Thoughtful reply! Thanks

Some seem to claim that if your res PPM is dropping then the plant wants more food. Is this always true??

Thanks for the help guys. So in your opinion even though I'm feeding at a fraction of almost every recommended level i can find (Most people say way over 500ppm for a plant in full veg) this particular lady can't take it. I would just hate to stop all the food to find out it was a deficiency of...

Im a couple weeks into main-lining in dwc. My ppm with GH trio and well water is pretty low and stays rather stable around 550. The leaf tips have been curling under for a couple weeks and I thought it could be due to low night temps in my basement. However now the tips of some of the new growth...

So Im about a month into my first dwc grow. The strain is purple haze. Using my well water which is 75ppm. I had upped the GH flora trio at 3-2-1 to 1000ppm with cal mag at 2mL/g and the largest fan leaves began turning yellow and had tips that started to curl down (Pic 1). The new growth at the...

She's 4 weeks old from seed. Had been vegging well at 1000ppm with flora trio then i upped it to about 1100 and this started happening. I also realize now that I planted her low in the cup. Roots look good. Any advice?

Thanks doc! Just a little confused bout what you meant by until you reach the total that the res can hold. Do you mean water or ppm or..sorry, the rest i totally understand!

its easier to see today

So my first two leaves showed what people told me on here was prob a cal deficiency. I added cal mag and started the flora trio in equal parts of each. Got it up to 400~ ppm and the new growth looked green and great. Then I added about another 100 ppm of nutes and the tips showed brown signs...

WELL i upped the nutes to about 500ppm and a day later the tips of the new leaves are turning and then this morning I began to see brown spots move down the leaf from the tip. Is this nute burn? Is it still a calcium def?? I need some help guys.

OK so she's now 3 weeks old. The first fan leaves still look shitty but all the new growth seems fine to me. I have added cal-mag at half the recommended strength and am using the gh flora trio at about 400 ppm. How do you think she looks?

Is that not too high for a young plant? Cuz I'd definitely like to add more nutes.

and the pH is 6.2 straight from the ground. Its the best tasting water I know of.

like 80 actually

So how far away from a young plant like this would you put a 400W MH? Its in a cool tube with a capable inline fan so heat isn't a big factor.

Thanks. I think it's a good idea too.

I currently am running a single outlet 3.2L/min pump in a 3.5Gal bucket. Will upgrading to the 7.8L/min pump make a worthwhile difference?

Interesting, thanks. What do you think about just adding some cal-mag to my well water?

Hmm interesting..that does look similar. I thought cause I'm using my well water it would have some cal. But it's only about 80ppm so thats not very hard at all.

so you don't think this looks like nute burn? (I don't either)
