Hi guys, Could you recommend where in Sydney I can buy suitable soil for seedlings? I bought something in Bunnigs (see below) but my seedlings look really unhealthy and it was suggested that the soil is too hot for them. Here are some pics of my plants...

Is a metal-halide lamp better for grow stage than HPS? I think I have one somewhere..

The thing is, here in Australia I struggle to buy soil that wouldn't have any enhancing stuff already in it... :(. The manufacturers put fertilisers in it because that's what sells I guess.

At this moment I only have the HPS and some big CFL. Do the CFL provide a better spectrum and I should swap them for the HPS? At first I kept them in smaller pots and I put them into these bigger ones after two weeks. Not sure about the exact type of soil. Something I bought in a garden...

My over 2 weeks old plants look terrible. The leaves are pale green, turning yellow and drying. Now they have started rolling and tips turning up. I can't figure out why it's happening. The soil has some nutrition already in it from the supplier so maybe that's why? First week I had them under...

Thanks guys for your responses. The medium is a mix of soil, coir peat brick and perlite. The temp is between 22C to 28C. Not sure about humidity. I'll have to buy something to measure it... I chose this type of pot because the instructions says that I won't need to take the plant out of them...

Hello guys. My young seedlings (almost 3 weeks old) aren't growing and their tiny leaves are yellowing. I water them about every 2 days because the soil gets dry quite fast and the pots seem to be really light. The light is about 11 000 Lux. The yellowing and overall not very healthy look is...

Thanks guys for help. I started adding Cal/mag into feeding and it's already started showing sings of improvement. I just wonder why the Epson salt didn't help. Maybe it's as useful as milk as calcium replacement...:).

Yeah, we had some ups and downs, I admit :). But I still don't know what it's flowering. From your reaction I understand you don't think it's worth of waiting? I should just chop it down and start again? :(

I have a miniature plant that is flowering but the leaves and flowers are kind of strange and I struggle to determine if it's female or male or something between?

I struggle to diagnose what's wrong with my 2 plants. First they were infested by mites. After 2 applications of some spray it looked like things were getting better. But now, I'm facing a different problem. Dark (mostly brown) spots are appearing on leaves, then the leaves are turning yellow...

Wow! It looks like you're right. I found some rust-coloured creatures. Very small. How can I get rid of them? Is it bad for the plants to host them?

Almost all leaves of my 3 young plants have small yellow dots and some of them (bottom ones) are all yellow. I've measured about 60 000Lux on the top leaves. Is it too much?

I've read that even a little light (a small leak inside your tent or a light from e.g display of some electronic device) can cause that your plants will not start flowering. Supposedly if you can see your hand in front of your face, there isn't enough dark. Is it really so? I struggle to believe...

My 10 days old seedlings don't look very healthy, their small leaves are turning into yellow. They are in 70% coco and 30% soil. 2 days ago I gave them first fertilizer (mild concentration) but it apparently hasn't helped. The mix coco and soil gets dry very quickly, I have to water them...

No funky smell from the roots detected. I'll give it a proper watering and skip 1 or 2 feeding and I'll see if anything will change. Thanks for your time guys.

Eh. Thanks for your feedback but it's hard to choose which opinion to go with. One says hungry, the other one over fed. :)

At first I thought nitrogen deficiency as well, but in my food there is plenty of it. And I don't think I'm so close to harvest yet. And also, it seems that the yellowing is getting from the bottom the the top :(

It's soil mixed with some perlite, in about 12L (3 gallons) pot. 2 weeks ago I started with flowering food, 18:6:28. I usually put about 4ml from each bottle (see pics) into 1L bottle for watering. I water every other day and I put food into every other watering. Temp is high, it's summer here...

My plant is in flowering stage and a strange yellowing of (mostly) bottom leaves have started happening. Maybe lack of magnesium problem?
