HELP! Whats wrong with my Plant? Hey, fellow growers! I need your help! I'm having some issues with fertilizers while cultivating this incredible strain, and I have no clue what to do! I've been using Advanced Nutrients fertilizers as recommended, but something's not right. My plants are showing some strange symptoms, and I can't tell if it's nutrient overload or deficiency. I'm a bit lost here! Here are some problems I've noticed:The leaves are turning yellow or brown. Some leaves are curling or wilting. Flower development seems stunted or abnormal. Flower production is low, and the buds aren't forming properly. I…

Hi every, I'm new to the forums and I'm also a first time grower, my plants have been doing rather well so far, but I have come across a few (issues?) With the plant as it has started to flower, some of the leaves on 1 of the 2 plants has what looks like very minor tip burn, and both plants have very bright almost fluro green/yellowish new growth, and also some purple stems. Both plants are auto gsc, I was hoping I could get some opinions, thanks in advance.

Hi all, what are the spots on my leaves? They occured on one plant and only on a couple leaves. It came up after I changed nutes brand (from a bunnings brand to a GH tri-part). PH 5.8 to 6.3, ppm about 800. After the first drink I added calmag to the mix but still showing. Growing in coco, indoor under Spider Farmer SF2000. Thanks.

Hi fellow growers, This is my first post here so please direct me if I am in the wrong place or make any mistakes. I decided to start growing at home this year and so far have not had good results. Some background - i grow in coco in my greenhouse and germinate my seeds in peat pellets I bought from Bunnings. I am using auto flower seeds bought from seed city. The seeds germinate well and push through in about a week. I then transfer them to pots, I just remove the webbing from the peat pellets and put them straight into the coco. After a week or 2 of good growth it all goes pare shaped. The plants stop growing upwards and outwards, then after a few more …

Outdoor grow, a couple branches are shrivelling! And crispy. The rest of her is fine but afraid it will take over the whole plant. Its probably just about to go into flower. I don't know if this is a deficiency of some kind or a disease? Any help appreciated, cheers.

Trying canna terra for the first time, mixed a little extra perlite into the mixture and planted seeds straight into 10 litre pots. The plants are 5 weeks old and 3.5 weeks old and I'm super happy with how much they've already grown. But the plants have been a bit of a lighter green than usual so I gave them a feed of green powerfeed about a week ago. Now the 3.5 week old plant has started shooting out real yellow looking leaves. Could this be fixed with an iron supplement? 5 week old plant 3 week old plant 3 week old plant with possible iron deficiency?

Hi all. I hope you had a great Christmas and looking forward to a better new year! I changed my fertiliser awhile ago from Ozi Magic, to Growtek. Now I'm not bagging any product only my own growing practices. Why did I change? hey, who knows but I felt like I needed more humph in the grows. They were a little slow and I know they could do better. Anyway a lot of my plants leaves started to yellow and fall - lower and fan leaves first, became very soft and limp. My watering practice had not changed and ph always tested between 6.3 - 6.6 there about. Anyway I went to the hydro store and they suggested this product. I have used it once and I found it helped, well the …

Hi! This is my first indoor grow and so far its been OK. I'm at Week 5 of flower now and the lower, older fans are showing signs of nute deficiency or excess. I'm growing in Canna Terra professional and been feeding it bloom nutes with some boosters for Vit-B and potassium/phosphorus I feed every 3-4 days, temperature seems fine between 20-25c, ventilation with exhaust and oscilating fan, PH on the run off water is 6.3. Is this deficiency or excess? Looks like something with potassium from other photos online...Am I correct or is it something else? Also, what can I do to fix it? The other leaves on top look fine and the buds are looking quite healthy. THANKS!

Hi everyone My cannabis plants are showing yellowing/pale leaves towards the bottom of the plants. I'm 3.5 weeks into flower, is this normal? If not what can I do to fix it? I haven't PH'd my nutrients or water in the last month. I'm also using Green Planet nutrient set which includes GP3 Grow, GP3 Bloom, GP3 Micro - plus I bought GP3 Massive. I've been following their nutrient guideline this whole time and its been good till a week or so ago. For my soil I'm using Coco coir premixed with 30% perlite and Canna Terra Professional. I mixed these two together and added a 50lt bag of perlite to the mix. I've attached a picture if anyone can help. Sent from my C…

Hey guys Sorry for the double posting, I’ve been struggling with my first grow. I am 100% stressing out about how these babies are going. We have been using the grow candy nutrients, they are on 18/6 schedule, but they seem to be struggling. Can someone please point me in the right direction? I think I’m definitely going to just do feminised next time instead of autos, because the more I read the more people advise against them with beginners. We have only just purchased an ec reader off eBay and a digital ph meter so we can be more precise. Me and my partner are constantly fighting about different shades of yellow and green haha. We don’t actually know what we are meant…

Hey crew I’ve just re jigged my grow room so been a bit quiet, took time to set up etc . I’ve just got some AK clones off a mate and I only got them a couple days ago and they have yellowing and rust spots on the leaves . They are in coco in small pots which I’ve now moved into 50L pots with coco/perlite mix with diamataceous earth mix on top to stop fungus gnats . I’m using GRowth Technology nutes A and B with silica , I’ve added some cal mag just incase today but any idea what it’s missing or what I should do ?

For some reason, every time i find a decent nutrient problem solver, they dont have pics and when they do have images, they disapear after a week or 2 so now while i have one up, im downloading all the images, copying the text and making a copy for OzStoners so i hope you all find it helpfull or atleast an interesting read :smoke OverGrow thread i got this all from Considering most growers these days use 2 or 3 part nutrients, most of these problems shouldn't appear...more than likely the problem will be a pH imbalance which can result in the plant showing problems that you can easily confuse with with other problems or deficiences. So i found 2 pH charts that ar…

WOndering if anyone can give me a rundown on EC for growing in Coco or point me to a site which explains it in simple terms for a simple bloke! I'm mixing prescribed nutes in rainwater from specs on bottles and am getting an EC of 2.0-2.2. (in the can, not measured the run off as i'm not soaking pots. Plants are small.) Does this mean I adjust the nute quantity to change the EC or try and change the water PH prior to the mix? I've got no fucking idea. Cheers
