idk how many ml are in a tsp lol i havent done tht i use a med cup and fill it to the 10 mark. and as far as cloning or being too soon to clone, you can clone whenever you want as long as its gonna be big enough to use as a cutting.
I'm kinda getting the tiny brown/ yellow spots you had. Did that go away once you added cal mag?
Yes, it was in my post, never edited or deleted. I just went by the images and descriptions I saw of the product..and it does not show any calcium or sulphur in it, and the magnesium is very low at 0.05%. http://www.greenhousemegastore.com/product/jack-foots-fertilizer-20-20-20/water-soluble-fertilizers
i couldve swore i seen calcium, i always add calmag anyways but never noticed. it has everything but that i guess lol but .05 is really all you need in my opinion. its not used by the plant as much during the whole cycle or a main in half of it.
Magnesium is extremely important, and most marijuana strains guzzle magnesium. Without it, or lack of it, you will have many other problems! The plants use magnesium throughout veg..that's why your leaves are green on a plant, it's the only metal present in chlorophyll They use even more during flowering! You haven't noticed the lack of it, because you use cal-mag. A standard gh floragro, which still needs a magnesium supplement, has 1.5% magnesium in it....30 times more than jack's, and it's still not enough most of the time.
ive done grows with jacks and didnt use calmag, the couple i did i didnt see any signs of a cal or mag def, i added dolomite lime in my pots at the beginning of the grow though so thats probably why i didnt get a cal def. . as ive changed things up over the years i added it bc one of my strains loved it. idk if its what makes the leaf green or not bc alot of other things can do that too like your b2 and N, lacking in cal alone can make leafs yellow or have spots so i wouldt say its all the mag doing it.very rarely people get an actual mag def so thats why i stated its not used as much as the others. could be strain dependent or could be marijuana in general i have yet to do my research on mag bc ive never saw it as a staple in their diets but one thats used a little throughout the grow. the things in flower i think they require are cal in the first few weeks, potash in the beginning stages of flower, and phos finishing out the rest of the grow. none of my flowering nutes have mag in them, none ever did. its something that needs to be built up during the grow like cal.
Calcium does not contribute to chlorophyll at all...the only elements in chlorophyll, are hydrogen, oxygen, carbon ,nitrogen and magnesium..magnesium being the only metal present and the equivalent of iron in our hemoglobin. Perhaps the dolomite was enough for your plants, or your medium contained enough organic matter..but i have never heard of flowering without providing magnesium, especially to cannabis! Magnesium is the heart of the cholorophyll molecule...nothing happens without it! Phosphorus is used just as much as magnesium is overall..phosphorus is used mostly in rooting and start of flowering as an energy source, but mg is used throughout in the same amount as phosphorus is. Also, if you're lacking in it, the plant will take up potassium instead, and leave phosphorus sitting in the medium, ultimately locking out everything. Magnesium doesn't get built up over the grow, it leeches almost as easily as nitrogen does with waterings..it must be provided throughout.
right i was saying it doesnt make them green bc what you said in the earlier comment leaned towards it making them green
and phos is used more towards the end of flowering. n then pot then phos
and as far as it leeching, if you have major runoff maybe, but i dont run to run off my friend. different ways of growing will give you different results i guess but one can be certain as we are not scientists and dont have the tools or means to test theory
The leaves turned full green again but the spots remained, although my new growth has not gotten new spots
ya damaged leafs wont recover like you said just look at the new growth and go from there
Okay so serious change , from my experience Jacks classic water soluble is TRASH for dwc. The Nitrogen doesnt break down in just water at all you can find the small clear sticks (as someone mentioned before) at the bottom of your reservoir after a change, never got used up. Jungle Juicd is a thing of miracles. im now using jungle juice micro and bloom mixing the "Lucas Formula" and adding Humbolt's Secret Golden Tree. ill never use anything else again, small grow or large grow. I cant say om awfully experienced but ive never seen plants grow this fast and healthy. anyone havkng issues with nutrients just go with jungle juice lucas formula
You need to fact check that buddy learn what phosphorus does and is before spreading info like that..at the end of flowering the plant is finishing up..that's not when it needs a sudden jolt of p! Not to mention nitrogen..the last 2 weeks can be left out altogether. Potassium is the main source of food for a plant during flowering! In any case..good to hear OP got it all fixed..i heard great things of humbolt's golden tree..will try it this spring. I used the lucas formula once with gh flora micro and bloom and cant complain for that grow.
these sugar leaves are now a great green colour and about the size of a dinner plate, also stuck to doing some LST and have a solid little canopy going with about 9 tops all even level, i havent tried Jungle Juice without the Humbolts yet so i cant say how much it helps i suppose but i am excited to start a new grow using these nutes from the start after harvest. Definitely going to use an aero setip rather than dwx next, my fathers 4 plants are extremely large and healthy using the aero systems and its his first grow. he hadnt topped,lst, or canopied at all so i do have more nodes and tops but they look great.
lol every feeding schedule agrees
figured id update since many of you helped me get this far. shes not far from harvest, got 6-7 more weeks and shes ready to hang n hit the cure can. (Thats a 36x36 x64 tent ) CFL only gro
Its looking great. Nice comeback and growing
