Whats this deficiency?

[Sinsemillian]

Well after a day upstairs and no watering the clones seem to be comming along great. The new growth looks good. They are now under 1200 Watts of HPS which is 4 feet above them. Still trying to find my air cooled fittings for the super sun reflectors. I think they may be at my buds place which is an hour away. The rez temps are now 73F and humidity was mad in the room so I took the cover off the attic and now RH is down from 70% to 55%. The entrance to the attic is in the closet of the growroom so soon I will try and tie all my system together once I get the A/C fittings for my reflectors and all. Well all in all I am happy the clones are doing better. Hopefully soon I will have the whole room under control and more efficient.

Sinse.

I looked at the pix of your hydro babies in the homedepot buckets... they aren't looking to bad at all.... I think as long as long as you don't get carried away with OVER fertilizing these girls your fine.... also, I liked to run my rez temp at 68 but if its colder in the room etc, 72-75 should be fine for now, ideally though not much higher. Thats one of the good things Hydro Guard does, is protect the water against higher temps, I used it when doing hydro.. botanicare right??. Cold temps can interfere with some of the nute uptakes.... I am dealing with temps in the mid 40's in un-insulated plastic wrapped rooms and have had problems with IRON plants "little seedlings" were COMPLETELY yellow every leaf on em... and I threw a space heater, lowered my PH and they grew out... so I know your will be fine..

I don't use the AN anymore so I have to re-familiarize myself with the values I used, but yours soumded fine for now.... eventually (next 5-7days you want to move your PPM values up gradually AS PLANTS IMPROVE.. I eventually found that my plants did better with lower values of NPK than what the AN calc recommended...
Prby why your plants did fine in dirt with the PH thing, is cause dirt is a lot more of a "buffering" substrate, hence more forgiving..
I will get back to u tonight after reviewing my "notes" and give you a couple of examples of how to approach the feeding thing. and adding in some of the additives that you have... Fulvic is good stuff.. I just like to make things REALLY SIMPLE when I run into problems, makes it easier to fix em fast, then get back to the whole prog..

I run my RO into a 30gal garbage can... if she overflows it goes onto the ground... whenr running hydro I had a bathroom nearby with shower ... i tood head off show through garbage can in hooked up RO let it run in to garbage... when overflowed, just down the drain!!

Peace

Yeah I agree bergerbuddy. I think maybe floors in basement were to cold. Even though i had the buckets up on thin strips of 1" styrofoam. They seem to be rooting fast now and new growth greener since moving them upstairs. The room temp is 80F lights on and 70F lights off. I started a grow dairies bro if ya wanna check it out http://www.icmag.com/ic/showthread.php?t=51178 The hydroguard never came in yet so hopefully monday it'll be in. Over the weekend I am going to put 2-3 frozen 2litre bottles in the rez to maintain 68F. i flooded the system once just to get the hydroton wet. I flooded until I was 1" below the rockwool cubes. Now the PPM in the rez is 340 and the PH is 6.1. Well I look forward to hearing your examples after your done reviewing. Thanks again for the help bro.

Hey Guys,

Have recently posted this to a few out there - would be interested in your thoughts. Have never done hydro approach and understand PH issues may be very different. I've recently gotten over a maddening problem that ended up being Mag def. I have been told Mag is locked up at PH's lower than 6.3 or 6.4... Is that just in soil? Also, I've been told that RO water generally must be supplemented with Cal-Mag or you will definitely show deficiencies.

Thanks Guys,


Wildheart


Seems clear to me that you are experiencing a magnesium deficiency, something that is starting to become a problem for many, hence AmercanAgritechs Botanicare product called Cal-Mag.

The key factors in determining your deficiency are that the problem started lower on the plant and is working it's way up, the first two or three weeks were probably just fine and normal but now problems emerging, lower level fan leaves beginning to wash out, then soon after begin to burn along their tips and then Viola! the leaves will beging to CURL UP!

Magnesium deficiency. Easily cured!

Chronic Newfies advice is spot on... Hopefully you have a very good Hanna PH Tester - mine costs about $125 and I have two of them, and they are constantly calibrated with both solutions, 7 and 4, as well as stored in 'Storage Solution'. Again, if what you are doing is worth it to you, then I strongly encourage you to learn your water to an EXTREME degree!

