Over Watering?

Hey all I am still fairly new at this so I am asking for a little help please. Can anyone tell me if this is over watering or something else. These 1st two pics is the plant I am concerned about. It is a 2 week old clone. As you can see (hopefully) the tips are brown and the color is bright green.



These next 2 pics is of another clone that is about 2 weeks old. Same soil conditions and lighting. These seem to me to be quite a bit healthier and a nice dark green.



Please anyone help me with this.

I forgot to add that the clones are from the same mum and started at the same time. The white you see is a layer of sand to keep the gnats in control (works great).

could you tell us a little bit about some factors of your grow?
growing medium is soil or a soil-less? which brand or if your own mix, what are the components?
all four i think are the same strain if i read your journal correctly, could you confirm that please?
if you've started feeding them, are you top dressing or using teas? which brand? also, whats your feeding schedule?
whats the relative humidity and temps?
i imagine you're watering all the pots with consistent amounts of water, all at once. the plants in general actually like drying out, this aids in stimulating the roots to go traveling for water which builds a bigger root ball. so if you're not letting them dry out properly then go ahead and start doing so. it won't hurt the existing problem and it's one thing we can scratch off the list as a possible problem.

the growing medium is soil, pro mix. there are actually only two clones there just 2 pics of both of them. as of yet I have not fed them anything. I thought it was best to wait a bit before feeding new clones, not real sure about that tho. I do try to let them dry out before watering but I must admit that the sand can throw me off. I do use ph balanced water at 6.5 ph. to be honest I don't know what you mean by top dressing and I haven't used any teas. I am in the process of creating a compost pile. The temps in this closet run at 25 degrees Celsius. The humidity runs around 55%. I hope this helps your diagnosis

I think they are okay, if it gets much worse then be concerned. I think sometimes in order to produce roots, the plats take a little nutrients from the leaves.

amen to your sig OldGrowth420. I hope you are right about my little lady. Will watch and see and put a check on watering. Might go with a 1/8 solution of nutes as well. I don't grow organically as this is really my second grow that is showing signs of success. want my ladies to blossom you know

First, if you're just starting a compost pile, don't plan on using it this season.
Second, how long have your clones been in the soil-ie: do they have a good root system yet?
They look awful light like they are hungry, and I'm not familiar with it, but doesn't Pro Mix have enough goodies in it to sustain a plant for a couple weeks? Did the leaves start turning light all at the same time?

It seems that pro mix really doesn't have any extra nutes in it. They do recommend that you start feeding your plants around the 3 week mark. The clones are just about 2 weeks old so I think they have a good root system started. The leaves did all turn at the same time. Yea my compost won't be ready til next summer, I will start it in the spring. I have worked in commercial composting for about six years now and I hope I can take that and scale it down for my backyard. I can get the compost cooked in 60 days so about my 4th grow I will have some ready. If my system works I will post what I did.

promix isn't actually soil. it's a soil-less medium and it's without any nutrients. you will want to start them on a nutrient feeding schedule soon because they will starve in promix. guano teas are usually great, pick a guano for now that has high nitrogen. you'll have ratios/direction on the package on how to mix a full strength tea, first feed them at 1/4 strengh and slowly work your way up to full strength. your schedule might look something like this: feed them 1/4 strength nutes on monday, water them pure water on wednesday or thursday, pure water again on friday or saturday. feed 1/2 strenth nutes on monday-repeat as first week until you're at full strength in about a month.
keep in mind you might have to water them every day or only once a week depending on your grow setup, your locations enviroment i.e. r/h and temp, and then of course the strain you're working with.

cool thanks AK. I hope I can find some guano here so I can avoid the shipping fees. I will for sure use your advice. Thanks to all that gave me some great advice.

Something is off balance on these.

With the sand, you want to use the stuff you sweep in between bricks for landscaping, you water it, and then you let it dry and it will get hard. You have to completely seal the whole surface for a few days to stop the breeding cycle. But after that, you DO want to remove the sand, however, it comes off in solid 'slices'.

Likely, you're suffocating the plants, they all show the same symptoms.
