Hi
@cannamazing! The good news is that your plants have developed massive root systems and they drink a lot. The bad news is that if you don't have a good runoff once every 2-3 weeks, nutrients may acculumate in your medium and roots will suffer from lack of air, lack of water, lack of space and salts buildup. At this stage it's too late to try a transplantation on autos, the only thing you can do is to increase your amount of water, at least once or twice before late flowering stage. This will allow all the root mass to drink, old [veg] nutrients will be flushed for good. Give them 5~6L, look at the runoff, and see how plants react after a day or two. This is not advised during late flowering, because of the impact on relative humidity and the risk of mold. Also, may I ask where's your coco from? Which brand? Looking at week 1, your coco looks like re-used one, with old roots..? I'm using BioBizz CocoMix and it's really light/airy/thin particles of coco, yours look more compact. Hope this will help, keep us updated and happy growing! 👊
