I think what Stinky is saying is to get and use the right equipment for the right job. Lame is right......good luck growing anything with the stuff you have now.

relax man, no one is trying to insult you, try and understand that you're not the first newbie to pose these sorts of questions. and i don't think anyone is telling you your stuff is shit, the thing is, it's really obvious you haven't done your research. people don't want to help people too lazy to help themselves. listen to Stinky, she may come across a little gruff but she knows her shit, and she has helped, and continues to help, newbies like you and me. if you can get her to coach her you will learn a thing or two
Orchid food is for orchids, potted in orchid mix.
Hydro pot food is for pot potted in hydro.
They are buffered very differently, and have different relative nutrient levels. You'll be fighting with pH and lockouts if you use the wrong fertilizer.
You don't absolutely NEED an EC meter to grow weed; I've done without on my crappy city water, but if you can't play mad scientist, you gotta play assembly line dude... take the parts that someone else tells you to use and assemble them EXACTLY as intended. Just as you can't put a small block in a Volvo without modifications and a good understanding of the whole system (but OH HOT DAMN is it ever worth it OMG), you can't grow hydro with soil fertilizer unless you have the tools to make the necessary adjustments.
So in your case, match like to like. I strongly recommend the Canna Aqua series as being virtually impossible to fuck up if you follow the instructions on the back of the bottles.
its for hydro.
I just want to know whats wrong with the leaves, can no one tell by just looking?
I can't find it in the Growers Bible by george cervantes, looked all over the net, nothing similar to lime spots turning brown eventually and then crisping up.
this isn't the official form from this site but it would help people help youQuote:

In order to better help you diagnose your plants problems, please answer the following questions as best you can. Put the answers in a post in the Sick Plants & Problems forum; give as much detail as possible.
Are you growing designer genetics or bagseed?
Are you plants from seed or clone?
How old are your plants total?
Are your plants in flower?
How big are the plants (in height and # of nodes)?
What type of medium are you using and what is its makeup?
What size planter are they in?
Chemical or organic fertilizer?
How frequently do you water and how much do you use?
How frequently do you feed them and how much do you use?
Have you seen any bugs in your garden?
What size light are you using?
How big is the room they are in?
Do you have ventilation?
Are you growing designer genetics or bagseed?
Bagseed
Are you plants from seed or clone?
Seed
How old are your plants total?
26 days
Are your plants in flower?
Just started 12/12 a few days ago
How big are the plants (in height and # of nodes)?
About 6 inches tall, 5 nodes
What type of medium are you using and what is its makeup?
DWC with one airstone
What size planter are they in?
5 Gallon
Chemical or organic fertilizer?
Chemical
How frequently do you water and how much do you use?
Sits in water
How frequently do you feed them and how much do you use?
at first 5 tsps of 20-20-20 fert, now after flush, 1 tsp
Also, added H202, Superthrive, 1 tsp of Epsom Salt (now)
Have you seen any bugs in your garden?
no
What size light are you using?
600 Watt HPS 32 inches from tip of plant
How big is the room they are in?
see picture
Do you have ventilation?
Yes, a lot.
Started out with 2x 65 Watt Fluorescent lights (see picture 1)
Started on 17/7 Light cycle for 17 days,
Switched to 14/10 Light cycle for 6 days
Switched to 12/12 Light cycle for 2 days now.
about 3 days ago, I woke up to a fan that had fallen on top of the smallest plant (the one on the left behind the empty one)
pH is now within 5.5-6.0 probably about 5.8 or 5.9 Tested twice with strips to confirm.
Bought some 0.25 increment pH strips, these strips show the pH to be at 6.25 whereas the other ones say 6.0 but probably lower.
these new strips are for urine and saliva testing, don't know if that will affect it's ability to read the pH of water...
Why did you add all that Epsom salt?
How much superthrive did you use?
20-20-20 is incorrect for any life stage of cannabis. At 1/5 dose, you have a 4-4-4 fertilizer with too low levels of micronutes. You need a set of cannabis specific ferts. In soil, you have more wiggle room. In hydro, you don't.
Move that fan AWAY from the plants, and point it away from them- it's drying them out. You can see leaf edge curl.
What's with the light cycle switches? Is it possible to maintain dark period in your grow space?
Put them back on 24/0 light. Never flower a sick plant. It will more than likely die before harvest. And 5 nodes is much too small to flower a from-seed plant. You should wait for sexual maturity first. I find that happens around 8 nodes. You'll have to wait and see.
epsom salt: 1 tsp in 5 gallons
Superthrive: about 1.5 tsp in 5 gallons
20-20-20: 1 tsp: 1/10th dose 2-2-2 (superthirve should make up the micronutes?)
No fan is directly pointed at the plants, the plants were overwatered and the ridges were curling upward (sign of overhydration?)
It's dark at night?
I don't have time to veg them any longer, this project must be completed before beginning of july to mid july, wish me luck, hope this works out.
5 nodes is too small to flower from a seed plant, however some people do 12/12 from seed?
You've got a wicked N overdose from all that superthrive. The upper LH plant in the first 2 pics confirms that. Soft, dark green, cupped, lush but dull growth. Did you read the instructions on the bottle? It reads, "a drop a gallon". One drop = app. 1/40 mL. Do the conversion from mL to teaspoons to see how badly you overdosed the plants. Where do you see a listing of the micronutrients in SuperThrive? It's not a micro supplement. It's a hormone, and has a crapload of urea in it as well.
Use a micro supplement for micronutirents. GH makes one for hydroponics.
With all that secondary growth, it actually looks like you'd be okay to flower. Looks like more than 5 nodes to me actually. But get them healthy first.
I am not trying to dis your game, but you are reinventing a perfectly functional wheel. Go pick up the GH 3 part and some calmag and run the way that works. If you cannot afford the $20 USD for a pint each of grow, bloom, micro, and the $15 for a test/up/down pH kit, you should consider growing outdoors, where you can use practically any fertilizer you've got kicking around (not the azalea stuff though). Your electricity costs more than that!
