deficiency

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...

Hello All, Looking for a little help on my auto flowers my one plant seems to be growing extremely slow but looking okay and then the other one is growing at good rate but the lower fan leaves slowly start turning yellow and dying one at a time from the bottom up. I know the first couple sets...

I noticed some spots on my plant this morning so I was reading up on what it might be. I'm thinking it could be a calmag deficiency but just wanted another opinion. It's indoors in soil going on week 5 of flowering. I water about 2-3x a week feed-feed-water. I'm using Aurora innovation nutes...

Hey there guys, I need some advice. I can't, for the life of me, figure out what's wrong with my baby(white widow auto). It's the tips of leaves are yellowing and it looks like burns but doesn't look like any other picture I found on forums.So this is what I've done with it recently...

I’m growing outdoors in Australia. Flowering is due to start in a week or 2, I have a plant in a 100Litre pot, coco and potting mix, with a little pear moss and perlite. Fed every second water like all my other plants (which are fine). Temperatures have been quite warm the last couple weeks...

Hey everyone. I have used this site for my last 2 grows, but never needed to actually post anything because you guys always answer my questions via someone else's questions. That being said... I have this issue that most probably wouldn't consider a problem, nevertheless it's been driving me...

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...

New grower here looking for some advice... My plant is 3 weeks into veg now & was transplanted into Fox Farms soil in a Smart Pot three days ago. (Prior was in MG Organic Soil) After transplanting she also received her first feeding of nutrients. This leads me to think she's suffering from nute...

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...

noticed these spots on one of my babies, they are fed exactly like the others as well with phd water so i wanna rule out that, the o ly variables that i could think of that would be affecting it would be the time change as well as losing an hour lof light, changing temps in my area. they are im...

Is this a nutrient deficiency or A PH problem? Grown with fox farm soil in 3 gallon pots with distilled water.

This is my first grow and since the beginning they have been growing really slowly. I started them off around 12 weeks ago from a bag of mixed seeds of varying age (all seeds were collected from buds used over a few years). I selected the newish looking ones and germinated quite a few. These are...

I have a white widow auto which is 36 days old from sprouting out of the soil. Its only my second time growing and im just a student with a little setup in my own bedroom. It seems like the plant got some sort of deficiency. It started very slightly visible(about 2 weeks ago)but it has just...

So I've got three very healthy plants. The Durban Poison and Cherry Lime Haze are about 2 feet tall and the Kandy Kush is about 3 feet tall. I've recapped most of this in my other thread (https://www.rollitup.org/t/can-you-confirm-if-this-is-mag-deficiency.947387/) Here's info: Growing in...

One of my plants is starting to get some orange and brown spots. I was thinking it could be a calcium deficiency. These plants are auto so I have them half a dose of cal mag. It hasn't seem to have helped it yet. I was wondering if I should give them a full dose or if there's anything else to...
