Always the same leaf trouble...

[code9]

Multi-flow bucket system (2 gallon) seems to always have the same trouble with leafs turning yellow, purple and some spots. Also the leaves curl. Eventually they turn brown and dry and fall off or I take them off. See the pictures below.

Sealed space with A/C
Temps always between 69F-82F
Air cooled 1000w HPS about 2 feet from plants
CO2 between 1100-1500ppm when lights on
Humidity 30-50
Res temps 69-75
PH 5.8-6.2
GH Flora Nova Bloom 1 part (about 6-8ml per gallon)
Vita-grow Water Conditioner
Cal-Mag
sometimes SM-90 and or Hydroguard
Buckets watered when light comes on for 1 click and then about 8 hours later for 1 click and none at night.
Sensizyme or Hygrozyme
CarboLoad
BigBud weeks 2-4 or 5 and Overdrive weeks 5-6 or 6-7
Always have to add a bit of PH down now and then

Maybe looks like nitrogen deficiency but not sure since it looks like other deficiencies too. Any help is welcome. I will be posting the grow in detail in the next month or sooner.

What is your water schedule? 1 click? Is that for 15 minutes? Sorry I didn't understand it. Welcome to ICMAG. We'll see if we can get it right for ya.

actually it looks like you may be overdoing it. looks like a lockout from a ph caused by too high of a ppm, but im not used to hydro, so i might be totally off my rocker!

resinryder - the control bucket i use allows watering at 15 minute per click. As the control bucket fills the other buckets fill. And thanks for the welcome. I have been around here for a while but under another name. Did not post too much, but learned!

jonnybgood29 - It could very well be lockout. The PPM is around 1100-1200 with a trimeter.

your not too high then so i woulf first do a good flush of your sys and mix up just the nova only the nove and calmag at half of what you are using 500-600ppm for one week to let your plants recover... your running too hot right now for the condition of your plants... also dont add your calmag for a few hors after mixing in your nova. if added too soon, it can actually cause lockout from the concentrated mg hitting the partially mixed nova locking the nutes out before it ever becomes available! when your plants show improvement is when you start upping your nutes.


cut back on your different chemicals as well. you might be getting a nute mimatch as well. try putting each of them back in one at a time giving several days in between to see which one if any is giving you the troubles!


any of you hydro folks think that this is too little watering or is it just me?

 

[code9]

I usually do not wait more than 10 minutes to add the calmag. I will try as you say and wait longer. thanks. I will also cut back nutes to see if that helps.

When you say too hot do you mean room temp? With the CO2 a bit higher temp seems to be alright.

Cal-mag has been reported to be 300% the strength listed on the bottle. Use 1/3 the amount, you should probably flush in order to overcome the lockout that has occured. Dont know if using a flush product would be needed other than just plain r/o water for a bit.

You are also using sm-90 and hydrogaurd together which are counter productive since sm-90 is a sterilizer and hydrogaurd is a benecitial bacteria colonizer.

With the amount of additives you are using its going to be hard to pinpoint what is actually doing the damage. Lighten up on the extras, stick to the basics and your problems should clear up.


Anyone else have any thoughts?

no, i mean your nute strength is too strong, ie hot, will burn the roots causing further problems

UV - I did but you seem to have them covered. Sound advice IMHO. code9 It does look like you've managed to get some chunky nugz in spite of your trouble. You said this was a recurring problem? Is this with different strains? When does the discoloration start to show? Those are some freaky lookin leaves.

You are not feeding enough IMO. I flood my table once every 4 hours. 1 hour before lights come on, 4 hours later, etc till lights our then 1 hour before lights out to carry them through till morning. Use either SM-90 or Hydroguard seperatly as suggested by UV Dreams. Different plants have different Mg needs. With using RO water I add 3 ml/gallon water. Some strains will need 5 ml/gallon. The plants will let you know if the need more. Run a mild nute solution for about a week using just the Flora Nova and CalMag. This will provide some food needs but will aslo pull out some of the "salts" out of the plant. Then go back with your adjusted formula. Keep the ph between 5.5-6.0 from here on out. You might want to do a flush with Clearx for a hour or so until the ec/ppm of the water stables out. Then use the mild solution. Hope this helps. At this point you're gonna have to baby them to the final chop. Good luck with them.

I will give less calmag and nutrient. I will stop using sm-90 with hydroguard. I do not use RO water. Part of why I started with the CalMag is because of this problem with the leaves.

WeedWrapperMan - I have done this same strain many times before. It is a bubbakush and very strong. The nugs are indeed chunky and even with the leaf trouble will produce great sticky dense smoke
The problen starts around week 3-4. I don't always have the trouble, just most the time.

resinryder- I am also going to lower the PH more than in the past. Maybe shoot for 5.7. As for watering it is difficult with the buckets. If I water more often the 4" cubes stay too wet and cause other problems. I have used as many as 4 waterings in the past with the same problems. Also I will flush with Flora Kleen or Clearx but the buckets don't make it easy to flush since the water only hits the bottom of the cube and only for a short time. Maybe I will hand water the flush from the top of the bucket.
