Are lettuce and cauliflower are they really of the cannabis family? I have been told that they both contain small amounts of thc? is this true or are they even partialy related?

Always good reading on this site.

Of course lettuce has thc, thats why I eat salads all the time.

Poem for the day:


If you kiss your honey,

when her nose is runny,

and she thinks it is funny,

Its snot.



Drain the tank entirely, look for dead roots, and remvoe them, don't be afriad to remove too many.
Re-fill the tank with cold water, give it half gallon more than normal and drain it again, rinsing the tank out good. Wipe the inside of the tank good with a towel.

Re-fill it and get the peroxide, 3%, and add two tablespoons per gallon of water.

Figure out WHY it got root rot and prevent it.
Was the water too Hot ???
Water Pump still in tank and full of trash?

Too much dead crap got in the tank like dead leaves?

I am a new guy starting my first grow with SH bubble ponnics. Everything was going really well until recently. I can not seem to keep my PH down to exceptable levels. The PH keeps creeping up close to 7 and no matter what I do I can not get it down. I have been adjusting the ph twice a day and now my lower leaves are yellowing and drying out and crumbling. What should I do?

All you are experiencing is normal and natural.


After the nutes are added to the tank and the pH is balanced, the plants start eating, consuming the food. Logically, the larger the tank, the more water there is, and the more nutes you need. Logically, the larger the plants, the more they will eat from the tank. Logically, the more plants that are in the tank, the more they will eat. And Logically, the more they eat, the more nutes that you need in the tank. The amount of nutes provided is in relationship to the amount of water, NOT the amount of plants. It is the Ratio or Proprotion in the water that is important. The amount of nutes added to the tank are measured by we commonly call a PPM Meter, PPM meaning parts per million.

The Instructions on the nutrients contain the proper amount of nutes to add to the water, usually determined by "per gallon", and not by "per plant" or "size of plants". In the beginning, we start with 1/4 dose of nutrients, because a full dose is meant for full grown plants. If we use a ppm meter, we seek a ppm of 150 to 250 ppms on average for small young sprouts, it varies from nutrient to nutrient. As the plants grow, we then slowly and gradually increase the nutrients fed to them, and consequently we increase the ppm. By the time the plants are over a foot tall, we will be in the neighborhood of a ppm of 600, then 800 on up to 1200 ppm. Some growers risk even higher ppms, watching the leaves tips for yellowing, to know when to back off with feedings. And as we add more food, the plants grow and eat more, indicated by them also drinking more water. As a rule of thumb, we figure if they drank half of the water, they then must of ate half the food. That is close to being right, but not precisely. If the grow room was exceptionly HOT, they can drink more water without eating more food. And consequently, some days, they eat more, some days they eat less, regardless of the amount of the water missing.

As they eat, they do not eat all of the delivered nutes at the same rate, or same proportion, and that changes the pH and the ppm. It also changes what they call the RNC, or RELATIONSHIP OF NUTRIENT CONCENTRATION. That CHANGE is not easy to calculate or measure, like the ppm or pH is easy to measure.
When the nutrients are first introduced or added, the RNC is perfect, or properly proportioned. In other words, there are specific amounts or precise amounts of each needed nutrient. The exact amount of needed Nitrogen, Phosphorous, and Potash, also commonly called Potassium are present and available for food for the plants.

BUT, as the plants eat, they do not eat all of the nutrients in a perfect proportion or at a perfect rate or equal rate. Some days, they want what grows longer roots, some days, they want what makes more leaves. The plants actually nibble at some nutrients in the mix each day, and gobble down some others. Some of the nutrients are not hardly eaten at all, some are absorbed very quickly. This creates an IMBALANCE of the mix. If you add more water and nutes daily to replace the eaten nutes, (CALLED TOPPING OFF) the IMBALANCE INCREASES. If you only add plain water daily, again, Top It Off, you still get the imbalance. AND the nutes not eaten, or the nutes that are increased daily cause a build up of nutes, and that creates a BAD imbalance of the RNC.
When this happens, the water becomes TOXIC and unusable even tho the ppm meter says there is a proper amount of nutrients. The plants say I AM NOT HAPPY WITH THE BUFFET and like a spoiled child unhappy at the dinner table, they suddenly refuse to eat anything. This is called NUTRITIONAL LOCKOUT. This happens even tho the ppm meter says there are plenty of parts per million in the water. The ppm meter does not indicate if the nutrients are balanced or at a toxic level. It just indicates there is plenty of food on the table.

