:( <====plants look like this

[Cosa Nostra]

Sweet seeds strains are well liked here. And well documented. They have their own thread plus smoke reports. Gotta be a good reason. My next seed order will have a fat pack of dark devils in it. How do you feel about popping a couple of the black creams? And what size space are you working in? LxWxH?

Should I buy a diffrent medium I have like 30lbs of promix hp left

I saw that tang uses polygron..so I dont know if I should go buy that or if promix hp is just as good..I dunno

What I start thinking also Is did I buy the right advance nutes for my medium? Do they have one for soil and one for hydroponics?

Im going to get some rest right now and give my brain a break! Good night man talk to you tomm.

Dont really know why this is happening. This is step by step what I did.
1. Rockwool ph to 5.8 and seed sprouted on heatmat w thermostat set to 80
2. (This might be where I messed up) I started to put pro mix hp in my 5 gal pot containers and insterted my rockwool in the promix hp without saturateing the soil with ph water. I watered around the sprout while most of the promix hp soil was dry only thing wet was the area where the rockwool was inserted.
3. Watered with ph water 5.8-6.2 for 5-6 days then started feeding with advanced nutrients phed 5.8-6.2
Now the problem started. Two autos started showimg deficiency first with bright yellow on first and second nodes which was stunting the plants. Three days later purple widow started to show the same signs of deficiencies.
4. I kept feeding with nutes for signs of deficiencies. Yesterday tested soil with soil ph probe. Tested 5.0-5.5. Flushed plants with phed water 6.1 to try to raise ph and then gave 2ml of nutes. now the whole medium is saturated for all three pots no signs of recovery. Seeing leaves wilting and dying. I do not know how to fix this problem. Pics will come within the next couple mins.

Your setup/equipment looks good overall. Seems that you use 2lights that hardly cover more plants than 2, but it is so hard to check what exactly you have into 100s of your posts, one sentence or picture in each. You had better concentrate your thoughts and photos in less posts to keep information together. If someone new comes to visit your thread, he needs 1 hour to get through your explanations spread around.

Seems that you screwed with rockwool first. Most probably you didnt prepare it properly in the beginning and you did not put it into dry soil after. After that you started to overwater heavily. You should put your seeds into soil directly, just under the surface, moist it with 50ml water and take care of moisture next 4 or 5 days until sprout comes out. Thats the easiest way.

And seems that you had flushed your soil with water to correct PH. More precisely, you had corrected very acidic soil with some more acid. At this moment your plant was sitting in extremely wet and acidic soil without any nutrients. With so much plain water in the pot, feeding is impossible. And here comes starving. Your plant is most probably hungry in tons of acidic water.

Not all waters are good for AN, so we must clear up about your water. You were asked about it before, but you didnt answer. AN sets PH into something what is supposed to be the sweet spot, but it is not always like that. Why do you get different results for AN PH?You say 5,8-6,2. When is it 6,2? What do you put into AN to rise ph?

Why do you need PH correctors besides AN? Do you try to help PH Perfect to work better?

TaNg uses Plagron Light Mix and AN Sensi nutes with them. If I'd grow in soil again I'd go with that, never heard anyone having issues with it.

If you are going to use rockwool cubes in future, soak them in the pH'd water first and never squize the cubes since they lose their ability to hold air as they should. I soak my cubes in pH 5.5 for an hour and then soak them in pH 6.2 for another. Then just seeds in and thats that. Since you are doing a soil grow, perhaps some pH 6.5 would be better.

Promix is awesome. Same as Plagron. I use it. You've already got it. No worries. 1. What type and size of pots do you have? 2. The size of your growspace is quite important. Get it measured so we can move forward.

Data vids and photos will all be uploaded today. Will start a new thread and keep it all together. Give me 4-5 hours.

So I've been talking the talk, let's walk the walk....
First up, a chart illustrating the importance of pH-

These are two seeds I started last Saturday. The big light (A SunSystems LEC315) is sitting in the corner gnashing it's teeth to get back to work. A bit of overkill at this point as well as a waste of electricity. This rig is a bit of DIY I put together back in the budget days. This is the third time I've had it up and it's been pretty effective. I'm actually curious to see what it's capable of in a full grow cycle with all 13 bulbs in. It was built to exploit the advantages of overlapping low level light fields and the low power draw of LEDs. I'm using 5 household LED 100w replacement bulbs, 18 watts actual draw for a total of approximately 90 watts. Color is cool blue daylight, 5000K. Got the bulbs right off the shelf at WalMart. If anyone is out there looking for a cheap light rig that can get the job done, I think she's gonna be tough to beat. Cosa, one of the Apollos that you have should be adequate to the task at this point of the grow. I'd guess 20-30 inches above the tops, but wait til they show before you plug it in.

So one day in a shot glass of plain water. The next day they were put into the rooters. Two days later they showed their heads above ground. A day after that the tap root was showing at the bottom of the rooter. BTW all these pics were taken today, 6 days in.

And if this root growth doesn't sell you....

Well I've got a journal to get started, obviously. But I'll be looking in dude. You asked for help, and I'm trying to give it. It's up to you to follow through. On that front, Shout out to Medgrower! At the end of the day it's really just about people helping people. Just that simple. Respect to you man.
