New Grower URGENT PLEASE HELP

[NoobGr0wer]

hey guys,

So I’m not 100% sure if I’m posting this in the right place, but please let me know if I’m not.

I’m new to growing, and gardening of any sort, in fact I’m even new to forums.

This is my first grow, super skunk auto from Sensi Seeds, under a mars hydro 300 LED, in soil by ganeco.

I’m very concerned that the soil in my pots is showing signs of mould, but hoping you guys can advise me more accordingly, I’ll try attach as many pictures as I can.

The plants have not been watered since Thursday night as they have been checked regularly, and felt moist, using the finger test
, and also quite heavy using the lift test. So due to concern of overwatering I’ve left without water.

Today I’ve got home from work, and I’ve noticed a white powdery residue on top of the soil, all plants look fine except 1 has some kind of 1 residue or specks on its leaves, this may be nothing, like I don’t have any other plants health or otherwise to compare too.

In the picture with me holding some soil in my hand the big white bit is a piece of perlite I beleive but you can see the white residue on the soil itself more clearly.

Please get back to me soon as I was intending on watering tonight, but not I’m unsure, 4 out of 5 plants do now feel lighter than previously, and also are dry a buckle deep.

Please see the pictures attached and get back to me ASAP!

Thanks. in advance guys!

Ps lots of pics in the same angle to try get best visibility of the white residue.

I did try take the plant out for clearer lighting, but if any more pics required just ask!

Just to add we are on day 15 of grow!

I forgot to add, please tell me what to do, and how I should proceed going forward!

So first off what I can see in the pictures of your plants they look healthy. It wouldn't hurt to get a close-up a cup of a couple of the leaves that look like they might have some spotting of some sort.

As far as your soil goes I can't really see the white powder you're talking about or the mold. I get the idea that stuff you're holding in your hand is probably something that molded a little bit. We don't really like mold of any kind and it's even not a great idea green crud growing on top of your soil Etc.

I don't recall seeing anything about temperature or humidity of your grow space, but when you have issues like any kind of mold you need more air movement. Oscillating flat fan blowing across the plants and the tops of the pots as well as ventilation pulling fresh air through your grow space.

If you get powdery mildew that is the bad stuff it is almost always a result of temperatures being low environment being a little wet and too little air movement. So I would focus on those things get your temperatures correct get the air moving good and make sure that you don't have too much variation between daytime and nighttime temperatures. The simplest way to do that is to run your lights 24 hours a day.

I would love to see some real good close-up shots of the bottom leaves of your plants, if they get some p.m. it will start their most likely. Otherwise more airflow hold off on watering until the pots get light and from what I've seen your plants do look healthy.

PS: once you get things sorted out have a Mod change the title of your thread and just turn this into a journal we can help you all the way through

Okay so I’ve taken some more pictures, and edited to pics to highlight my points of concern the best I can.

It’s more like parts of the soil on top are turning white, not so much a consistent residue, but only certain parts.

I should add I noticed this yesterday, but it is a lot more prominent and spread out today across the surface area of the pots. (Maybe I’m smoking too much and the LED’s going to my head?)

Anyway the temperature and humidity change throughout the day temperature is anywhere between 24c - 29c and humidity is between 47/48 -51/52%.

I’ve read so much varying stuff on humidity and temperature, so any definitive answers welcome.

I’ve added some pics of the bottom leaves too, I think this is the part of the plant you wanted to see?

Also you may need to look at the pics bigger in order to see the area I’ve highlited, especially on the first 1 as the area is highlighted using the colour black :/

Your temperature and humidity are just fine. I do see what you're talking about on the soil and what I would do is when they are ready for water, I'd cover that over with some fresh new soil right before I watered. Then get a fan blowing across those seedlings. Their stems are a bit thin and we like to use oscillating fans bending those ceilings over a little bit to strengthen those stems. If you had enough airflow across those plants to strengthen those stems you wouldn't have anything growing on top of your soil.

Otherwise things look fine and I really wouldn't worry too much about what's going on on top of your soil as long as your plants are healthy.

So get an oscillating fan blowing across the top of those pots to help give those plants some thicker stems and that stuff on the soil will go away. Dry up and die is what I mean and if you cover that over with fresh soil you're not going to have to worry about any mold spores going around your grow space. By the way a fan blowing across your plants keeps the mold spores that are always present in our type of growing environment from settling down and taking root on the plants.

I don't think you have anything to worry about... Decay in soil is normal and it wouldn't affect plant health.
What is your fertilizer schedule? Could be salt build up.

This would be great, except I have 2 problems, I have no oscillating fan, but I do have 3 small ones attached I heard that it wasn’t good to directly face the fans at them, but I’ve moved one so it blows the soil now.
See pics,

The second problem is that I have no more soil...

So anything else you can suggest? Or do I need to buy more? If so I’ll have to wait until the end of the month

Okay so my fertilising schedule currently is simply 2ml plant grow per litre, in they have 2 litres per watering, shared between 5 plants, so 400 ml of water each, they have only had 2 lots of plant grow on 2 desperate occasions at this dose.

They haven’t been watered since Thursday night, as I’m concerned I’m over watering and soil at top has remained moist.

I was planing to water them again tonight or tomorrow, 3ml plant grow per litre, and 2 litres in total, 400ml each, and I would continue water this amount and dosage every other day until week 4 then I’m unsure whether to up dosage or switch to bloom?

Some mycelium are beneficial. I had a layer of greyish white mould forming on some fresh mixed soil and freaked out! I hit it w rubbing alcohol and scrapex top layer off. Plants kicked ass tho.....? So then i read @pops22 thread on supercharging your earthworm castings . turns out i had jump started my microbial life w the mould. So long rant short your soil is alive!!!! Aslong as its not powdery mildew and the plants are clean of white fur ur solid . it may actually help ur grow!