THIS IS WHY WE MUST WEEKLY DUMP IT ALL AND START ALL OVER.
THIS IS WHY WE MUST DRAIN AND REPLINISH WEEKLY, regardless of whether we TOP OFF with plain water, or TOP OFF with water and a fractional dose of nutes.
Changing the water weekly maintains the proper RNC.

I am answering you twice, see next post.

All bottom leaves dry, get crispy and die off, and the larger the plant, the more it happens.
And daily pH changes are very normal and natual.

Daily Maintenance of the reservoir is mostly keeping the pH at the proper level, and keeping the same level of water in the tank as it is used or evaporates. It is also keeping the nutrient mix or nutrient solution at a proper level, a level that is NOT toxic or too strong.
In the day to day course of maintaining the tank two problems occur. Remember how we discussed ppm, parts per million? Then we discussed RNC, RELATIONSHIP OF NUTRIENT CONCENTRATION. Well, we also need to discuss TDS, Total Disolved Salts. As the water evaporates or is consumed, the concentration of TDS becomes stronger, to the point of being Toxic. The TDS increase as the amount of water decreases. This creates the need to replinish the water, to replace the water. As we replace that missing water, we create an IMBALANCE. Hydroponic grown plants eat what they need, as they need it and they leave some nutes to build up and accumalate into a posionious or toxic level.
This creates the need to daily TOP IT OFF. I have already discussed starting Feedings and Draining and Replinishing in this thread twice. It is simple enough, daily replace what you estimate is gone, consumed, eaten, and absorbed.

But weekly, you need to clear the buffet table and start all over with fresh foods. This gives the plant not only a well balanced buffet table to eat from, but also supplies it with FRESH Food that has not been altered by the plants being picky and choosey.


And, there is the Growth Spurt you will get during the Drain, as the roots get a 5 to 15 mintues air bath. It also gives you the opportunity to look for crimped air hoses, scrub the air stones clean and look for debris and trash in the tank that messes with the pH balance.

Also, as the water ages, undesirable harmful microbes appear and grow in the water. You also take the chance of insect larvae and algae appearing, and weekly draining the tank helps prevent those problems too.

I took off a bunch of roots that were looking like this



Didn't put quite that much peroxide after the drain but there's still a little in there. Water was definitely too hot for a while, up near 80-90 for a few days, but there weren't signs of snot until I started putting ice in the tank to bring the temps down. I know the ice was way out of ph range, I figured it would just bring up the ph slowly enough. I keep getting floating bits of peat in my tank, just flushed the net pots to get any debris out but it seems to have made the debris problem worse. I think I'll pick up a little fish store net to grab the gunk when I see it.

you have a lot of obstacles to over come.

This is why I didn't invest in seeds, I'm already wasting a ton of nutrients on all these supposed-to-be-beneficial res changes

SUPPOSED TO BE?

Without them, your plants would of been dead a long time ago.

OH I know, but the changes don't seem to last me very long at all, plus if you screw one up bad enough it'll do more harm than good

drabstab,

Read post # 1744 and # 1745

Of course I know proper res change is always good, but I've only been growing this way for less than a month and I'm making tons of mistakes. When I see my res temp is high, I know that's bad. So I try to fix it. When my roots are slimy, I try to fix it. My point is, I have already run into these problems. I know what optimum growth conditions are, but I already let them get out of hand, and I'm trying to fix what I've done. Meanwhile I'm considering scrapping this grow and re-upping on EVERYTHING that I'll need to keep my conditions optimum. Running into a problem unprepared for it makes it much harder to remedy.

EDIT: Just realized this may come off a little rude or ungrateful, please don't take it that way, I really appreciate everyone's advice, esp. yours

We've all had problems and times when we thought it best to give up and start over but you have to remember you are in learn mode. Don't expect much bud this grow but you will learn how to grow properly start to finish, confront and fix the problems that occur and get your grow room prepared for the next grow start to finish.

Does anyone know if you can take clones from an autoflower plant? I have 5 Bubblelicious plants getting close to where i think i could take a couple off. thanks for any help.

Sorry about the last post I found it after I asked.

Is Sub Culture M a good idea? I'm using the GH line

drab, i feel your pain. Sometimes it seems like no matter what I do my res temps are up around 80* I'm gonna end up getting a chiller and modifying all my systems to accommodate it.

drabstab said:

Click to expand...

I use the GH line as well. Let me tell you how I mix a batch...

1. Fill the rez with water
2. Add your dose of H202. I use about 1 tsp/gallon of 35% H202. If you're using pharmacy grade (3%) use at a minimum 2TABLEspoons/gallon
3. Add your Micro
4. Add your Gro and Bloom
5. Mix and check ppm
6. Test your pH
7. Adjust your pH
8. Test your pH again
