Short Stuff Onyx sick, help please?

[StealthGrown]

Help diagnosing would be wonderful. Appreciate it.

Shes got weak side stems, some tops of the stems are purple. One stem is very weak on the bottom. One leafs tip shriveled to bits. A couple little rust looking spots. But most importantly, the dark leafs that feel very moist and droopy. And there are a lot more calyxes now, I don't know why but these things freak me out. Shes still a female right? New top growth light green, almost yellow looking, but usually after that they go back to green. Temps have been awesome, humidity bad, and its gotten nutes once small small dose. The entire first grow I was feeding, then only pHed water, then feeding, then water... when I should have been feeding once and watering twice??

Can you give a humidity %?

Yep, she's a she alright!...Just finished 4 onyx the past couple of months...your's looks underwatered/ underfed....I started mine on light nutes at 3 weeks, increasing dosages until at max rec....I fed every feeding....
You didn't mention your lighting or nutes...appears you have some perlite in your soil...good...but it sure looks dry...
Onyx is some good smoke ...looks like ya got some good bud sites !!! Good karma sent for your success...

Hey Autowidow!
It ranges from 25-50%. Lights off its 40-55%, lights on with wet sponges on the intakes is about 28-40% max. Usually 30-38% RH when lights on.

humidity levels lower than 30% prevent the stomata on the leaves from opening fully (or at all) and reduce the transfer of C02 and other gases to the cells of the plant. Slow growth and symptoms similar to nutrient burn can result.

Thanks man, I asked because shes an inch next to 2 hermied plants- a himalaya blue diesel and an afgan kush ryder. What soil nutes do you use? Feed every watering without any burn sounds good to me, but i always got some reaction from feeding too much. Im using a 250w HPS and Blue Mountain Organic nutes- Flower Power and Grow it Green. Soils is Fox Farms OF. My soil sucks, I think it sat too long at the hydro store. Drys out too quick, sometimes wayyy too slow towards the end of the grow when the soil seems to just sink in and suffocate roots. So just give her some more Grow it Green tomorrow?

Appears you may be getting some good ideas on your probs....BMO is some good stuff... used it previous to my current ferts....BioBizz....and i use Humboldt Soil..which is nuteless...been doing great for me....I grow in 4" pots (yeah really small!) which dry out pretty quick under my 400w hps...
Get all the info ya can around here...some good growers here with plenty of help ....personally, with OF as your soil, I'd be a bit careful as it's already got time release nutes in it....never used it so have no input there....

You like BMO? Glad to hear it! They have awesome prices, seems like people give good reviews too. My BMO nutes are going to expire soon (After their 1.5 year shelf life), by late November-early December. Ever use them after they are "expired" ?

4" pots? Wow! How many plants do you keep under the 400 watter in those pots? a lot? Yea, the OF soil I have has some goodies in it, a lot of goodies supposedly, but no time realease nutes. They say the soils good for 3-4 weeks at max, then you need to use veg/flower nutes. They say 3-3.5 weeks then the plants will already go through the micro-macro nutes or whatever its called in the soil.

Just watered the Onyx with some Bmo GIG still at the small dose, but next one I'll bump it up some. Sound good?

Shes looking pretty bad! Light green patches still there, plus some new nasty hard brown and gray stuff took over some leaf tips. Like the leafs just healthy, then the next day dying. If I look under the leaf with the HPS on, I can see the messed up leafs and looks like someone painted them from underneath, the ends are completely dark. Plant looks alright still, but soon I can see this getting bad. Stem tops are completely purple, some very weak and floppy. Whats up with her? Should she get a flush or is this a simple fix? Shes only gotten nutes twice as of last night, before that she was fine on only pHed water and OF soil. Any incite or help on what I should do is appreciated.

I would say over water and a touch hot on the nutes dont go below 40% RH which gave mine dead spot
