First let me say hello this is my first post and my first time growing, and thank everyone in advanced for the help that I will receive. Ill start by giving some info on what I have going on.<br /><br />homemade grow room Dimensions are 4' long 2' wide and 5' tall<br />Lights- 2 KingTM 300W full spectrum LED lights 1.5-2 feet above plants<br />2- 5 gallon DWC with 6" basket<br />Use 3.5 gallons of distilled water in each DWC bucket ph'd to 6.3 and 0 ppm tds<br />Change out water every Friday<br />Nutrients are fox farm (Big Grow 7tsp and Big Bloom 4.5tsp and 3.25ml of cal-mag) in each bucket<br />Climate is 80 degrees farenheit with 50% humidity<br />Crop King Seeds CB Dutch Treat Femenized<br /><br />This is week 2 and the first week I just used distilled water with cal-mag added<br />Week two I started by adding the nutrients a little less then the recommended dosage casue plants looked a like fragile and slow to start. But 4 days ago these plants started to take off and yesterday I noticed on one of the plants that little yellow and brown spots are starting to form on the first fan leaves. Please help I have done some research and I'm pretty sure that its a calcium deficiency but need some expert advice. The cal mag bottle says to a 1ml per gallon of water and I added 3.25ml. I added some photos please help and if you need anymore information let me know and I can get it.<br /><br />Thanks Sent from my SM-N910V using Grasscity Forum mobile app
They look great. Leave them alone. Most people kill plants with too much care Sade's outdoor Bigfoot territory grow
Thanks guys but now I changed the water reservoir a couple times and the plant took off with 1/4 strength nutes and 3.5tsp of calmag.
You're on your first grow - and yet you can tell that this brand new seedling has a Ca deficiency? That's pretty good. J
