hey, thanks Mynamestitch, sproutco and all the others that have tried to help... things r looking much better, im feeding with half strength of veg ferts ec would be aboute 0.5-1, should i give them stronger mix next time... they have been under 12/12 light cycle for 6 days now, 1 of the plants r from seed (afghani x hindu kush)so i didnt know the sex until yesterday..it is a girl ...weeeeeeee :D
last feed was with half strength + 1 teaspoon epsom salts..

1 teaspoon epsom salts is quite alot. about 120 ppm magnesium. That should be plenty especially since you have dolomite lime. In future grows, better thing is to add 1/4 teaspoon epsom salts + 1/4 teaspoon powdered gypsum(calcium sulfate) per gallon of water along with the regular fert. This way you don't get things out of balance. Potassium, calcium, and magnesium compete with each other. If you add alot of potassium and magnesium with no calcium, you will end up with a calcium deficiency.

where to get hold of powdered gypsum? i hope i didnt gave too much epsom salt but the plants starting to show mg def. so i thought it would help(my veg ferts contains mg also)

You should be able to get powdered gypsum at a good garden center. Call around. You can substitute calcium nitrate at the same rate if you can not find the gypsum.

You probably can not have a magnesium toxicity...only just throw things out of balance.

or get pellitzed dolomite lime which is very easy to fine, i have found its must easier to find then gypsums

you can get it from hardware stores or garden centers hydro stores

Dolomite lime is not really soluble to add to water. Gypsum + epsom salts would not raise ph like the lime would. Plus, these two add sulfur which is a macronutrient (needed in large quantitys).

well dolomite limke contains both magnisem calicum and sulphur why put it in your water everytime when you can just put it in your soil on the top and set it and put soil over the top so everytime you water it works... wouldnt that be much easier?

Dolomite lime contains no sulfur. You might not always want to raise ph. That guy was just adding some magnesium to his water so thats where the suggestions started. You would want to use powdered/ground dolomite lime and not pelletized when applying to containers and potting soil. Pelletized is more for use in spreaders like over a lawn.

oh my god, its not just for lawn its for soil, what im saying is gypsum is much more time consuming to use every time you water when why not put lime in the soil
all growers use it just about all growers

sprout i got a question, are you growing now or have you grown before?

you think every issue revolves around ph issues........ i asked you before about you growing and you didnt answer it.........

not trying to be mean just wondering use some of the advice you give is out of wack :confused:

Most pro growers skip the dolomite lime and also don't use gypsum. They use calcium nitrate and magnesium sulfate/magnesium nitrate instead as there source of calcium, magnesium, and sulfur. This allows them to use the highest amount of nitrate nitrogen rather than ammonia or urea nitrogen. (ammonia/urea in large quantitys is actually toxic to plants especially in soilless potting soil) Ph is adjusted in the fertilizer water rather than rely on carbonates in the lime to maintain ph.

Sure you can use dolomite lime for potting soil. I do usually. But, you would want powdered/ground lime and not pelletized so it would be uniform as you mixed it with the soil or applied it to the top of the pot. Pelletized means "chunks". This would be easy to use in a spreader because you could broadcast it better.

FYI, I am always growing something. Lately, green/red hybrid cabbage and better bush tomatoes. About to start radish seeds in a week.

9/10 of all nutrition problems are ph related so...that is why I ask about ph sometimes first. :wave:

sprout im talking about pot, are you growing pot?

well around here [people use dolomite lime, you have a long way to go to catch up to grower lingo around here!

/10 of all nutrition problems are ph related so...that is why I ask about ph sometimes first.

not with cannabis, mostly its nutrient issues with nutrients not being used right because they are made for other plants

Lately, green/red hybrid cabbage and better bush tomatoes. About to start radish seeds in a week.

you havnt grown not one pot plant have you? this is not a farmers site its a pot growing site :)

i swear to god you seem like you have never picked up a plant before and grew it out
all your exp has come from books and school, if you have been around here growing at least 2 grows and been helping with peoples problems and learning from other growers then you can say you did something untill then i dont ever see you have grown a plant in your life! (cannabis)

and what made you come to this site? and again anyone will tell you, exp with other plants and treat cannabis the same way= one way ticket to death for the plant

cannabis and other plants= different
ask anyone who has grown before


you awnna see some of my plants i have grown?

here are my plants from first and 2nd grow's.

i got plenty more from more grows if you wanna see them

firstp lant grown, 7 foot tall mg brand products and soil

these pics are all one plant same plant, except for the one pic with the 2 blurberry's
grown with 400 watts light, all i had room for at the time

the last picture is the picture after a week in flowering, the result of that smal plant is what you see in the rest of the pics
the first 3 is blueberry from veg to harvest, one i had to get rid of because it ended up being male
so left me with one blueberry

hey, im back :) things r looking much better, but i got some questions: they still looks like they need some more feed? its 2 weeks since i set light on 12/12 they started showing flowers a week ago , i have just given them veg ferts at half strength(2 times since 12/12) should i start with flower ferts at wich rate? and should i still continue with veg ferts for some time?
another thing is that it have become very crowded in the box and the plants r full of branches on lower part that wouldnt get much light(im only using a 400) should i trim the lower part of the plants i did this a week ago but still its really crowded.

canna terra vega: NPK: 14-6-17
canna terra flores: NPK:10-9-19
both veg and flow ferts also contains magnesium, sulphur and trace elements: Bo,Cu,Mn,Zn,Fe-DTPA,Fe-EDDHA

i also have Ammoniumnitrat 34% N havent used it tho.
