Definitely a controversial topic.....here is a controversial answer. Scrap your ec meter and don't rely on it to feed your plants. Start your grow with 1/4 recommended manufacturers dose and increase it to half around the end of week 2. Keep it there and monitor your plants leaves to see what they are telling you. If they get really light colored then they are wanting more food. If they get really glossy and dark colored then they are getting too much feed. In my opinion it is much better to monitor your leaves and learn to read what they are telling you than to rely on an ec meter. Different plants in different environments will require different amounts of nutrients so relying on a certain ec number can cause you issues. Learning to read your plants leaves will give more successful grows than shooting for a certain ec.

Hi @Uk420show aluminum paper does not work, you have to use white plasticized or mylar paper, you can find it at any DIY store for sale. The light from your light source when reflecting on the aluminum foil will create points of heat that will burn and damage your plant. if you are not going to have an air extractor, you should have an extra fan for air circulation and a dehumidifier because without an air extractor you will have high humidity during flowering. for grows without air extraction there is a good solution, 1 or 2 natural bags of CO2, you will find them for sale in any grow shop are a good help for those who plant without air circulation. good luck mate 👍🙏

Morning m8, 1st thing to do, check your ph range. If it's ok, you should up a bit your nuts (need for cal/mag).

your highly unlikely to get root rot with an active system like a bubbler roots do discolour over time is the dark bit mushy consistency of egg yolk if it is pick it out an clean around don't know of any treatment for roots someone will probably know

Hi If your netting is independently strung from the pot then there should be no problem have string all over the place on my plants tying them up down and around, just pending there needs

EC of 1.9 seems quite high to me, especially if they have already finished their stretching (usually during bloom you go down with the amount of feeding). Since you're in DWC, that should be quite easy to measure though (that's what i like about it.). What was the EC that you put in? What's the DC after a day? Did it go up? If so you're overfeeding (or there is a lot of evaporation). If it goes down, you should be feeding more.. if it stays the same, it's good. Measuring EC is the only way to know what works for YOUR environment. Following what the manufacturer say, is like following a dog-food manufacturers advice of 'give one can daily to your dog' without knowing whether you own a chihuaha or a rottweiler. ;) In my bonsai grow, if i go higher than 1.4 i get lightly burnt tips, so i know i have to stay below, but that's only under a 50W COB (wall drawn 50 watts.. not marketing 50 watts), and that was also during vegging. Did you measure the PH? In the past i had similar behavior (on my chili plants) when i didn't measure PH and EC daily, and didn't adjust it accordingly. I had PH drift, didn't catch it and then the plant couldn't uptake the nutrients correctly. DWC is in my opinion quite easy, but it requires a lot of measuring of EC and PH to ensure they stay happy.. i do it at least once a day.

if i open the picture up and "+" zoom in to certain spots and repeat.. the middle looks like ~50% clear? the rest looks pretty cloudy. however, it's not quite a good magnification, and image could easily fool. it's alarming not to see any amber if so much is opaque/cloude or seemingly so.
