I have some Train wreck clones I got from a friend and started them about 8 days ago. They are starting to produce roots which can be seen near the top of the rock wool cube, but none protruding out. They are starting to yellow and a few of the leaves have a few brown spots. I have them under a 400W MH bulb about 3 or so feet from the top of the humidity dome. (I have a T5 but the ambient temp in the room is about 60 degrees, under the MH bulb its around 75 inside the dome+tray) I have been watering with PH'd water mostly but I did use light nutes about 3 days ago, which when I checked on them the next day I noticed yellowing so I started giving them just plain water. I also have seedlings in the tray which are looking completely fine and healthy. I am a newbie grower but have done a few grow attempts before but didn't have the money for the right equipment, I have also done A LOT of research and now have the proper equipment. From what I've read yellowing is normal in clones, its the brownish spots that I'm worried about. Any help would be greatly appreciated!
Clones like it humid but they don't like to be actually wet.. Put enough water in the bottom of the tray to keep it covered.. Open your dome a couple times a day to let fresh air in.. They like to be warm but not so much light.. I use a seedling heat mat with a thermostat as my cloner sits in an unheated garage and needs the additional warmth.. You can mist the tray and the inside of the dome if needed but don't spray the plants.. You want the dome to be 80 to 100 % humidity the first 2 weeks.. Once you have roots showing you can gradually wean them down to lower humidity around 70%.. Takes me about 3 weeks from cutting to rooted enough to exit the cloner..
Too wet bro you are way to wet, cubes should be damp not soaking wet good chance lower roots may have rotted dry the cube up a little make sure you have warm temps for roots, maybe a heat pad want those temps mid 70's. Don't let cube get completely dry that will kill her but you can't have it soaking wet when, they need I typically dip just the bottom of cube hold it upside down for about 3 seconds and put it back. One thing you can try to repair is if you have a disc airstone or one with a big surface area like that put cubes on it and get some air going through their I know for a fact this will help. G
Brass is correct at least thats how I did it back in 1975-1995 ....now its the Rumples clones or bubble bucket I use, and up and running in 10 days too ...fun did I say fun ....its fun http://forum.grasscity.com/do-yourself/121335-lets-build-bubble-bucket-step-step.html avoid buying the bubbler build it at all costs...see its a very cloning personal thing ...lol
