Need help leaves are starting to get brown spots on them

[Cheterbob420]

I have a plant that has been in flower for 28 days. And now my leave are starting to turn a yellowish brown, I was thinkin that mabey it was the nute's and i was wondering if it would be ok if i just stoped using them and just use plain water through the rest of the cycles, but i wasnt sure if it would hurt my plant.

Are you spraying them with a foliar spray at all?

more info is needed and a pic would be good, plant size, pot size, lighting? temp? ph lvl? rh? etc............... but no, plain ol water wont hurt it

 

[Cheterbob420]

I would dump the "thrive"...If you are using RO add cal/mag...You might want to change the reservoir out. Just my opinion!

How would anyone here know that your growing in soil?

 

[Cheterbob420]

sorry for the lack of infomation i was in a hurry

I'd have to guess , you may need a little cal-mag. I had the same problem and it took care of it in a matter of days . I am doing hydro though, so it may be a bit different. But I'd still try thr Cal-mag... hope it works for you ..

 

[Cheterbob420]

[Cheterbob420]

they started geting little brown spots yesterday and today they are like that ^^^^^

and all the fan leafs on my plant have died off... i dont kno what else to do please help

 

[ol hippy]

Are you overwatering ? , underwatering ? Are you using all those nutrients that you listed there ? Maybe you should just drop back a bit flush with clean ph'd water, no nutes for a few days and see how things are.

 

[Cheterbob420]

i water every 2 days or as needed... i have curently stop using the nutes and i have flushed now for 5 waterings and it doesnt seem to be helping... my pot gets dry really fast could this be from to much air flow in my grow box... i am using a one window fan for intake and one for exhaust... my box dimensions are 4' high x 41in long x 21 inches deep

 

[ol hippy]

I don't know much about dirt grows but if they get dry too fast it might have to do with the soil , too much drainage ? I'd check that just a guess .

 

[Cheterbob420]

thank for the help man.... i think im gonna try and replant it with new soil

 

[Cheterbob420]

well i got good news my plant is making a healty come back...it looking real good ... but i had to cut all the fan leafs off cause they died will this hurt my plant?

 

[ol hippy]
