- Hard to tell Deanos mate, can you tell us more and send a lights off pic? what medium are you growing in and what are you feeding her? Ph, EC?6 months ago
- Ok sure and thanks! It’s pineapple chunk, grown in gold label soiless mix with full canna range nutritents, ph 5.8-6.2. Ec .7 - .8 my tap water ec is .15 and I’ve added cal mag to make it .35 when canna say to take it too .45 before adding nutes but as I use half of what they say with rest I thought I should also with that. They been flipped 12/12 for 20 days and have grown an extra 3ft in that time 🤦🏻♂️6 months ago
- sweet mate, definelty under feed then man, I use the same nuits, and have similar BG EC, im thinking at this stage, you're EC should be around 1.0-1.2, you're using canna and n b, with PK 13/14 now?6 months ago
- after the flip, the plant with exploded with growth, and need a lot of nitrogen, that's over now, and the growth will slow down, and your buds will grow, so less nitrogen is needed but more PKThey are dark, and have plenty of nitrogen in them by the look of things, I would go for 2ml PL of PK 13.14 and top the rest of the EC up with the A n B, to around 1.2, does that work? That way, the get more pk, and less nitrogen so the will lighten up a little, and the buds will be denser in the long run6 months ago
- ah ok. Yeah using cannazym, canna bloom, boost and just been waiting to start the pk and then I noticed this and it kinda stopped me in my tracks as I thought I might be over doing it. Only my second ever attempt at growing and last time was blue cheese and that stuff is a dream to grow in comparison 😂 thanks for taking the time to read and reply 👍6 months ago
- @deanos Blue cheese mate!! Perfect strain for new growers, one of my favourites 🙂 And your welcome man. Happy to help, you're doing the right thing by taking it lightly with the nuits, always better to under feed than over feed 😉 Thanks for signing up too, welcome to Percys mate6 months ago

- So as an outdoor grower, I have some plants into new ground but made the mistake of not testing my soil first. Everything seems to be going great EXCEPT all the plants have yellowed in the center of every new growth, I mean banana yellow where the rest of the plant looks healthy. At first I thought maybe it was something I added to the soil, but some of these plants have had nothing added and show the same problem. I have flushed them with water tested at 7ph. and added iron chelating, this seems to have helped a tremendous amount. But there are still a couple that are struggling, after taking a soil sample and flushing, the ph level of that sample tested at 8 PH. Just wondering if there are any other tips you might have to correct this problem. Maybe I`m off thinking a PH issue? Cheers and thanks in advance.7 months ago
- I like my plants at 6ph tops. I’ll let one of the pros tell you about what you may be lacking in nutrients yellow sounds like nitro def or a stunted plant. I call them zombie clones because they will stay alive and flower but never grow because of acidic soil they were started in. All my clones I start in the ground with a high phosphorus drink to help establish the roots for the first 3 weeks. Also dump a half gallon of milk per plant for the calcium which helps with nutrient uptake. Try this for a quick possible fix.7 months ago
- How it going Phil, good to see you mate..... itll be so much easier to diagnose this if you send us a pic mate. Yellow leaves can be cause by many things, see the yellowing will help tell us what is causing it7 months ago
- thanks for the replies, figured it out. Had nothing to do with ph. Neighbour sprayed when he said he wasn`t going to, chemical burn. Half my crop toast. fortunately I had enough clones held back and will be planting in a different location.7 months ago

- I think most are growing out of it, maybe an early pruning will encourage them. Was nice to see some new growth happening, hard to bury the neighbour when they are related ... lol7 months ago
- I’ve had ph problems for months. Zombie clones, funny but true. Seen many poor stunted plants. Still got something out them though. So here I am trying this put up an image. I’m sure macky can let me know where I’ve gone wrong 🤔Chocolate haze cutting. Just been flushed as very dark but coming along. Excuse the lights 😎7 months ago

- The symptoms of over watering a cannabis plant will display for a number of reasons. The roots need water and air in order to uptake nutrients. If you water the plants too much, your plants will not be able to absorb these things effectively. However, cannabis plants grown in hydroponics, do not usually suffer from symptoms of over watering. This is because the roots have more access to air, via an airstone. Using an air stone will allow plenty of air can get to the roots. If your plant is showing symptoms of over watering, in hydro, there may be an issue with your air stone. You should check for blockage, that are preventing air goetting to the roots. If you over water your cannabis plant, the bacteria in the root zone will also not be able to breathe. This will cause a rise in bad bacteria, which will bring on root rot. On the other hand, if you do not water your cannabis plants enough, the medium will become too dry, and good bacteria will die and not be able to live in it. It is a fine balance, which takes practise to get right. If you have any questions about fixing an over watered cannabis plant, then feel free to ask for help in our cannabis growers forum Symptoms of O verwatering Watering in Soil Most cases of over watering, will be with plants grown in soil. Soil retains water for a lot longer than coco, so less air can get to the roots. If you do not let the soil dry out between watering, the roots can't breathe. Symptoms of Over Watering Cannabis Plants If your leaves constantly seem plump, and full of moisture, you're probably over watering. The leaves are absorbing more water than they can sweat out. They become heavy, and will droop and curl under. Over watering your cannabis plants will have an effect on their whole nutrient uptake. Your plants growth will be diminished, and your plants are prone to getting mould and rot. You also run the risk of having bugs move into your grow room. Insects larvae like moist mediums. If your soil never dries out, bugs will move in. How to Avoid Over Watering To avoid over watering a cannabis plant in soil, you have to let the medium dry out in between watering/ feeding. There a 2 things you should check before you water you weed plants in soil. Firstly, the top 2 inches of the medium should feel dry when you put your finger in there. Secondly, pot should feel light, and the medium should look dry. There is a fine balance you have to find, which is specific for each grow, it will take practise on your part to get it right. Don't let the medium completely dry out, as this will affect the microbes living in the soil. Keep checking the weight of the pots, if you can lift it easily, water them. If you can't, and it feels like there is weight to it, do not water them. If you get run off after watering, remove it. Do not let your plants sit in wastewater as this will also cause over watering too. Remove run off immediately after feeding/ watering your plants. Symptoms of Over Watering a Cannabis Plant in Coco It is very difficult to over water when growing in coco. The coco doesn't hold as much water as soil does. It runs straight through just making the medium damp. You can water every day in coco, and still not suffer from over watering. If your plants show the symptoms of over watering, then you are most likely letting your plants sit in run off. This will also prevent air getting to the roots. Water you coco everyday, but always make sure you remove run off to prevent salt build up, and root rot. With practise you will be able to find the right watering and feeding schedule for your cannabis plants. If you continue to have issues, after fixing your watering schedule, then the problem may lay elsewhere. Thanks for reading!
