I have these two plants in my mother chamber and Im not sure what is going on. Im using MG 5-5-5 and my ph is between 6.4-6.8.
Im using pro mix seedling soil. I gave them just distilled water for the first 2 weeks then a 1/2 dose maxicrop followed by a 5-5-5 dose of MG three days later. 3 days later just distilled water . A few days ago I checked on them and they looked like the photos below. Im using ph strips so I dont know how accurate my ph readings are. I let them completely dry out before watering again. I have them under cfls 24/7 room temps are 73-77. Humidity is around 30%.
A friend of mine said that since they were started from seed the lighting cause them to grow to fast for the roots to keep up, could that be?

Also I would like to stop using MG on all my plants and was thinking of FoxFarm of Pure blend anyone like these products? I would be using them on some bonsai mums.

The poor dears look thirsty! Especially with the very low humidity, a drink will cheer them up.
6.4 is very slightly too low.
Also, switch to tap water unless you have a compelling reason not to.
I like PureBlend Pro. It's a fairly forgiving nute and IMO better quality than the FoxFarm. There's a Botanicare product (TriFlex) that is equivalent to the FoxFarm if you want to go the cheap route with a 3-part nute. But I like the PureBlend Pro a lot. Bonus, it's loaded up with good organics that help buffer pH.

Thanks stinky, I have hard well water so distilled is what I can find other than natural spring water. I flushed them yesterday thinking salt build up and they have perked up a bit but not alot. I raised the humidity to around 50% hard to keep it higher. Are you talking about Botanicare Pureblend pro for soil 1.5-4-5 for veg or the original 1 â??0.5 â??1? In the mean time how often should I use 5-5-5 I was thinking every other to every 3rd watering?
