PICS ON REPLY What type of medium; soil or hydro? COCO What brand and type of soil? botanicare coco Indoors or outdoors? indoors What strain? thc bomb How old are the plants? monthish from seed sprouting What type of lights and how many watts? 400w hps How far from the lights? it's hanging vertically, almost directly under 10 inches maybe? What is your watering frequency and source of water? tap water with tds around 180 1/8/2014 17:50:12 Small THC Bomb Canna veg a+b sweets nutriplus gold 1040 6.2 r unoff 859 6.3 was last watering cycle 1/7/2014 21:56:53 Small THC Bomb Canna veg, liquid karma, sweets 923 5.8 runoff 686 6.1 What, how much and when was it fed? NPK? What is the medium/runoff pH and PPM if in hydro? What are the temps and humidity in the room? huidity stays low, basement room between tents is where my humidity meter is, never gets over 35% or i turn on dehumidifer, i have a flower tent too, temps never exceed 27 or open window to -20c weather which lowers humidity What size pots? it's in a idk 1gal maybe 2gal pot? Any bugs? Look real close. no Any other pertinent info think its calmag prob but idk if im under feeding over feeding, im studying coco feeding with every water or like hightimes suggested day 1 feed, day 2 water ph day 3 nothing.... any suggestionS?
tends to be lighter colour between veins which are darker, only on big fan leafs, nothing on new growth,heavy calmag along side feeding the solution?
Don't know much about coco but if the numbers u posted were ppm, seems high to me for 1 month old. Maybe cut that in half. Just a thought. Seems like everything else is in order
Your working on a minor deficit. Bring the ppm's down as TheAnswer121 advised and bring the ph of your Coco medium to 5.8 or you'll be missing out on P, K, and Zn. http://boards.cannabis.com/attachments/plant-problems/281235d1325194867-brown-spots-some-twisted-leaves-some-tips-curled-down-phchart.jpg
yes very minor, but i want to 1) nip it in butt early, 2) learn from mistakes regardess of size, today is ph tap water day then nothing tomorrow so i'll let ya know how it turns out i've been doing 300ish first week 500 second-third 750 third-fourth but tap water is around 180 plus i heard botanicare increases ppm too much to get accurate reading so was more so following instructions on bottle, minus a bit because i am using additives (im using so many diff companies btw) i find if i add 5.8ph water i get 6..1 run off, do i just need to run more water through?
Yes, Coco is considered soil-less, more less a hydroponic hand feed medium. http://boards.cannabis.com/attachments/plant-problems/281235d1325194867-brown-spots-some-twisted-leaves-some-tips-curled-down-phchart.jpg
PH your water down to 5.5/5.6 and water. Ca and Mg doesn't bind well with Coco, so make sure you use Cal/Mag.
okay flushed with tap water 5.8ph intil run off was 587 ppm hanna runofff was same ph also.... hopefully will bounce back up? or should i be flushing until around 200ppm
and run off ppm is what's important for coco right? not the mix itself? but the runoff? or both? im trying to understand why there's such drastic difference while some plants seem like theres absolutely no buffer... dwc you just write changes and if it goes up its too strong, is there a way to do this with coco?
Study this ph manifesto: https://www.google.com/search?q=ph%20manifesto&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-USfficial&client=firefox-a&channel=np&source=hp It's got an excellent section on Coco.
Ppm's are good to measure, and yes it's the run-off ph that tells you which direction to proceed if plant need a bit of correction.
your link doesn't work, takes me to google results, also, if run off is like half of what water jug res is what does that mean? i need to run more water jug res through?
