Hydro Questions: Help!!!

Sorry I am not going to be too much help but... this is the lucas formula for growing which is gh flora series micro and bloom only, 5ml micro, 10 mil bloom per gallon while vegging start with 50% solution with seedlings and go up slowly as they grow. Flowering is 8ml micro, 16ml bloom per gallon.
There are two ways to work with this formula:
1. Top off the reservoir daily using a pH corrected water solution as required to maintain full reservoir level. After adding back an amount of water equal to the amount of your reservoir capacity you should change the reservoir and put in fresh solution.
2. Top off the reservoir daily using a pH corrected 100% strength nutrient solution as required to maintain full reservoir level. Continue to use this nutrient solution without dumping the tank unless the PPM rises above acceptable levels.
Between vegging and flowering should dump the nutrients and flush with clearex to kill the salt buildups then go to the other feeding schedule.

Some good additives hydroguard(good bacteria), clearex(flushing agent), b1(kinda like superthrive), phup, phdown, bushmaster(stops vertical growth increases flowers by up to 30%, damn expensive) and 35% h202 I use this for cleaning and such(don't use with hydroguard will kill bacteria).
Pretty much everything for hydro can be used for soil.
Some good sites: bghydro.com, cheaphydroponics.com
As always I can't take credit for any of this.

Oh two things added. I hear that Advanced Nutrients were tested growing cannabis. The Lucas formula is only supposed to be used with RO or zero ppm water.

It turns out that the ppm level is around 1200 in my current setup...but the seedling seems to be doing alright for whatever reason....I will get it onto a proper diet soon, but i need to know one thing...my tap water is at 200 ppm naturally...should i buy the "micro hardwater" to compensate for this? I was thinking yes, but I am not sure.
one more question...
should i ease the pH up to the right level or should i do it all at once?

You adjust the ph at once. In other words, keep on adjusting till you get the right number. If this is your first go at ph, be prepared to throw out a batch.

here is a revised pic of the plant i originally thought was doomed for. Mmm, looking good. It does look a little raggidy because i nearly killed it early on...
but besides that, why is it a little droopy?

I should be switching over to actual nutrients soon...Hooray! Plus I'll be putting it under mh. Hooray! I'll post pics when the plant is exploding in growth. :thumbsup:

this mo fo is growing nice and quick...i think hydro is more exciting and enjoyable for that reason...so far, so good...i have yet to switch anything to an improved set up...

4)besides the gh flora series, i was looking to get liquid karma, megagro, and also some superthrive... sound complete enough or should i be looking at any other products? (ill think about bloom bud and big bud when the time comes, for now, they are babies)
5)can any of the previously mentioned nutrients be used for soil grows with any success?

1...do the math...example:1 qt/liter ml per gallon (5) times res capacity (18);
So, 5x18...then divide that into 1qt/liter...So, 1000ml divided by 90ml(5x18)=?

That is how many res changes you will get from that size bottle;)

2...7-10 days. Watch your plants...add ph'd ROwater in between res :) changes. this allows for the leaching of some salts before next dose of tea.

3...Don't start putting alot of "CRAP in your res...It will only tangle in the 'root system'...:(

4...If you get Liquid Karma, you don't need Superthrive, but I have both and use Superthrive as a tried and tested stress reducer. If you have three part you can double your bloom nutes to enhance flower...I would add Calmag+ if you use ROwater, because RO removes the calmag in your water...And get some Hygrozyme for the enzyme protection of your res...If you cannot afford Hygrozyme...then buy Advanced Nutrients Sensi-Zyme...keep in mind that You use about 3parts sensi to gallon///Hygrozyme you add 2 parts to gallon; In comparison to amount used per/and determining cost per dose...I switched to Hygrozyme(organic; also, if that matters)...you have to read up on both and make the call.:cool:

5...yes

hope this helps...I haven't stopped in too much, because i have seen that you have many advisors...peace.lw

this tidbit of info...I for got to mention...Since you asked about how long nutes will last; this might help.

3-part
I dont' use much grow...A liter bottle last me a couple grows...
Micro a liter per grow...
Bloom, You use alot more bloom than the others, because generally People are not "Vegging Long" on Strong nute formula's, they spend more time on the flower photoperiod. I buy a gallon of Bloom

Liquid Karma...Buy a gallon...same with Calmag+ (you will love this stuff and want to use it, so this advice will save you a bunch of money(buying little bottles @3x the price))...Hygrozyme fits in this category, if you are going to have large perpetual grows. you still save a wad of cash, if you buy can afford a gallon. lw

water log or roots gettin to big
