PH problems?

by the brown spots on the fan leaves it looks like potassium deficiancy, but the purple spots on the stems could be of because of PH to high? havent really paid attention to PH levels 'till now...

what do you guys think?

looks like overwatering to me

not sure, but what'd id sat is if u didnt see those spots on the stem until u had the potassium issue its probably also potassium related

Looks like poor drainage to me.



The red on the stem is a sign of stress, could be suffocating.

this pics were taken right after watering thats why the puddels. the pot is 25 gallon soil w/perlight and bottom 1/3 is filled w/ gravel so i dont think it over wtaring. actually, it is so hot and dry out here i some times need to water twice a day so it cant be that. any other idias?

PH your water before you water then PH your run off if you think PH is the problem. Looks like a drainage issue,I don't see much perilite floating in that puddle

so what i'm gonna do now is try less watering, w/PH and leave the nutes as they are... hope to see resolts soon!

thanks every one for help!
