thanks man on the real peace

Wow....was there an earthquake in that grow room. :smile:

I use MG as well to start with you have to only give them a small amount,,,, Wait A min let me get my cam and I will show you

O.k. with what I got it said use 1 tablespoon for every gallon of water for a large mj plant outside in the ground you can get away with that after it has built up (let say a tolerance ) to the food and then they could only take that every 4-5 or so and you would have to water them good with water before and after you poured the gallon of food on them






what I do is,,,,,, the spoon that came with it the big end says 1.5 TBS and the little end says 0.5 tsp so it has never been used

I got some little spoons from the dollar store that has wrote on them in big letters and numbers what they are and I use a coffee can I guess its about 1 gallon IDK anyway and my little measuring spoon says 1/2 TBS ,,,,, I put a even 1/2 TBS spoon full to a coffee can full of water and I don't just give them high N this one

during the veg state I give them this one

then 4 days later I give them this one

but when flowering I only give them the bloom booster and I feed every 4 days and that seems to work good for me with a small indoor plant,,,,
since you have extra food in the soil all you have to do is over water it let them extra water run out the bottom then over water it again and one more time that should wash all that extra salt build up out of your soil ,,,,Its called flushing the soil just put it out side or the bath tub and water the hell out of it that will wash out all the food thats in the soil

and that ugly little dead tip just take a pair of scissors and snip it off its not gonna turn back green or anything

have you got them 12/12 ? have you already got buds on them?

12/12 from seed. building a mother/veg box as we speak. got some other seeds started for that. i hope. i might have feed them to much. the drainage was not good ether. new pot fixed that. flushed it very good last night so lets see what happens.not going to water them for at least 5 days. or till the leave show drooping. what u think. anyway thanks

I just got back from all mart myself I got some 42 watt CFLs some emergency blankets ( mylar type stuff ) on the back it says .Made of polyester material designed from insulation used in space exploration. lol I got some jiffy pellets ( pucks for cloning ) ,,,, plastic drop cloth ,,, lamp sockets ,,, and two bags of soil ,,,time to have some fun !!!

the way the wind is blowing and sun shining if you can put them outside it will help dry out the soil
