Help with Coco and feed please

I appreciate the help people . There's tons of usefull information here. I'm just trying not to over complicate my mind. My situation is I have my A and B nutes pk13/14. Four 15l fabric pots and my setup dimed my light to 250. Seeds have sprouted from Coco and about to lose there shell . I have no means at the moment for a pH tester but am seriously considering getting pH strips. I've been told to feed nutes straight away and been told not to for a week . How often shall I water my little girls ? And when I do start feeding shall I start with 1ml each of A and B and work up to added more If anyone could ease my mind I'd be most grateful ,,,,,😁 Just started a diary to give you a better perspective thanks guys and girls Peace

I have exactly the same nutes; cant find anything online on how to use them. Ive seen users mention that they are comparable to canna coco a+b in usage so, ill likely just look up a guide on how to use them after checking the ingredients in all 3 bottles.

yes, it need feed always -- coco has zero nutrients for all intents and purposes. There may be a time or two you irrigate with water only, but the plant is 100% dependent on the fertilizer you supply. what it lacks will be a deficiency for your plant. I'm not super familiar with hornet feed, so i can't say for sure how often or if you should reduce it a bit, etc. When you see some darkness, feed with water-only. Reduce what you use slightly to avoid that in future with that strain. Keep notes on this stuff if you clone plants. it'll save a ton of repeated mistakes. At worst i see a little dark creeping up, and know to pull back, but even avoid that more times than not the entire time. (potentially has catastrophic amount of K and Na like i said, but assuming that's prepared well at this point.)

About the part A and B... follow the instructions... in general you'll add the one containing calcium last, best guess. It has to do with avoiding precipitates as you mix. Look into J.R. Peter's 3-part or is it general hydroponics? or maxibloom that has one too? more than jsut 2 options i'm sure and all virtually equivalent. You don't buy the water weight and pay pennies per gallon. Mixing takes a bit more effort, but I don't have to buy fertilizer for 3 years, lol.

buy 100-pack of ph-strips that resolve down to .1pH for $7. It'll be delivered within a week or less. you don't even need a 100-pack. if your tap water is consistent, you'll get a consistent pH from your fertilizer if added at same concentrations. But, you'll want to know what that is to avoid easily avoidable problems. With hydroponics, you have less room for error with your plant compared to soil. In general, you'll be able to fertlized every irrigation. In some cases you may want to add water only, but you'll want to ph that water to 5.8-6.3 (5.5-6.5). Unlike all the charts i read, i have no problems at 6.5 and tons of problems near 6 and expecially below in coco coir. So, clearly strain matters a bit too. Mileage will vary, clearly. Here is one thing i learned back in October when i switched. Cheap coco coir, like mother earth 5kg bricks, require additional preparation before use, otherwise you will end up with cal/mg deficiencies by end of bloom period or earlier in longer grows. Not all coco is prepared equally. Thoroughly rinsing it is not enough, either. I basically use my cal-nitrate with some epsom salt + vinegar to pH it down. Soak it 2x for 8 hours. I do this all in one day and the second soak i just let it sit overnight for good measure. Cation exchange sites -- simply explained -- the molecules adhere to the coco. it comes loaded with Na+ and K+ ions. you need to get this to a new equilibrium so that it doesn't leach the Ca++ and Mg++ ions with a stonger affinity to those sites out of your irrigations. As you add it, it sucks it out and locks it away from your plant, while releasing all that extra Na+ and K+... really not good for the plant.. .double dosing with K+ and increasing salinity. LoL! Anyway, if you didn't buy good stuff, go soak it 2x in some Calcium and magnesium solution without K specifically. I let it sit for a bit to thoroughly drain. I run my normal fertilized irrigation through it with heavy runoff to "reset" the contents of the coco coir. It should be well-fertilized and good to go at a safe concentration. I'll only use ph-d irrigation the first week or 2 of a seedling/clone until i think it's used up what i've put in, or i irrigate with heavy run-off with fertilizer to avoid high concentrations early on. Otherwise, some coco will cause insanely bad problems. I had a clone take 39 days before it grew vigorously. It had roots, grew a bit, but was ugly AF. Dark, twisted, crap growth. then, after it got through that, it was rootbound due to extreme age for pot size with cal/mg deficiencies late in bloom, lol. It'll ikely survive, but you'll still run into problems later. i use jacks - 1 part is cal-nitrate. So, i should never see a calcium deficiecny, lol. (or rarely). If it's prepared well, i never do since that first bad experience. Actually, took 2 grows. I throroughly rinsed it without a soak the second grow.. thought i was smart...

Well if you are serious about growing in coco for yield; Go to this site https://www.cocoforcannabis.com/ And to Amazon to get this book : https://www.amazon.com/Coco-Cannabis-Growers-Dr-M-J-ebook/dp/B07G9LR4W2/ref=sr_1_1?crid=3UB3FKPR64RNB&dchild=1&keywords=coco+for+cannabis&qid=1589241122&sprefix=coco+for%2Caps%2C271&sr=8-1 You will not be disappointed, it is my coco growing bible.

Do I add part A and B together through veg and flower i.e in same water feed ? Also will it need any feed at all at this stage Thanks buddy

without ph it becomes very difficult on coco, you have to keep it unsigned between 5.6-5.8

Forgot to say they are auto 😁