Acording to consultations with AA and General Hydroponics, magnesium begins to be locked away from the plant at PH levels of 6.3 or 6.4 and below, leading to these types of problems within two to three weks. Cal-Mag is the way to go. add as necessary... you may find that you have to add cal-mag with every watering as I have found. Having tested my water I found that I have a source and water system that is mag. deficient. In that scenario I have to add Cal-Mag with every watering. People that use RO water are strongly encouraged to do the same. Rapid rescusitation can be acheived by a foliar of Cal-Mag (1/2 strength) as well as the watering.

Magnesium deficiency is considered fourth most common plant deficiency after Nitro, Phos and Potassium. With the foods and soils most of us are using the first three just aren't showing up that often anymore I would imagine, leading quietly to Magnesium deficiency now becoming most common??? I hypothesize...

Hello wildheart. I have a nutradip tri-meter which is for my rez. It constantly measures the PH, PPM and Temp of the nutrient solution. Hydro is a different bird as is not as forgiving. Cal-mag is a definate must when using RO water. Our towns water has a PPM of 100 and the main minerals in most treated water is calcium and magnesium. RO water strips these minerals out thus leaving you with a 0 PPM solution. Here is a graph I have went by for years in soil for nutrient uptake availability. Save a copy of it as it is a handle tool for any new grower. I have these figures memorized for soil but take a look at the graph for hydro uptake as its way different. For instance check out calcium and magnesium uptake in soil and then look at them in hydro. lol They are totally different. Something I never noticed b4. Nutrient uptake in hydro is a slimer range as compared to soil. I have to get used to this now and put all the soil knowledge on the back burner. So basically hydroponic wise I know about as much as you. I am learning each day but I have found that you can read, read, read till your eyes bleed but you actually needs hands on to understand it. I read tons about hydro b4 I tried it out and yet I still have problems because when your actually doing it all you have read gets referenced. But just like anything else after you do it yourself hands on you learn from it and get better. I remember my first soil grow. Was very sad indeed. Although now I can tell any problems that arise and can figure whats wrong with my soil and what I need to do to solve the problem. Well I am off. back in a few hours with some pics. Thanks for your input as its much appreciated.

Regards,
Sinse.

Sorry for not posting the pics last night. Everyone in town is being hit hard by the flu and I think I just picked it up. Man do I ever feel like crap. The plants seem to have taken a turn for the better. Today was the first day I started to flood 4 times for 15 mins each. Although on the last flood they been looking droppy so I think I over watered. However all new growth is green. I think I was starving them for 2 days when only flooding 1 time per day. I am wondering when I should be topping the rez off? The p.h rose up to 6.3 so I adjusted it to 5.7. and Rez temps are 74F so I hope tha fuck the hydroguard gets here tomorrow!!! lol I am bringing rez temp down 3-4F throughout the day by putting frozen 2 litre bottles of water in. I moved the lights down 8" and they are now 26" above the tops of the plants. I noticed the PPM never changed at all today as well. If anyone has any advice please let me know. I take it its hard to tell if they are eating when they are this small? Forgive me for the questions but its hard for me to tell. Do I top up with straight ph'd water? I dunno. lmfao. Well thats it for now I guess. Bergerbuddy if your out there bro I need your help cause this grow got me confused. Would it be ok for me to pm you?

Regards,
Sinse.

YEah man they are def. looking nice.


what are you feeding them and how much?? looks like things are going well how big do you veg b4 budding??

Peace

Well right now I have them on 950 PPM. They are beefing up bigtime now. I did some LST on them a few days ago. Here are a few photos of what they look like now. I just purchased an ecogrow hygrometer and it shows my humidity at 20% up in the growroom. I had previously been using a thermometer with a coil for reading humidity. Funny thing is I think the coil works and the ecogrow dont cause when the coil says its 70% the ecogrow says its only 50% but yet it feels like I am in the shower the humidity so high. After this grow I am going to be switching to Botanicare nutes. Advanced nutrients has been nothing but a pain in the arse with these buckets. You have to mix the micro up first before anything else so after mixing everything up and your PPM is to low I guess your fooked. This has been a pain in the arse. Reading grow journals from bucket growers using Botanicare nutes seems to easy and is the route I will be going next. I been misting the girls a couple times a day and have raised the 600W lights up to 29"
