Nutrients??

Alright, well im a first timer and i was wondering when to start feeding the plants nutrients?? My plants are about 2 1/2 weeks old. The guy at my local hydro shop said to add them now, then i seen on here that people say thats to young? So like someone thats not experienced i add some nutrrients and now on one of my plants i see a yellow spot! They were doing great without nutrients, but if someone could give some advice it would be great, and also how often to feed them when i do give them nutrients?

just a suggestion. get some dynagrow 7-9-5 at your shop and use one half teaspoon in a gallon of water, I think it is. instructions are on the back. and water with that. let the soil dry out some and then water with the same thing again. it's a complete fert and should work for you. there are other choices, like supernatural brand terra, for soil, but it's more expensive.

So if im understanding correctly, i use the fert everytime i water?? I used sensi advanced nutrients the first time cause the guy said to. Thats for veg and flower or just veg?

if your doing soil, its "Nute water, ph'd water, ph, water, repeat"...make sure to wet the whole medium(until you see some runoff)

Thanks for the help guys, i will post pics soon and let you know how it goes, by any chance is any one familar with those sesi advanced nutrients?

Look, before you go spend money you might be able to use on quality seeds instead, listen to me a little bit.

I use Fox Farms Ocean forest exclusively. I clone in rockwool. I do not give any nutes at all in vegetation, instead I just keep increasing pot size and adding more soil. That is good for 3 weeks of 'food/nutrients' for my plant until the next repotting.

Yes I do give some very specialized stuff in flower. Molasses once a week and some Ultra Snowstorm once or twice in the whole flower cycle.

I have posted pictures here at CanCom with my plants with buds the size of my forearm. I do not buy into these feeding schedules at all. Many of the really good growers really do not not give a lot of nutrients. Some do. So consider the alternative I just offered.

Thanks for the help bro, one question for you, how often to transplant?

Washougal...

After listening to you speak about only using repots to feed I tried it. Was able to get through the entire veg cycle with no nutes. On one plant I used a small amount of FF nutes and the growth difference was very noticable. So I dont know why you say you dont "buy" into the feeding schedules. They definitely work but your repot method is an alternative.

The growth is a tad bit slower than if you use liquid nutes. Also repotting in flower can not only be difficult with big heavy plants, it can also stress out some nanners if not done with alot of care.

I will say one thing though, you definitely have the method down. I have seen your threads and your buds. They are great.

GetThis, I think WW was referring to an actual schedule - one of "water, fert, water, fert." That kind of schedule. I think he's right to, as there's no proof that schedules work. For all we know it could be adding fert on top of fert and we don't know how the plants are absorbing the new stuff versus the old stuff. I used to use the scheduling idea and I grew good with it but at the same time, I have no proof that it really worked. I don't know if the plant would have grown the same without a schedule. Nature doesn't seem to use much of a schedule and plants grow just fine. But indoor growers are impatient and want plants to produce now, without waiting.

No, not necessarily. I'd use it once or twice over the span of several weeks, and one more shot of it if it looks like the plants have a deficiency. The fert is designed more for veg, as there is also a flower version, but I bet you can use one fert for both. I have no knowledge of advanced. The guy at the shop told you to use advanced? If that's what you have then maybe you should stick with that. Just don't use too much, eh?

pp, thanks for the help bro, and everyone else, i realld do appreciate any help. I think i will do the water fert water fert and see how that works

I'm familiar with the Sensi 2-part nutes if you have questions about it I can try to answer them and if I can't I know who can.

As far as when to start feeding them - if the leaves get pale and turn yellow you waited too long. If the tips burn you started too soon/heavy. It varies from strain to strain how quickly they need nutes and how much you can give them to start.

I always start off super light, like less than quarter strength and build up slowly from there. Obviously you don't want to try to do it wrong, but just remember every mistake teaches you more about where the limits are.

A lot depends on the nutrients in the potting mix, and the additives the gardener uses.

I was using an organic brand by Dr. Q called Filthy Rich potting soil. It was a blend of peat, forest humus, worm castings and perlite, and I'd only have to give half-doses of nutrients during the growth stage. (at least for sativa dominates...indica's got a normal dose)
Was beginning to think my seeds had spoiled or that my water was toxic. Then I re-read the ingredients list on the bag. Dr. Q changed the mix, and have excluded the forest humus and worm castings. Wish they would have pointed-out this different formula, but I finally figured-out what was causing my yellowing and stunting problem(s).

The point is...FFOF is a moderately "hot" blend that provides most of what a plant needs for the early developmental stages. Not nearly as aggressive or long-lasting as Miracle Grow soils, but it can sustain growth for a while. Transplanting provides the 'bump' of nutrients necessary for the rest of the growth phase.

Usually growers wait till the 4th or 5th set of true leaves to start giving half-doses. Check online for their weekly feeding schedule. (on the company website)
Don't overwater. It causes yellowing, stunting and brown spots.
