first grow concerns...

hi guys, this is my first time growing, one of my plants has started to have dicolored leaves. the others are pretty good though. they currently get 8 hours of darkness a day. i water them every morning, and im using miracle grow liqid houseplant food. the seeds came from a bag of some headdies a bought. any thoughts or ideas would be greatly appriciated...

 

Well don't fertilize them everythime you water and do not water until the soil is dry. They need a wet/dry cycle for the roots fill the soil.

A guess would be Mg deficiency. Herb loves the stuff beyond what the generic fertilizers have. 1 tsp/gallon epsom salts should clear that up. Don't over do it though as too much can cause other problems.

They look pretty good though.

 

:hysterica oh oh someone said the MG word again...Hes getting them brown spots, BUDBILL has the cure.... yippi.. Funny that this topic is always coming up on the MG product.

 

Hee hee. MG isn't that bad if used sparingly. I always liked Peter's 20/20/20 it was well balanced and did the job well. It is the over application and underflushing that cause the problems.

Morning Dude!!!!!

I dont think anyone understands your Flushing on the soil.. Since SOIL its medium is porous and ease to irrigate, Using clear water flush out Build up of Nuits and check PH. should be 6.5 7.. any higher its gona have burned leaves and lower will have spots. like your getting. While The Empsom salts will remidey this to much epMg will make them worse..but you said that bill..
Can I ask also if they were recently transplanted? Root injuries cause leaf discoloration that resolves itself and plant adjust to the move? just a thought, so your not applying something thats not necessary..
Also Lighting has to be for MJ plants and not Incandescent light which cause discoloration since the plant cant produce Chlorophyll in the wrong spectrum of light..

Morning Bill.

 

Hey Dude,

Yeah but the size of the plants means they are still pretty young and shouldn't have had enough time in there to need flushing. If they were bigger, root bound and showing marco-nute lockout I would say consider a flush This just looks like a minor deficiency.

DUDE!

:H Hey bud, I should of said that also. that they are still small. Ok, how about a Reused soil? ... But Ive seen the discolor in a transfer, I should of stressed that more than a flush. But it is minor like you said..
