I'll be the one to say it this time, you're Going to have to give not info. Medium, water (and ph preferably), nutrients, lighting etc. Could be a few things.

If you haven't seen this, it can be a helpful start to diagnosing problems.

Im using fox farm ocean soil and dyna gro nutes. My lights i was using 2 23watt 5000K, 1 60watt 5500K and 1 42watt 2700K and 2 32watt 2700K and 1 more 23watt 2700K. My temp is 73-76 and at night is 69 My humidity is from 50 to 60 but my humidifier dosent have a filter and some white stuff from what i think its the water is flying everywhere, i dont know if its really bad. Ive been on top of my ph and i stoped giving nutes a while back because i belive it started as a over watering problem, then i got N toxicity or atleast thats what it looked like. Then it looked like K.P deficiency. The thing is that its shown different symptoms every time,

don't give the dynagro with ffof soil. soil has fert already.

Tap water? Ro? Have you been doing the Feed-Water-Water technique? Are you adding any Calcium or Magnesium on the water only days?

Judging by plant size I'm guessing he's far enough along that he should be feeding mildly by now. Unless you recently transplanted to much larger pot. See this introduces lots of fresh soil when you upcan like that thus sometimes delaying the need to feed.

I know it has fert but isnt it good for arpund 2 weeks?

Orbo- i use drinking water from the small water plants outside the stores, i check my ph . feed once a week but i did not know i had to use calcium and magnesium on water only days

orbo · Dec 16, 2015

Oh....yeah man. She's looking like she needs some Calcium. Look at the charts provided by Tommy and see the Ca deficiency sections.

Are you going into flower yet?

Be careful with the lime...it'll burn shit up if not used properly. And if you're going into flower then you absolutely need Calcium and Magnesium right now.

I've never tried it and I hate suggesting something I've never tried it but I understand a crushed up Tums will net a good bit of Calcium immediately. Maybe @hotrodharley can suggest a dosage with regard to the Tums? Option 2 is eggshells in white vinegar. This will take a minimum of 2 days to prep (with the right tools, more time is better though) but it works well for Calcium. And you can use Epsom Salt for the Magnisium for this emergency fix

Get out of that Lime thread. Lime is best when added while you're mixing up your soil - BEFORE you let the soil cook. If you add it now its likely to add to your problems.

polishpollack · Dec 16, 2015

continuing to feed the dyna gro is a mistake. no one knows how long soil will last. probably longer than two weeks.

Árboles verdes · Dec 16, 2015

Ok so

Ok so the calcium, how do i do this? Crush a tums and mix it in the water? Or the egg shells just crush and leave in vinegar for a while? Can i just buy some cal mag?

Im gona buy the fox farm nutes, im thinking ive been over killing because the ff nutes go with the soil and the ff nutes npk is really low, that means the soil has a lot of nutes right?

Of course you can buy some Cal/Mag. My suggestions were household items in case you couldn't get any cal/mag quickly.

Árboles verdes · Dec 16, 2015

Im gona order next day shipping. And to feed my plant it would be only with the cal mag right? I really appreciate your help. Thank you

orbo · Dec 16, 2015

Yes, hold off on the nutes for 1 watering (or maybe even 2) and just hit it with pH'ed water and Cal/Mag. Next week about Xmas time re-evaluate and maybe a light feeding..or maybe not. Let her tell you.

Cool, thank you man. I'll let you know what happends
