Ok so leaves are turning yellow at the tips slowly going to rest of leaves then the tips turn brown if i leave them long enough.. as well some leaves have little specks on them i think from fungus gnats sprayed for them with Dr. doom and then sprayed neem oil/dish soap water mixture on leaves. could this be lack of CO2 the leaves kind of look simlar to another person whos plants looked simliar problem to mine.. ill try and get pictures tommorow if nescessary to diagnose my problem.

humiditiy is ~52% and temp range is 83-88

I wouldn't recommend spraying dish soap on them to be honest

Your water ph might be a little too out of wack but I think your soil has too many ferts in it man...I could be wrong though. Try a transplant into a simpler soil mixture with less additives

[bloodbrother]

well ill check my water ph... i thought you were suppose to add dish soap to a neem oil spray its like palm olive for sensive skin but ill stop doing that and see if it helps thanks! im pretty sure the soil mix is good its a mix in the grow faq on this site so i assume its not too much nutes... i got 2 large rubbermaid containers full of soil mix with this mix.. but ill stop with the dish soap and hopefully itll clear it up thanks

Your soil mix is very very rich. It sounds like they are burnt, but without p[ics it's impossible to tell for sure.
Also, you do not ahve an actual exhaust, just circulation. You need both.

[bloodbrother]

ok ill snap some pictures tonite and post them shortly

[bloodbrother]

pics
what do you mean by rich? like too much fertilizer or...? because if something is wrong with that soil mix probably shouldn't be on the FAQ lol (the one accessible from main page of cannabis.com )... figured stuff up there would be on.

anyway here are pics

and here is the current setup going to be in a sealed box right away though with cooltube ventilation and passive intake

Your plants are actually healthy, if a bit root bound.
That is normal considering how poorly lit the low parts of the plants are. Those are leaves that the plant is not getting any use out of because they are less exposed to light and fresh air. More light to the undersides of the plants would have prevented that but it's not a big deal. The upper portion looks healthy. You'll want to re-pot quite soon though.

[bloodbrother]

that is such a relief... so on agenda today get bigger pots, finish growbox and throw them under 1000W HPS (well not throw but gently place).. and maybe take some new clones mine don't seem to be doing very well think left under humidity dome for too long lol.. but thats another story
