I'm growing in coco with a layer of perlite in the bottom of the solo cup under 8 bulb T5 light using Botanicare CNS17 Grow 3-2-1 and Liquid Karma and Silica Blast (all Botanicare products) watering every other day started at 150ppm - then 2nd watering 200ppm - then 3rd watering 250ppm keeping ph at 6.2. I'm growing using Hempy Bucket process. This is my first grow and I've read articles online until I am going blind. I could really use the help of a veteran grower. My gut tells me something is wrong but alas I have no idea what it is or how to fix it any suggestions will be greatly appreciated!
does the soil seem to be too watered? the leaves are drooping a bit and some seem to have been ripped off or eaten by something or did you just cut them?
I received them as clones in rapid rooter with some of the leaves already cut I've been getting mixed messages on how wet to keep the coco some say let it dry out then put a saucer under each plant and let it fill with overflow out of the hempy hole on the side of the cup and when the plant can leach it all up in 24 hours I should be ready to up pot. Does this sound right I sure could use some advice. Others say that the coco should never be allowed to dry out that it should always be kept moist. I have become dazed and confused here's hoping help is on the way!
sorry didnt see the reply, i've been keeping mine moist letting it dry not completely and i'm doing coco too, and don't water a bunch everytime only flush once every 4 weeks, look for the signs of under watering and overwatering
that small water more like 1/4 dose. Also could be Mg issue if its fresh coco, so adding a little extra Mg couldn't hurt. As long as you have proper drainage then it is not overwatering. Most likely cause is your nutes are still to strong.
If you have that much perlite throughout the whole cup then you'll have problems. I recommend 100% coco W knat knicks. Perilite starts to turn green after time. Not the kind of fungus you want in your garden. And the flies are attracted to it.
first, 6.2 is like the absolute top end of the spectrum for coco...i'd try an bring it down to 5.8, maybe as high as 6.0...6.2 can do well in later flowering as P becomes more important, but for now, keep it lower... looking at them, i'd definitely say u need to be adding a calcium/magnesium supplement...i've never had issues with calcium deficiences myself, as it was never an issue when i did organic soil grows, an i've been using botanicare's calmag + since i started coco...but IIRC that looks like a calcium deficiency for sure... i'd almost say they need more nitrogen, but i'm pretty sure calcium will lighten the green in the leaves like that as well...1/2 strength should be a low enough dose, even if it wasn't, i don't think 2 weeks is long enough to build up enough of an excess that ur gonna see that kind of effect...definitely would lean toward a calmag supplement... also, for the perlite, u'd be far better to mix it with the coco...i run a 60/40 mix of coco/perlite an it works fantastic...i have noticed the little green tint on some of the perlite at the top, used to see the same thing in my soil grows...but top layering with perlite is not only more likely to cause the green slime, but it's completely unnecessary...coco is fantastic at both water retention an root oxygenation...u can grow in 100% pure coco an have amazing results... watering wise, u can water them every day...once u know the root zone is established in the pot, u will need to water them every day, an if u let them get big enough, u will need to water them twice a day...maybe three times a day in flowering, depending on pot size...but once a day is not enough to overwater a plant in coco, provided the roots have taken hold...
