fan leaves turned yellow and are dieing all over night.

Hey all. Okay, so here's the problem. I have 3 four week old plants. Yesterday I watered them around 3pm, and then later I decided to top them all, I cut right above the 4th true node. I know there can be a lot of varibles. But, I'm using MG moisture controll soil, I have just under 300 true watts of cfl's. Ummmmm, I think that's it. Feel free to ask any question at all. Thanks in advance! =)

Some have had problems with that soil. What size pots are they? Pics are usually necessary for diagnosis.

They are in 1 gallon pots,you think it might be nut. Burn?? and I will get pics up asap! I have company over, otherwise I would do it now. And thanks for the quick reply! =)

mg moisture control did the same thing to me. i bet its ur problem i would try and get them in some good dirt quick

No, not nutrient burn. All of the fan leaves yellowing overnight, especially right after watering, often means root binding. You have to check the roots asap. Lightly squeeze the sides of the pot a few times to loosen the soil. Tilt the plant, grab the base of the stem with one hand and the pot with the other and separate, sliding your hand along under the soil to support the root ball as the pot comes off. If the roots are swirling many times around the bottom with many others getting bunched up, you have to transplant immediately for any chance to save them. Once root binding progresses to serious, it can kill the plant even after transplanting.

It's still just a theory so while you should check quickly, don't start worrying just yet

Blah, I was trying to get off with being lazy *and cheaper* by using the MG moisture control, but I guess it mite have back fired huh? Lol. And mothers finest, I will defitnally check if the roots are balling up in the bottom or anything tonight. Will also get pics up as soon as possible. Most likely in a couple hours.

good soil is just as cheap. id start over if i was you (dont mean to sound mean).

Well, these were just my test plants I have been growing just while my attitude seeds got here and to get everything ready before the good seeds got here. Which got here today =), fem. White widow, and some pyramid freebies =p. Soooo, I may just scrap these, and get some fox farms??

fox farm can be hot for little ones...especially sativas. roots organic might be a little better, but its all opinion.
