So as you can see she is suffering from something but I cant figure it out.

This plant is 30days from sprout.
used 40w of 6500k cfl and just increased to 85w of 6500k cfl 2-3 days ago is now kept 6" away from top of canopy
RH is always above 25% (avg 30%)
circulatory fan added yesterday& no exhuast fan yet (have one but have to work on sound proofing) turning off for now
Temp is always above 68f sometimes peaks in mid 80s (82ish)
was watered 4 days ago with a bit of molasses(still kind of moist half inch down, the top soil just looks dry)
the water used was bottled water which i just discovered is RO
tap water will be used in the future to correct this
Never fed but there are fert spikes made of natural ingredients (kelp, fish, feather &bone meal 6-4-6 ) mixed in the soil
kellog organic potting mix

it's increasing rather rapidly so the fan will be turned off for now just incase
Not sure if it is a mineral deficiency, heat/light stress, fungal or mite, or watering issue(though the plant does not seem to drink a lot) or possibly wind burn?
Thinking a molasses foliar spray may help, need suggestions pleaseIMG_0415.JPG

I would get a meter, ph is pretty important as it can cause nute lockout

I would like to get one but I am on a tight budget and I always hear about faulty readings. Would you be able to recommend one for me under $20 ? i also want to keep this grow organic so what can I do as far as stabilizing ph organically?

You need to have a fan blow on a new plant to help strengthen the stem. Just enough to cause the plants leaves to vibrate is better than nothing. There's also a need for airflow. If that yellowing continues to take place at the lower leaves, it might be due to low nitrogen. I see you have fert in the soil but it takes time, several weeks, for that kind of fert to break down to a molecular level that plants can absorb. I say keep an eye on it and if the yellowing of the lower leaves gets worse, consider giving a small dose of fert. You can get a cheap fert at a hardware store like home depot or lowe's for just a few bucks called Schultz. Last I used it, the dose was 7 drops in a gallon of water. That isn't much, but it worked. If you want to spend more, but you probably don't, then I'd get some Dynagro at the grow store or amazon. You can find the 8 ounce bottle, which is the one to use in soil as you only need 1/4 tsp for soil. This info is only is the yellowing gets worse on the lower leaves. If that happens, I think it's a good guess that you need some nitrogen in the soil as low nitrogen levels cause a plant to put it out of the lower leaves to feed new growth.

Looks a little hungry to me and switching to tap will help by adding some calcium.

Is a calcium def the only thing going on here? I want to rule out everything else so I can start solving this.

the leaves aren't really yellow at the bottom its more going straight to brown spots. the yellow is more apparent on the new growth. I would like to use organic solutions for my grows though , do you have any ideas? I think I want to give it some better water flush before I add nutes just to be safe, will the plant

As far as longevity how did it hold up? I will def order one right away though to fix this. Do you know can i adjust my water's ph organically?
be ok if i do that?

I've given you the help I could. I don't think I'd flush. I'd use a well-rounded fert once by following the directions and see what happens. Be careful not to over feed.

I did some research and the water I was using is normally a ph of 5. i def locked out some nutes. I waited about 11 days since the last watering and I just gave it some tap water which is pretty alkaline. Will update with results

Hard to believe it was 5. Maybe you should test it, or just never use it again, whatever it was. That's water will a lot of stuff in it.

Not many people will be able to guide you very well because none of us use kellog organic potting mix. Next time stick to something like fox farm ocean forest, many many people know a lot about it and would be able to better advise you based on their experience. With a dirt like FFOF you typically dont need to fuck with it until week 4 or 5.

So what I've learned that it was definitely caused by my bad watering habits( sometimes overwatered and sometimes underwatered) as well as switching to tap water and feeding Fish fert/ molasses helped a lot. The plant has recovered though! I just topped (though i dont think i cut it low enough for my tent space, and i topped it 2 months into veg :( but we will see how this goes lol)
