Need some advice. I think I broke her :(

[tomgrow20]

Hi all, I'm a serious noob at growing, and after trawling site after site, forum after forum I thought I had all the information I needed to begin my first grow.

Boy was I wrong as you will see from my pictures below.

So I decided on Hydroponics, and haven't even got that far as I have run into a serious issue already

Germination went as planned using the paper towel method, then popped her into a rockwool cube, that I has soaked in PH 6 water for 24 hours, then allowed to partially dried out. A few days later she popped her head out and seemed very happy.

After she had formed her first leaves, following information I had acquired on another forum, saying inert media would benefit from a small feed, I went ahead an gave her said small feed. That's when things went south.

To cut a long story short, this first picture is about 48 hours after she popped her head up. It was on this day I gave her:-

All half manufacturers recommended strength, PH'd to 6 and was at 225 PPM

Cannazym
Rhizotonic
General Hydroponics Gro
General Hydroponics Micro
General Hydroponics Bloom

This second picture was taken 48 hours following this feed..

After seeing these brown spots, I again trawled the internet in search of answers and am led to believe it's a calcium or magnesium deficency? which may have occurred due to lockout from the feed I gave being to strong or of the wrong PH?

Soooo, I decided to give her a flush with the following:-

1/4 strength of recommendation. PH'd to 5.8 and was at 87PPM

Rhizotonic
CalMag

48 Hours after that feed she now looks like this, very little growth, and still seems annoyed with me

Sorry for the long post but wanted to give as much information as I thought you'd need.

Few more details.

Water - Tap water, starting at 30-32PPM and PH 7.6/7.8
Light - Mars-hydro TS 1000 @ 18" / 18-6 cycle
Day temp - 24 - 25 Celsius
Night temp - 19 - 20 Celsius
Humidity 40 - 50%
Strain - Blue cheese auto - Dinafem

Any and all help very much appreciated.

do nothing for a few days, seeds need very little in the way of nutes. you could also raise the RH by cupping it, a little stretch would help you maybe. try and move a few of those stones away from the stem also if you can. how high is your light? try the grow FAQ page for more detailed steps that most growers here on the farm use. BOL to you, she will come around i'm sure of it. try loving it a little less

Most common new grower mistake to date. Seeds have all the energy and food they need to sprout and thrive for the first 14 days at least. All they need is Water and a little light.

Careful with rockwool cubes, too. In my experience they are more prone to damping off. In other words they hold water just a bit *too* well and are more susceptible to mold and disease in the first few weeks.

I switched from rockwool cubes for my clones and seeds to Jiffy cubes or Rapid Rooter plugs and they work much better for babies.

Cheers for the advice guys.

She seems to be recovering following my mini flush with just a small amount of Rhizotonic and CalMag. I only add the CalMag because my tap water is around 32 ppm and I read that it's very low so a little boost is likely needed to be safe.

I wish I came across this forum before I started the grow.

I'm hoping that by removing some of the stones and having a gentle breeze over the plant and rockwool cube the water should have a decent chance of evaporating, negating the risk of damping off, until the roots are actually in the water so I'd no longer need to top feed.

I'll post an updated picture tomorrow see if you guys think I'm better off starting over

I appreciate your time.

The light is 18" away? Is that too low for her age? I was worried she might stretch too much if I put it too high, from the specs on the light she should be getting 552 PPFD?
