Hello again, now I have a bigger problem not sure how this happened but
it did. My female SD is suffering from nitro toxicity. Not sure how or
why. I’ve been watering it every other day with half a gallon of water. I
think where I messed up was that I’ve been using a filtered water
source that has zero ppm. I’m not sure what my soil ph is. I’m a new
grower so needless to say I don’t know shit. But what I do know is, my
leaves are turning yellow from the bottom of the plant to the top. They
are also dark green and crispy. Not only that, the fan leaves are
dropping like veterans with ptsd after a kid lights a fire cracker! I’ve
been trying my best to take care of this little brat but she isn’t
cooperating with me at all. I haven’t added any nutes to the soil or
anything. Just watering. Uhg. I need help. Let’s see, what else? Oh! I’m
not sure what kind of soil this guy is working with and I’m sure that
could be a problem for me to correct this. I see little white rocks
mixed in with the soil and I just pray that this guy didn’t use miracle
grow for fucks sake! I’m frustrated. He gave me this huge plant in veg
state. It was looking good until about two and a half weeks ago when I
started noticing the leaves going dead on me. Now it’s in the beginning
stages of flowering and it goes to shit in a snap. Please help me.
What is the strain and type(unknown bag seed, strain name, regular seeds, feminized seeds, auto-flower, etc)?
Indoor or Outdoor? If outdoor, planted in ground or in a container?
Size of space (max height and area, length/width)?
Soil or Hydro? Type of Medium used? System type?
pH? Of the soil or medium (root zone/reservoir/run-off) and of the water and/or nutrient mix that is fed to the plant?
Type and strength of nutrients used? NPK? EC/TDS/PPM levels? Of what you feed it as well as what is in the water by itself and in the soil/medium (run-off), or reservoir.
Temperature? Day vs. night temp or highest and lowest temps? Root zone temps?
Number “weeks/days” from into Season, Vegetative Growth or Bloom/flowering?
Add anything else you feel would help us give you a most informed answer. Feel free to elaborate, but try to be brief and to the point. Short and to the point questions and/or facts will help us help you
absolutely need to get Ph of run off and a ph of the water you are using some pictures would be useful as well buy a cheap ph test even the paper strips you will also need ph up or down based on ph of both tests since you will need most likely to flush your soil with a correctly ph’d water
First, despite the crazy misleading information elsewhere on the internet, Miracle Gro is not necessarily a bad plant food for cannabis, you just need to be using an appropriate one for cannabis, for example, their tomato plant food can be used with great results, again if used properly. And Robert and I both have mentioned using Miracle Gro on occasion elsewhere.
Also, the little white rocks are probably just perlite, and this is usually a very good amendment to most soils or soil like growing media, it helps with aeration of the soil and better drainage.
Sour Diesel
Indoor with soil not sure what kind
Fluorescent light, not bright enough
Not sure what kind of soil
Not sure how big my smart pot is but it looks to be 1 3/4 foot across and about a foot in depth
Not sure what the ph is of soil but I’ve been using water that is 0ppm. Our tap water here in seattle is about 41ppm Ive been filtering it because I thought it would be better for the plant
No nutes used as of yet but I just bought some.
I’m not sure how long it’s been in flowering either, maybe 3-4 weeks no more than 5 weeks into flowering.
Temp stays at 75 all day long.
You said you weren’t sure what kind of “soil” the plants have? Are you sure it is soil? It could be a soil-less mix, this could look like “normal” soil to the untrained and unfamiliar eye, however it is very commonly used, and if so, 0ppm water might not be the best choice. A soil-less mix that is nearly entirely peat and perlite only, if 0ppm water is used, it can get very acidic very easily, and in fact it is recommended to use water that has nearly 150ppm in calcium carbonate to help stabilize pH. Also, if it is soil-less, then the pH needed will be different than soil.
Since you are not feeding it, and have only been giving it 0 ppm water, it is probably not a nitrogen toxicity.
