Possible nute burn?

Hi all, just joined the forums after lurking for a year or two. Too lazy to join;)

Anyway, ive been growing for a few years and have heard the bad rap on MG soil. So, I figured i'd give it a grow myself. Its been about 4 weeks and my plants (7 of them left) are about 7-8 inches tall. They were repotted once at about 3 inches, so overall theyve grown from seed to about a foot each. Recently ive noticed yellowing and drying on the tips of leaves, especially on the lower leaves.

I have not added any nutes except for whats in the MG soil (which was used as a test anyway). I didnt really care if they made it or not before, but they look more promising then any of my other indoor grows so id like to figure out how to save them:P

I'm thinking its nute burn? I cant honestly say ive had ANY probems growing before besides heat stress. Im not sure how to treat this specific case..and not sure if my ladies can make a full recovery, or if it will only get worse. Mind you, the leaves have just started with the yellowing and browning/ crisping.

BTW: Good watering schedule, good air circulation, 400W MH (veg), 5 gallon buckets, and again no added nutes.

Any suggestions? And pics:

Whole-plant pics are always helpful and actually are necessary to diagnose nute burn. That said, it doesn't sound like nutrient burn. Start by checking the lowest, oldest leaves. Check the podbuster leaves, as well as the one- and three-bladed leaves that first grew in. If there's nutrient burn, those will have been hit first.

If it's not, you'll need to get them some all-around fertilizer asap.

He's right that the plants look overwatered, whether or not they are, but it's probably a separate issue from the yellowing. At least the top third of the soil should be bone dry before watering again and healthy plants can survive all of the soil drying out completely for some time.

Alright, so I woke up today and they seem to have gotten worse.

Humidity at 50-60%

Brown spotting and crispness on all leaves. Yellow and even some copper discoloration. (Like my second picture in the first post)

You say its moisture stress....I can stop watering and let them dry but any solutions for the crispness and yellowing/brown spots on leaves?

Look for corrections in stabilzed new growth once a corrected watering
Schedule is maintained. Your damaged leaves are damaged but your plant
Isnt dead. Once the plants metabolism is regulated you'll be fine.

Alright so basically just wait it out? Shame..they were doing fine until a few days ago. I left town for about 3 days and watered perhaps a little too much before and after the trip.

And the only problem I have with waiting it out is: What if it isnt just overwatering? Should I change the soil (although I AM just testing the soil, anyway)? It would suck to stop watering them while they arent very healthy, only to have them completely die from all the stress.

Checked the pH level of the water I use to fee and it was 8.2!!

Re adjusted and re-watered the plants (soil was dry to about 4 inches). Runoff water was pH 6.2-6.5.

I also noticed while probing in the dirt lots of roots. Initially I didnt really care for this grow, so I planted the remaining 7 plants in 4 containers. At the bottom of the pots are a few root tips beginning to stick out. Should I transplant yet again?

Looks like no one is showing any interest here..but to those having similiar problems it turned out to be the pH.

Plants are looking much healthier and very perky/dark. Yellowing has stopped also.

I will post pics if anyone is interested..but again it looks like no one cares so ;)
