This is my first grow. Grow Box, Co2 enhancer, moon dust nutes, lights 20/4, Seeds are Auto Creamy Caramel, 11days in. Put a bigger air stone only because little one that it came with box broke and it is the smallest our hydro store had. They are in 1 gallon water container. Leaves look a little light green and droopy. Any help would be greatly appreciated. Thanks Doug

Hi there. This is my first post and I hope it's in the right place. I have been given a baby to grow for personal use outdoors. I've never grown before. It was being cloned under an old 400w til it was about a ft tall, then handed on to me. I'm not sure what is up with it. I have read in many places that red stem could mean deficiencies in NPK but as it's a new plant to me, I let it adjust for a week before I gave it a half dose of both Miracle Grow and Seasol. The plant is in a 30L pot, with plenty of drainage. In a sunny spot, but as it's Spring, it's not overly hot atm... It's in good quality potting mix and this has been mixed with loam and well broken down chook …

Plants seem to be a light green, with a slight yellow tinge too it. Fed at 1.1ec. Went on the dutch master website, said I should be at 1.4ec. I want to veg for another 2 week's maybe 3, I'd like them double what they are now.

Hi guys, i seem to have a strain that loves to rip out nitrogen in late flower say around week 7. I really want to push these girls to 10 weeks but i think they wont last. Has anyone else had this experience with a strain? Im curious to see if there's something i can do for my next round. Ive added a nitrogen additive at week 7 at 0.5 ml per L. I think ill double that. Any ideas, solutions? Thanks

Having a bit of an issue with the EC in the nutrient solution for my recirculating through perlite setup. Nutrients I've been using are Canna flora 2 part with H&G multizyme and Canna PK 13/14, was using H&G 2 part up till a week or so into flowering. It's been going for a bit over 2 months, and I flushed the crap out of the perlite before first using it, had a small amount of PH climb initially, but that has stopped ages ago. Have been tending to run an EC of around 2.0-2.2 generally, but have had a couple of accidentally higher solutions, up to 2.8 once, but the 2 plants seemed to be loving the high EC and didn't suffer any problems from the couple of higher…

I thought my plants were hungry so upped their nutes and noticed them starting to burn. I checked the pH of the water in the trays and it had risen from around 5.8 to 6.5 - 7.0. I'm using pH drops so I'm not 100% certain but those numbers would be really close. Today I flushed the plants with a little bit of super low pH water to even out the high pH in the perlite and then gave them all a ton of water pH adjusted to around 5.7 and made sure that the run off measured exactly the same before putting them back in the tent and giving them all a feed. I checked the water before giving it to them and it measured 0.6 EC and around 5.7 pH and after giving all the plants a fe…

Hey guys, looks like I've hit a road block. Done a lot of searching and still got really get a straight answer. Some say P is low, some say N is low, some say the salts are too high, some say it is normal.... Who is right? Basically the plants were doing fine in the DWC until about a week ago when a few nute problems started to appear. It was yellowing veins in the leaves, this has now spread over 2 plants and I'm thinking they may need to bed pulled or will die. Indoor/Outdoor: Indoor Growing Medium: Clay balls Growing Style: DWC Watering/Feeding Frequency: DWC stuff Nutrient Strength (PPM/EC): 1.8 PH Levels: 5.8 Temperature/Humidity Levels: 40% H Water temp 23.3'…
