what type of soil are you using? i like to give them a little superthrive fert after a trans plant.1 drop of superthrive a gallon and maybe a half cup of FOXFARM BIG BLOOM and then add and airstone to that for at least a half hour mix well before applying

 

[bigbuddha22]

Something generic from nursery was literally white bag labeled organic soil :\ i added the perlite and vermiculite, and i've used superthrive on them forgot to put that sorry

also try getting a five gallon water bottle then take that to a 25CT a gallon water station,voila water problem solved. the PH in your medium is off due to the hard water u use,therefore causing what we call "locking up" your plant cannot up take all the nutrients it needs when the ph is off locking out alot of the nutrients your plant so vitally needs.therfore causing deficiences and your plant will all together stop growing. get bottled water right now and then use that to mix your nutes use tap when your just watering without nutes your ph should be ok after that regimen

 

[indoor/outdoor]

a ph soil probe is like 10 bucks at the hydro store stick it in and it will tell you your soil ph. your soil ph should range from 6.3-6.8 with fox farm soil feeding .DONT FORGET ADD A AIR STONE AND A AIR PUMP TO HIGHLY AERATE THE NUTES YOU USE I USE FOXFARM oceanforest soil in five gallon black buckets and i use all fox farm nutrients and additives I like to use other things that are organic such as mollasses and alaskan fish fert also maxi crop seaweed and superthrive

 

[bigbuddha22]

So you think it is the ph? How come outside they were looking so good? I don't know

 

[bigbuddha22]

Ok so I tested the ph with an analog ph tester, and it ranged from 5-6 how could I go about correcting that?

Thanks again

i would guess there are not much or any nutes in your soil mix, and your lil guys are starving for some Nitrogen

 

[joe fresh]

ORGANIC SOIL????


it looks to me as if someone is selling you re-used garden soil....look at all the weeds and stuff growing in it(not the mj , lol)....


my first guess would be bad soil with bad ph, my second guess would be over watering.....

 

[bigbuddha22]

Ok so nutes I got fox farm trio what of what should I use and how much

And what.should I do to fix my ph?

And is 18" too far or too close? Temp stays around 78 or 79 at plant tops

Once again help appreciated, plus I really dunno how to give rep lol

 

[walt cunningham]

i would use the grow big at 1/4 strength

 

[bigbuddha22]

Use grow big and big bloom?

Foxfarm feeding schedule makes no sense to me lol

And what about raising ph as its currently brtween 5 and 6?

 

[bigbuddha22]

Joe fresh, I think those weeds are from when I had it outside as where it was outside it had multiple of those weeds, the ones I had on window seals don't have them

 

[walt cunningham]

did you put anything in your mix like dolomite lime for ph?if not just start adjusting the ph of your water with ph and down or whatever.
18" is fine

 

[bigbuddha22]

I didn't for this soil, I bought some for next batch its already cooking, with added bone meal, blood meal and worm castings and base is ffof but thats completely unrelated so no, there isn't any lime in this one


And should I use big bloom and grow big in same gallon of water together?

 

[walt cunningham]

no don't mix them

 

[bigbuddha22]

Walt, so only use grow big? And to person who said use ph down in water, shouldn't I use ph up since my ph is.5-6 now?

Thanks again
