Hi there from the land of rising (not telling)
I have recently started my little grow room.

I have a 120 watt grow LED in a grow room of 700mm wide X 550mm deep and 1.7m high.
The LED is sitting about a meter above the little feller.
I have a fan in there at the moment to circulate and running around 26 degrees celsius with a vent at the top and bottom of the grow box. (I have also just invested in a humidifier as it is dry here in winter, but not installed yet)

I admit I overwatered the little one before (and I mean sopping)and it seems to have led to some discolouration and the leaves shrivelled up. (That was 2 weeks ago)
I quickly changed the soil for a soil & perlite mix and repotted it.
It is now at just over 3 weeks since it sprouted.

I am potting in a perlite / soil mix (PH 5.5 - 6) with a 40/ 60 ratio.
Soil is called "HYDRONEX" (Japanese soil mix with PH level of around 5.5 - 6.5
There still seems to be some discolouration and it seems to be a little slow. (or is that just me?)

I can't tell if that is burn or still the affect from overwatering or, just LED discolouration.

This is my first time to grow for around 20 years and I used to adopt the "throw it in the ground and see what happens" method when living back in OZ.
Am I doing something wrong? Is it on a healthy recovery? I don't know.

Any advice would be greatly appreciated.
Please note I am on a tight budget and not living where I can readily get all kinds of chemicals etc. (or order them into the country)

Is your soil pre-fertilized as it looks like nute burn - it's definitely not light burn your LED is far enough away - maybe too far ( just an observation ). I would go easy with the water, get a dry - wet routine running as in water - let it use up the water, till it's light, then water, as your roots need oxygen as you know - have you noticed any new growth - if not I'd pop another bean as this seems to be a bad start to what could be a great plant, remember getting the pH right is the best way to start, then check your run-offs pH it should be 6.0 - 6.5 in soil.

I'll hear about this but with good quality potting soil the need for Perlite is diminished to eliminated.That is old hat from way back when. When soils could not contain moisture and needed to be made less dense. Not saying don't use it but Perlite holds moisture and your nutes. Add more nutes and what happens? Water is quickly used, the nutes that are not taken in accumulate in the Perlite and it goes on and on.

I know you can do a hempy style grow in straight Perlite so save that crap. Just read about the water & nutes in hempy if you are going to use this much IN the soil and adjust your water & feed accordingly.

You are growing half hydro and half soil. Work to find a happy medium between the 2 styles with your pH and feeds.

Thanks for the info. It is pretty hard to tell as all the info is in Japanese. (My Japanese is almost fluent but I am dealing with a totally different vocabulary set) With the PH level written on the pack as between 5 to 6.5, and specifically designed for Hydro/ indoor plants I am guessing that note burn may not be the issue. However, I did mix a tiny little bit of guano in the mix as I can't find any fish emulsion etc. (However, I have been reading that adding that may be better in the flowering stage)

"Using Perlite and Vermiculite is still technically considered hydroponic (not soil), so you'll need to use a hydroponic pH range (5.5 - 6.5). Magnesium and Calcium especially tend to get locked out when the pH near the roots drops below 6.0. If you adjust the pH to the proper levels, this problem should clear right up."

Good point. The soil bought actually had a lot of material in it to provide adequate aeration by the look of it. May have gone a little overboard. Will reduce the perlite ratio with the next bean. Will keep you informed

You need to adjust your water and feed now! Read the link I posted for you.

The feed is going to be a fun one. Unfortunately, I have never seen any of the of the brands mentioned in Japan. Any tips on what I should be looking for, or any homemade solutions? Thanks for all your input and advice. And once again, apologies for double posting the thread. (Possible to delete the other one?)

Don't sweat the multiples. We just ask this to new members who do it. No big deal.

Plant food is plant food. It really is. Anything good for flowers or vegetables will work including the old true blue Miracle Gro. Find out what is available and put the numbers up here. Many here will help you adjust your feeding.Meaning the NPK figures on the bag or can such as 5-1-1.

Serious growers always invest in a good EC/PPM meter. Know your water PPM and its pH. Adjust the feeds from there.

Thanks.
I have put a couple of pics up of the soil I am using. Although in Japanese, I think you can see the PH levels etc. It also seems porous enough. (maybe repot without the perlite mix?) There is also a plant food advertisement on the back but, it has NPK of 6.5-9-19. Look for something around 5-1-1 you think?
Thanks for the help. Starting to get my head around this. Will invest in a PH meter too.

You want a higher nitrogen and lower phosphorus, lower potassium to veg with. You should continue to use the veg formulas into about the 3rd week of your flowering. 5-1-1 is a little weak.

Was pretty tough looking for the N-P-P ratios. Best I managed to get was a 6-5-5 plant food.
The under leaves are still brown and curling but the top leaves seem fine. Stalk seems to be fattening up.
Changed to LED for some CFLs to see if that helped.
(Got myself a PH reader, soil was about 7) Will give it a good flush when she dries up and check the run off.
Got a heater cause it damn cold here.
Also dropped another bean so I can start to experiment with where it went bad etc.

Will let you know how it goes.

Add something like Alaska Fish Emulsion at 5-0-0 or 5-1-1. You need more N in veg.

Begin by adding it at 1/2 strength of what is on the bottle. Then follow with two waterings of just water.

Will do. Thanks for all the tips. The 6-5-5 that I bought, be any good in flowering stage? Or best to tip it on my radishes and tomatoes?
