hello again everyone,

sorta made a thread on this before but that was last week and the situation has kind of changed now.

plants are yellowing and drying a bit, one isn't too bad, the other slightly worse and the other 2 are about the same, very thin and dry

would love some replies on this its got me worried thinking my plants are gunna die within a few days, seems it's started happening since i switched to 18/6 light cycle.

got 3 hours left today that i can still get to the gardening store for supplies

Wow things do not look so good... do you Ph your water before you water your plants? HAve you added any kind of nutes? The one plant almost looks like it got burned by the light... What kind of soil are you using?

the lights were like 6 inches or more from the plants until yesterday, no nutes yet, not sure on the soil just ordinary gardening cheap type stuff, i let the water stand a few days before watering them, thanks

I can't quite tell what is wrong systemically because it looks to me like you have different problems in each bucket.

More pictures maybe , close ups ?

Man o the green is right regarding different problems imo, but the 2 in the first pics look brutally burnt by nutes, if you have not (and you should never seedlings) feed them i would suggest the soil you are using is the problem, flushing with ph'ed water may help.

the other is the same as this, probably wont survive, very dry




this one is small compared to the other, going pretty dry now



the larger plant, not looking as bad but still yellow and will probably go dry like the others

I think that soil is the main problem. It doesnt appear to be a light well draining potting soil and it's ph is probably way off from were you need it to be. Not tryin to confuse you but adding or re-potting them in compost probably isnt going to do much good at this point, if I was you I would scrap it and start over with some decent "potting soil" like what was suggested before. Adding compost is not going to help you with drainage and probably wont solve your ph problem quick enough to keep them alive.

From the pics it looks like your plants are deficiant in nitrogen and magnesium wich is most likely caused by the poor ph of the soil, plants/seedlings should not be showing deficiancies that early as they dont need alot of nutrients yet, they just need a decent ph balanced medium/soil.

More times then not when problems start with the tip of the leaves and work their way in its a nute problem, it's either too much, not enough, or your PH is not set correctly so the plant cannot absorb the nutes it needs.

As others have said - they look either burnt or they are suffering nute lock out (getting some nutes but not others) due to PH.

Also, with young seedlings you don't need intense lighting. I would simply use a couple floro's untill they fill out some.

Well I hope they come around for ya, if not atleast you can learn from it. And if they do come around I would definately re-pot them in a better soil, something geared more towards horticultural container growing and not a bag of something intended to be dumped into an outdoor garden bed where mother nature works her magic, indoor growing is more scientific if ya know what I'm sayin! Goodluck, even if it doesnt work out theres always another day!

I dont think its actually THE soil that is the problem, its more whats in the soil. As long as the soil isn't packed and the roots are not bound the actual medium itself shouldn't matter too much (I actually use no medium)

You are looking at a nute/PH problem, plain and simple. Flush, flush, flush for a few days and if they start to recover add nutes in small amounts. Monitor your PPM and PH according to your medium and things should start to turn around for ya.
