Ok bro...theyre not lookin good but theres hope. I use nutes on my plants after theyre like ten days old. Low strength like 250 ppm to start and then increase it with time untill you hit around 1200. Just gauge when to raise them by the length of time you expect them to grow for. 70-90 days flowering for most strains plus however long youd like to veg. Stop raising ppms if they start to burn and raise them if the color starts fading to yellow. Tieing them down is great for small spaces, theyll recover. I dont know what type of light you have but im assuming its a cfl. If it is i hope that its not a small one, get a Y adapter and two 150 watt equivilent bulbs to put in each socket you have. They need to be really close to have good results, like 4 inches away and then just move them up when you plants get to close. If the lights are stuck where they are put somthing under them to get them close. Dont water w nutes every time, and wait till the pots feel light to water again. They dont like to be in a marshy environment, they like to dry out. Almost. They should be bigger but im sure its your first try so dont worry, youll do better next time. Theres a cheap 12 dollar ppm meter i got off amazon, its blue and it works fine. Get a big suringe from the hydro store and write down the amount of nutes in ml it takes to hit whatever ppm levels you want in a gallon or half gallon jug of water. Then life will get easier. Buy a baby bottle of super thrive for 7 bucks, they like that and cal mag. One drop per gallon or two or three of super thrive and one drop per litre of calmag. Mine like that. Top em so the side branches bush out and get taller, then tie those down also. I dont think id start flower yet but you might have already. If your lst them then you should be able to keep them going till they get bigger. Got string? Just dont tie them tight or youll choke the life out of them. Oh ya, when you get good at this and you "learn to roll", dont crap on peoples style on here, thats not what rollitups all about. Help people out, thats what im on here for, to learn, not to read arguments or someone saying start over. Good luck bro, have a rip for all the guys that said cut em down when they turn out good and laugh.
