Help do you know what is wrong with my plants?

[WeedintheHI]

Aloha,

Thanks for taking the time to possibly help me with my babies. I am a first time grower and I cant figure out what is wrong with my plants. PLEASE HELP!!

INFO: 400W, 20 on, 4 off. 6.5 PH, 3 fans air in and out. 3 Gallon soil pots, 5 weeks old grown from seeds, blueberry sativa. Mist every other day. Water every 3 days. TEMP 81 Humidity 65-70 Currently not adding any fertilizer or nutes.

Problem: About a week ago we started to see some yellowish spots on the leaves. They start at the bottom and work their way up. Two plants now have 4-5 leaves with spots. Please see attached pictures. After doing some research via the web we thought it may be a lack of Magniesum, Some of the other plants had leaves folding in. We sprayed with epsom salt water this seemed to help them. ??? We check leaves daily for bugs other problems but they look good. Why do I have yellow spots?? I have attached two pics hope this helps!!

Mahalo friends for your help!!

[WeedintheHI]

We are using tap water that we let sit out for 24hrs.

I dont think its the soil because the spots are only on two plants? If it was wouldn't all my plants have spots?

Anybody???

I have a strong idea on two or three issues you need to work on, but we usually don't offer guesswork when diagnosing plant problems.
As previously suggested, copy and paste the troubleshooting form here...fill it out as best you can, and we'll get right on it. The more information you can provide, the more accurate the diagnosis is likely to be.

Anybody???

Again, fill out the troubleshooting form. Much of the information you have been given I agree with......the pots are too large, the plants look over watered or under watered..... Thus the need for smaller pots at first....the water goes way down and the upper part stays dry then the roots reach into the wet and the plant gets sick, like I think we see here.

So, fill out the form and give as much information as you can, what you have given is not enough for good assessment, it is all guess on the part of all of us.
Thanks!
