Hey guys. Thanks for answering my question watering/feeding in Radicle Bags on episode 920. Its been a few days since posting that and since i have gotten my Recharge in and mixed a 1/2 tsp with a gallon of RO water and gave it to my ladies. I haven’t really been able to see a difference in the past 48 hrs, but i also cant see my roots so I have no clue whats going on. They aren’t looking to healthy though. now I have been worried about nutrient deficiency in the medium. I use Advanced nutrients sensi coco grow/bloom part A & B it has cal/mag in the solution and wondering if they are getting enough from it or maybe my coco (not sure if it’s buffered.i used Vigoro coconut coir) I’ll post some pics of them from today 10/18. I have been watering them about every 2 days now and I used Recharge 4 days ago and again this morning with AN grow part A ans B. Today i used 2 ml of A and B along with 1 g of Recharge. I only use 1/4 strength for my synthetics because I was told and have seen from many Autoflower growers that using 1/4 strength works best and its harder to burn them. What do you think? Anyone grown autos and used full strength Advanced nutrients with results? I’m using recommend dosing on the Recharge. It says 2.5 g for a gallon so i figured if I’m watering them around 2 qts (half gallon) for now then 1 g of Recharge should suffice. Is there a way to check your cal/mag?? By the look of what i have Now what do you think?
I keep a journal so i have notes on all my ppm and dosing for every grow. I have been watering every other day for now and ppm is between 450-500. Is this too low?
Thanks
Sweet Question man you may just need Cal mag. I was also wondering about needing cal mag with there coco line base nutrients. I just picked up everything for a grow and I got The coco AN Conni hoping I wouldn’t need the cal mag bottle. I always needed it with other base nutrients even regular sensi bloom and regular GMB. I needed cal mag when I used Maxi bloom also.
I was looking over an article talking about cal-mag deficiency in cannabis plants using Blurple lights. It was from the cheap home grow podcast on youtube and it was stating that the cheap LED lights like I am using can cause the plant to show cal-mag def.. Ever heard of this? I feel like that is for Guru to answer on..
Also I havent had any issues before in my last harvests and this usually happens everytime i start a new grow in coco. for the first 3-4 weeks they will show some signs of yellowing or started to look like nutrient splash on some lower leaves. This grow i am doing I used a 8qt bag of Vigoro coconut coir from Home Depot and and added perlite, mixed it up and dropped it in the pot. the previous grows I did the same but would rinse the coco several times washing any impurities off. after rinsing the coco I would add the perlite as well as a 2x strength of Sensi Grow A and B to a 5gal bucket and let the mixture sit overnight. the next day I would drain the bucket through a metal strainer and then placing the media into my fabric pots where they are now ready to be used. I flush the pot with 1/2 gallon of RO water and check the runoff- it was at 700ppm from my notes- this time i didnt do it so maybe that is why im getting this deficiency? according to Advanced Nutrients you DONT need anything other than this product if coco?? what do you think?
Coco nutrients will contain the extra cal mag necessary. Led lights don’t produce ir or far red which would raise the plant’s leaf temps. This allows the plants to increase metabolism and take up the harder to get nutrients like magnesium. Im thinking you got some possible root issues from a low ph or salt buildup. Could be the salts from not washing the coco or from the medium drying out and leaving salt that way. I would flush check runoff and then follow that up with a nutrient dose. 500 is enough especially at that size. Coco usually needs to be watered more often.
Thanks @justcoolin ill check the runoff ppm and hopefully i havent messed up too bad yet. I am noticing only stunted growth and some lower leaves yellowing a small bit. Thanks for y’alls help.
I just checked the runoff ppm eith my meter and its reading around 1550-1600 ppm.. I have only watered with the highest ppm maybe 600.. Is this my issue. Should i flush? And if so should I wait until the next watering and just water with 0ppm water and PH around 5.5-5.8 with no nutrients? If I fucked up bad enough i can always restart. I have plenty of seeds for now. Just need to figure out how to properly rinse and buffer my coco i guess. I had runoff at 600ppm before adding it into the pots. But to double that im not sure how ir did it.
Do you water to runoff?
Yea after i water i will get about 20% runoff sometimes more. I dispose of the runoff so its not sitting in the trays as well.
Keep adding til it comes out the same pH and ppm you are using for a clean fresh reset.
