curling leaves question

Ok Latewood, so as I go through this, I'm just going through all your posts and responding.

I looked and my stems are quite reddish purple, especially in comparison to my soil plants. There aren't any blotches like that under the leaves, though. However, I just noticed that one leaf is starting to get some blotches that appear to be dying, it looks like the clorophyl is just leaving the areas and they're drying out.

As far as the ph, I've been trying to keep it just barely above 6.0 now that you guys have been talking about magnesium defficiencies. I have a digital ph meter, so I'm measuring accurately.

As I said about the nutes, I don't think I'm over fertilizing as I'm not getting burn like I did on a soil plant that I over fertilized. My Tiger Bloom is a 2-8-4. I could mix that half and half in the res with the Grow Big as you suggested.

The silicates are to provide cell wall building blocks and assist in mold resistance. I've read that there's generally silicates in soil plants, however hydro plants generally lack it unless it's added to the mixture. However, it doesn't seem that anyone has really shown that it has a definite advantage.

As far as a flush, would I just run clean water through my res for the full day? Thanks again for your help.

Oh yeah, should I move my 400 watt HPS up too?

ok yeah, I've definitely got some cripsy leaves now :-(

I think that 50/50 mix will get you by...What kind of lighting are you using, and I really couldn't make out your system. What have you got rigged up? thanks for the thanks, makes it worth while. lw:smokin:

Ok, so should I flush my system for a day with clean water right away? Or just add some tiger bloom? Or start a new solution with tiger bloom?

Here's a picture of the lighting system. I raised the light about 4-5 inches tonight.

PS I would strongly advise you get some Pro enzyme's...either the HYgrozyme or the Sensi-zyme...You use about a 1/3 less Hygro than sensi-, but Hygro costs 2x as much...I use Hygro after trying sensi-zyme...I get gooeybudz, so I keep using it! Liquid Karma won't hurt either...If I added just one additive...
It would be Liquid karma*...Oh yeah, you got Earth Juice catalyst. Looking forward to following your grow to see your results;)

*remember, when using organic nutes/additives you cannot use hydrogen PeroxideH2o2 to kill bacteria...it will kill 'beneficials' :p as well as 'cooties'!!!:(
so, instead, we use the above products and this allows us to use organic additives,etc...

In answer to your question about flush; Again, I hope anyone else that knows better, chime on in, anytime:) anyway, I think that you since you have a flat-out deficiency...You really need the phos', so I would get fresh water mix that 50/50 solution 1/2 strength, adjust ph to 5.8 and let 'er ride.:thumbsup:

gotta go take some pix of new ops...you all are going to love it:D :) :cool:

Ok, I just added some of the Tiger Bloom last night, at half of the weak strength without refilling the res. I figure that since I'm already running the solution weak in order to be safe, it won't hurt to just add some bloom nutes. I'll keep an eye out for nutrient burn, I know what that looks like as I burned my soil plant a bit a few days ago and had to do a flush. I'll keep an eye on the new growth to see what happens and keep you posted. The roots are still doing great and growing like crazy!

I also keep a thermometerr right nearby and is doesn't go over 82.

Leaves curling up is a sign of stress...

Maybe it´s the lack of nutrients.. in soil you always have more nutrients and spores than could ever get in Hydro substrates.

the whole point of flushing is too rid the plant of nutes and toxins, your plant omit toxins in the water as a discharge...I think that is how it goes. Just adding something might work, but in my h.o., you just wasted nutes; And you don't know what's in there. You see, only with a fresh batch of nutes, will You really know what you got.

If you think you are wasting money...Do what I do. Think of how much that 'sakoweed' is gonna cost, if you lose'em.

I think you will find that any experienced grower will tell you; In Hydro if you are having nutrient or res problems....Emergency...
Danger, Will Robinson!, FLUSHFLUSHFLUSHFLUSH...What about the Epsom salts you added? Did you really need that in your res? It's like
fixing your car's electrical system...1 part at a time. Goodluck lw
