When should I strt giving my plant nutrients its a white widow an its in a 5 gal bucket an imprety sure the soil had nutrients in it already Sent from ........ using Grasscity Forum
Get it out of the bucket and into a smart pot(7 gallon or bigger. Bigger is always better) If you are using soil with nutes already in it I advise looking at the brand and telling us about it's nute levels and if they are time released nutes. Also chances are you don't have perlite... get some.. Then I would say get some promix HP or Fox Farms soil.... For nutes during veg I like Fox Farms(big grow, tiger bloom, and big bloom, kangaroots, and microbrew) For flower I like to use (tiger bloom,big bloom and beastie bloomz)
When it will need nutrients depends on what type of soil you used. It probably does have some nutrients, most do but without knowing more about the soil anything is just a guess. Most bagged organic soils will support the plants for three to five weeks of good growth. How much the plant uses and how fast is also a variable. A small plant that has been under one CFL for four weeks is going to use a lot less of the available nutrients than a much larger plant that was grown with proper lighting. Learning exactly when to start feeding is one of those experience things that you get by using the same medium, environment, lighting, and strains for a while. Three or four weeks however is a good starting point. Beyond that watch the plants, nitrogen def usually shows first in veg and is pretty easy to identify by an overal even change of the leaves to a lighter green color.
If the soil had nutes, you won't need nutes at all...and could kill your plant with nitrogen burn if you used them, potentially. Soil with nutes is inherently dangerous....if you're smart, you'll never use it again. Reason being nutrient ompregnated soil has bits of water soluble dried nutrients mixed in. They work by dissolving when they get wet, and being taken up by the root that drinks from that water. Problem with that is that it means the water closest to the node is too strongly fertilized, water farthest from the node, too weakly...so you easily burn some roots while starving others....you can literally have nitrogen burn and nitrogen deficiency going on in the same plant at the same time. Part of indoor growth is control of variables in order to get the best possible quality and yield out of conditions far inferior to those the plants developed to grow under. "Natural" organic soil (no nutrients or incompletely composted biologicals) is 100% neutral. Mixed liquid nutes and mineral additives give you complete control of ratios and amounts, and delivers it uniformly to all roots that have access to the water at all, not just the water that's passed over a nutrient node and dissolved some of it.
Agree. Top-dress once between veg and flower and that's more than enough to finish a grow. Mix some glomus intraradices into the rootzone for a nice boost too.
Once veg ends I start a mix of light beastie bloomz and a Miracle grow 6-1-1 for a few feedings. Replenishes a bit the the Nitrogen and works the plant into her desire for more P-K.
Organic or not doesn't matter...impregnated with dry nutes is impregnated with dry nutes. Plenty of organic soils out there that blatantly tell you they have nutes for 30 days or 60 days or even 6 months. Problem with pre-nuted soil is, exactly as I stated, dry nutes aren't controlled nutrition, and if you add nutes, you run a high risk of creating burn. With experience with a particular soil, you can learn when it is and is not OK to add nutes, and how much/when...but even then, it's a risk. Dry nute soil is a bad idea, period. You need to know MORE, not LESS to use it well.
Your question has been answered, considering the amount of information you gave. If you want more specific answers then you need to provide more details about your grow and some pics would really help too.
