I have looked around at various people's posts on their plant problems. I have also read growfaq, etc. First off here is the set up.
2-4' T12 shop lights. Temps 65-77. Bagseed, 46 days old from seed, Fox Farm Ocean Forest. My water is R/O and also water softened by Solar Salt-around 6.0-6.2 PH. Nutes are BMO Super Plant Tonic, and Grow it Green. I use SPT now and then. Grow it Green once a week, and plain water the rest of the time.
I'm wondering, does my water softener kill my plants?! My problem fits into many different deficiencies.
The last 2 pics are of a plant in flower(1 week 2 days in), MG soil, BMO Flower Power nutes, temps 65/77. The discolored spots are a brown/rusty color and crispy.

Thank you for any help you all provide, I really appreciate it. I'd like to get these problems sorted out so I can purchase some actual seeds.

i would get the plants out of cups and put them in pots. do the cups have holes in them? then i would give them nothing but straight water for a week and see how they respond. how are you measuring ph? why ro water?

Yes those cups have holes in them, 5 in the bottom, and they do get drainage. The roots are at the bottom of the cups, would that mean I need to repot and that's my entire problem? I measure PH with a cheap fish tank test kit from wal*mart. R/O water because it's either tap water that goes through a softener, or R/O that goes through the softener. I just figured the R/O is better. I think the tap is like 7.8 PH, the R/O is like 6.0. Thank you for your reply capn!!!!

Also, when I use nutes, I have yet to go full strength. I range from 1/2 to 3/4 when I do feed.

Correction: My R/O water PH is about 6.4
Tap water PH is about 7.2

bump..anyone..?

Wow... someone who's plants look exactly like mine. Yeah, same thing is happening to my plants, and the problem looks exactly the same.

I really wish I knew what was wrong too... It's hard to get answers. Everyone just posts their "guess" on what the problem is, and usually its the wrong answer.

Today I tried adding diluted lemon juice to the soil in case the pH is too high. The growth of my plants are also stunted, is that happening with yours?

Oh and I am also using the exact same lighting as you... 2 4' T12s, and one 36 watt cfl.

Filipino - Sorry to hear your plants aren't doing so well either! And it sucks that the wrong answers are given. However my plants are still growing.

I am Not and expert. But my advice is this.
I had high PH to start off with, and that will lock out your nutrients and make it appear as you have nutrient deficiency. If you have access to dolomite lime, horticultural lime, or even a product called Ferti-lome Soil Acidifier, it's a bottle of liquid, that should help. There's also peat moss, elemental sulfur, and the lemon juice works if you do it more often!
High PH levels cause a reduction in phosphate and trace element availability.
Hope this helps. Good luck! PEACE!

The salt content of your water is probably pretty high. Looks like a few symptoms going on there. Deficiencies , and possible salt overkill. Start using DFistilled water to see what happens....

yeah, that is what was happening to me.

The best solution is to get a ppm pen. Test the water COMMING OUT of the BOTTOM of the pot. It will hold many clues as to what is going on. If the water going in is at 1000ppm and the water comming out is at 4000ppm, you have a problem. Same thing with the pH, if it is way off, you got to fix it, if you ppms are comming out pretty much the same and so is the pH, then at that point it may be a feeding problem and you may want to add more nutes.
