Bad soil - Plants are/were dying

[latinpruner]

So I had my setup really good, inline fans, outline, temp control. MH, grow tent, but I was a bit of an idiot and used soil from the garden centre which was cleana and free of other stuff, but the plants were growing, but slowly, I lost a few, yesterday a few started to go yellow on the tips of the leafs.. The soil I am using goes rock solid whether wet or dry,

Remedy which I am hoping works is I got some specialised soil from the grow shop and repotted them, trouble was, I had to chip away a bit at the soil to get to the root to repot them in the moist perlite soil, which may have caused some damage.

I watered them and the light is back on so I am hoping they are fighters and can recover.

I initially thought it was a heat problem, I was using a MH, then I switched to a HPS, I have a 2000watt LED grow light, thinking of using that if these survive..

What do you guys think? Are my plants doomed? or will the new moist perlite soft soil offer some much needed recovery? I've also put an external AC unit to keep the tempt at around 25 degrees celcius..

Rock hard soil might not be the soil.
Could be heat.
Could be hydrophobic from your watering pattern.
Don’t think a garden center would sell bagged soil that has that much clay.
What’s the brand? Ingredients?

Your plants will recover. Just give ‘em time. Don’t overwater. Let the roots stretch out and search.

Hi guys, here is a photo, 3 of them I put in big ass pots with the soil and perlite, the other 3 I put in smaller pots with the same soil, recently did this around 2 or 3 hours ago and watered them. Using a 600 watt HPS light, AC unit, grow inline out fan, with AC unit outside, humidity is at 55% and temp is at 24 degrees celcius

Pretty sure it was the soil. I noticed the fluffy difference straight away from the original soil, and the new soil which was fluffy.
But could have been watering schedule
Hoping they are robust, they still have the roots intact, they are a bit floppy but they dont look like they are dying apart from the slight tinges of yellow which now they have essentially been transplanted will be rectified

What happened to the 600 watt Mh yesterday?
Either way 600 watts over those tiny things in big pots is a waste of electricity
I would use a couple cheap leds or similar till those tiny things fill up the root zone
No offense but you have several grower error issues
WELCOME TO RIU

Agreed. 1 your soul still does not look like u saturated it with water leaving dry pockets. Roots won't grow in those spots and soil will harden, when you water it water and nutrients will skate across hard soil and never get wet. Your loosing pot space by under watering. 2 600 watt hps is over kill for those babies too. You can use it but u need to keep it 4-6 feet away and let them get away from being babies. A Mh bulb be better for the veg stage, hps for flower. The plants are young tho and have 99.9 percent of their leaves to grow still... so the bad ones on the plants don't matter so much as long as they are strong enough to grow the next healthy leaves, you have plenty of time for a strong recovery

I had a 600 watt MH which I was going to use for vegging and then switch to a HPS, bit I figured to lower the heat I would swap to the HPS.
Thinking of watering them again, guess it's a matter of time, and a learning curve, at least I'll have some idea on what to do on the next one...

Soil def looks a little heavy, in combination with the very large pot size for very small plants, as well as you being a newer grower. You'll grow out of all of these small things and kick yourself in the ass a bit for not getting a proper soil to begin with but that's part of the fun

Heat is generally fine in veg
The blue from a MH bulb promotes growth and is important
It would be better to do an entire grow under MH vs HPS

Hi guys
Reverted back to the MH, and repotted all of the plants, it seemed like they were dying due to not having enough root space for growth. Will post some photos up, problem is now I have 3 large plants and 3 small plants, I'm thinking of flowering 3 under a 600w HPS light instead of the smaller plants. I have 3 that have grown fairly well..

This has definitely been a huge learning curve, lots of mistakes, lots of corrections, biggest thing I have learned is to just let them be.. I think playing around with them, watering them too often, etc caused some damage.

I needed to use the right premix soil and pots which was also an issue, Since I repotted them in the correct soil and bigger pots they bloomed.
