Hydro question on feeding

[turksteelman]

My space is 8x11 feet or so. I plan to use a 5x5 foot square screen at the most as I only have 1000w HPS for flower.

turksteelman Reviewed by turksteelman on 01-08-2013. Hydro question on feeding Have used FF soil in the past. Going to use Sunshine mix #4. I will be in veg and flower in 3 gallon pots. Growing 6 Liberty Haze under 1000w. I am totally unfamiar with where to go from there. I know that I should first use Calmag in the RO water. I will be using Foxfarms grow big for veg and big bloom for flower along with Tiger bloom. What kind of feeding schedule should I have? When using a soil less mix I would assume I need to fertilize every day when I water them. What would that look Rating: 5

Awesome. I use a 400mh for veg, and a 1000hps for flower. i think you can go 5-6' x 8' screen. Not only will a 1000w cover that space; You can move it back and forth daily over grow and get great results.

i would run it like a soil grow my friend...wait for them to show you what they want..

calcum nitrate is where it comes from.......

I did not think that Nitrogen was an ingredient in clamag; So I went to the Botanicare homesite. From the Botanicare website: Ingredients of calmag 2-0-0: Cal-Mag Plus contains: calcium, magnesium, iron, boron, zinc, manganese, molybdenum, copper, cobalt, iodine, beneficial vitamins, twenty essential amino acids and select botanical plant extracts.

To be honest; Now that I read all the ingredients. this is more of a Micro formula. IN the greenhouse we use Calcium Nitrate, and Magnesiuim sulphate, so I don't add Calcium and Magnesium to my custom Micro mix, but, this is
basically the same ingredients in most micro mixes.

My Micro ingredients are Chelated Manganese, Chelated Zinc, Boron, Molybdate, and Chelated Copper. Calcium and Magnesium are sipplied as mentioned above.

Still don't know where the 2% of Nitrogen comes from on the bottle label.

Anyway; I don't believe you would need to worry about that as long as you are lowering the amnount of part A or the Nitrogen in your mix, as you should be in flower.

Thanks, but I do not see Calcium Nitrate listed. I make my greenhouse nutrient solution from scratch and buy 50 lb. bags of Calcium Nitrate and other minerals.

So where do you get Calcium Nitrate in that list of ingredients. Just wondering. Sorry for taking the thread sideways

Hydro grows don't use potting soil. They are soiless grows. You just use something to hold the plant, like hydroton, rockwool, rapid rooter. When growing in potting soil let the soil dry out some before you water again. Certainly don't water every day. You might not have to fertilize at all for the first week or so. You might want to ask the maker of the soil if there is fertilizer already in the soil and about how long it will be good for before you have to fertilize.

a good rule of thumb with a soiless medium like sunshine mix is feed-water-feed-water. Just alternate them back and forth, making sure that all solution given to the plants is within proper ph range. If you see signs of overfertalization, tone it down a notch. Be cautious with the cal mag when you get into flower, the extra nitrogen it provides will sometimes give you the dreaded "claw" on your buds. The thing to understand is that the plant will tell you what it wants. It just takes a while to learn each strain.

Good response, although reading your post I wanted to comment for other newbies.
I got the "claw" effect when I transferred a recently rooted clone into 5.6 pH de-chlorinated tap which had no nutes added at all(40 ppm). There was no nutrient or pH changes, although, there was a temp/humidity/airflow change moving to the new environment.
Just curious if your experiences also had changes in temp or humidity. I'm sure that my plants had no excess nitrogen, just open stomas and more airflow. The 'claw' effect can also because by other stressors.
