[torange]

Thoughts?

nute burn...

 

[wiseguy316]

i would give it ph'ed water with a peroxide to flush it for a day and make a new batch

 

[wiseguy316]

i don't think it is burnt,,might be a deficency or lockout....water & peroxide will get it back on track

 

[wiseguy316]

would help to see the whole plant, you may be over feeding it?

 

[rudy.racoon]

how much peroxide do you use with 1 gallon of water? Also is jsut regular peroxide you buy at the store?

 

[assasinofyouth420]

Yeah , doesn't look like Just any nute burn to me. The interveinal chlorosis and crispy copper patches looks like a problem I had when I over fed too much CalMag. Maybe you used too much epsom. Its starting on the older leaves first right?

 

[reggaerican]

after you get your feeding right try to lower your light an inch a day untill your leaves curl

 

[wiseguy316]

1 tsp of per gal of reg peroxide. 3 ml to 5ml of of 35% food grade stuff. I would reccomend useing the food grade stuff if ya plan to make any hash with it.

Stupid question I know, but what does hydrogen peroxide do?

yeah it is starting on the lower leaves first, I guess I'll dump my res and refeed with less mg, (actually I have calmag now, so I'm going to use that)... what benefit will peroxide have?

cleans your roots i believe..thats not nute burn tho thats a calcium problem..bad tap water i bet

 

[wiseguy316]

peroxide will get rid of bacteria, super oxygenate the roots and get them eating again if they are locked out

 

[assasinofyouth420]

You should only have to use CalMag sparingly. It's super easy to over do it with that stuff. I wait for signs that she needs it before I add it to the res.

 

[Cali.Grown>408]

i've never used cal mag..not necessary..calcium is high in my tap water..i use hardwater nutrients cuz its so high

 

[torange]

ok, well I just swapped my res with pH 5.6 0-8-16/gal flora, 3ml/gal h2o2, and 4ml/gal calmag, hopefully that's not overdoing it on the calmag. Im going to start flowering either tomorrow or the next day.

well am using filtered tap water (not RO) but I believe my water is softened... are my calcium levels likely still too high?

when you say softened you dont meen with a salt softener do you? if so thats all bad for your plants..

thats what it looks like..i get calcium spots to, but only on a few bottom leafs..if its not broke dont fix it..calcium spots aren't a big deal unless a whole bunch of leafs are showing signs of a cal def.
