4-5 weeks out from harvest I believe. My recent ph test results came up with a 7 for every single smart pot, almost exactly. It’s usually more at like 6.3-6.5. Should I be worried? I don’t have any ph up and down because my...

What is wrong with this one? Recently changed soil and pot. It's like they start turning yellow from the bottom to the top and getting some brown spots aswell. Can they still be saved? EDIT: They are about 3 weeks old and it started after I changed soil and pot. Soil is same type as in the...

Havnt been checking on my plants for a few days then found theses perfectly round dots on some leaves (upper and lower) on only one plant. See for yourself... The one leaf that has the yellowing was the only leaf like that and I pulled it. Could be two different things?

My 4 girls look decent but I noticed some of their bottom leaves yellowing. They have been in dwc buckets for almost two weeks. Ph stays between 5.8-6.5, ppm 300 (120 tap water) some grotek kickstart and a little calmag also some uc roots for sterilization. Water temps at 72f. Hopefully someone...

Hey everybody, I'm just wanting to verify that this may be a Cal-Mag deficiency. Blue Dream, started yellowing and one leaf is "crimping" upwards. This is my first grow, hoping to start journal for help. Light: Hydroplanet™ 600w Air Cooled Tube Hood with dimmable ballast(MH Veg, HPS Flow)...

Not new to growing but new to hydro. Have a RDWC system with two 5 gallon buckets filled with hydroton. Plants are around 4 weeks in the pics. The one is absolutely fine. Looks great and how it should. The other one looks like death warmed up. This problem started almost right away when it was...

Hi everyone, I'm new to the forum and I hope you're all fine and high. I'm writing cause one of my 2-week-old auto-dinafem white widows started showing a strange yellowing on its second set of leaves like 4 days ago, and I can tell it's getting worse as the days progress. I'm pretty sure it's...

First up this is my first indoor grow. Seedlings pictured here are Skunk #1, CBD Shark Shock and Tickle Kush. They were all germinated at the same time 7 days ago and put under a 6500K 150W CFL 3 days ago on a 18/6 timer with a oscillating fan. I am using a seedling mix of coco and no nutes as...

Started a new thread as per suggestion,accidentually posted on a bumped older 2009 thread... Using Single mars 300W led and plant is at least 12" from the LEDS with no signifigant heat issues from the light or room. (Temps never lower than 65-70 to as high as about 78 to 80 on occasions) My...

I have been searching on line and am thinking it might be due to potassium or possible magnesium. About a month ago I noticed black spots on about 3 of the bottom fan leaves, the next day the spots were on about 5-6 fan leaves and I cut them off. When I woke up and checked on her there are spots...