Hey MacG! You were right! Ding ding ding winner winner chicken dinner! Nah but for real. I didn’t read this until just now and since I’ve read this I had already fed my girl a lil bit of nutes to see if it would help or hurt. It helped. I’m going to water in about 3-4 days and then give her the full amount of nutes which is about 2oz. I have her in soil. It’s organic. I use a organic nute as well thats 4-3-6… I guess the SD strain is a greedy fat bitch who enjoys a buffet line… So I’m gunna feed her carefully because I know it’s easy to over feed. She was all leaning over for a minute but the next morning after I fed her she was all perked up. That was this morning. When I turned on the light she was happy as a clam, she perked right up. She woke up like a kid after mom comes in a flicks the lights up on a dark room. It was cool. Nevertheless… I could’ve prevented this. I lost a shit ton of fan leaves that I won’t ever get back. Sad. But the truth. After I crop this girl, my next project is GSC… I will post some pics when I can. Unfortunately I don’t have any before nutes pics. But the leaf burn is still visible.
Thanks for everyone’s help. You guys really know your stuff.
JUST WHEN I THINK I HAVE DONE SOMETHING RIGHT AND SOLVED A PROBLEM HERE COMES ANOTHER PROBLEM RIGHT BEHIND IT TO SMITE ME!
I mean damn, this broad is temperamental! Real sensitive just like every human female I know!
Anyways, looks like I f@#$ed up again. Damn! Ughh! Ok so last night right before I put my sour diesel girl to bed I decided to give her a half gallon of water with a teaspoon of nutes. Before I did that I noticed that the top of the plant has a few leaves that are twisting and shit?! So I checked to see how my moisture was doing by feeling the bottom of my smart pot and granted it was moist yes but not soaked or wet. Maybe slightly but not much considering its a 20gal and I watered about two to three days ago. After I water and turn off my 1000w HPS that was hanging a little over a mans forearm length above the plant, I noticed that some of the stems had a dark reddish tint on the top but not at the bottom of their stems. I inspected the plant thoroughly and throughout the entire plant to see if ALL the stems had this issue and to my eyes I saw only the upper stems towards the very top of my plant have this particular ?problem? I’m not sure why this is, so I had to do a search and from comparing the symptoms it sounds like I may have had the light too close??? Although I’m not sure if this diagnosis is has been properly assessed, it is from my understanding after reading about these symptoms that this could be a few things besides the light burning my baby. It could be a nutrient problem as well or exclusively. The leaf twist is really alarming so as of now I lifted the light about two feet away from her just incase it is a case of light burning. This plant is so damn sensitive and I know all cannabis plants are but sour diesel in particular is a tough challenge for a first time grower. Anyways here are some pics. I did my best with the light on so I will post more pics tonight when I turn the light off, please help guys I don’t want to kill this plant. It’s not mine and even though it’s not mine IVE grown attached to her. I’ve had her for a while now and it would literally hurt my feelings if I killed her. This is the first time I’ve had any problems with her since I got her months ago she was cool, now it’s a love hate relationship we got goin now. Reminds me of my ex! LMAO
You are in flower right? your plants nutrient needs are fairly high in flower but I would say the light being too close was likely part of the issue or main cause. I am growing purple kush atm and their tops start to get their colour around 3-4 weeks in flower though if your discolouring continues add Cal-mag to your feeding and double check your run off ph may also be start of a def.
dig some soil out close to the roots add water ph’d or what you have been using enough to totaly saturate that soil and basically let the muddy water settle until almost clear then test it’s ph get back with the number and we can run through likely issues.
this is how you test your soil ph in root zone since you may have to make adjustments I am not suggesting actual run off test as this involves watering and measuring water that comes out the bottom into your tray. That would do same thing but you may not want to water at this moment and it takes time for soil to dry again
Hey Dude. Remember when you are using Demineralised water(0 PPM) that if u do not add the right nutrients to the water, this will really dehydrate your plants and you will get same problems as if you were underwatering your plants. Make sure to add the right nutrients and pH your water to 6,5 with the right acid for either bloom or vegetative phase. If you do this, you will not run into any pH problems. Although remember to only use your nutrients when your plants give small indicators of different deficiency’s or when you switch from veg → Bloom.
Your last photos are 100% deficiency’s check this out and do them one by one. When you are flowering you need a continuing increase of nutrients BUT u still have to look out for nitrogen toxicity and your plants look like they need calcium and some need phosphorus but start out with this homepage
