Mag,Iron deficiency help

[OldSoul777]

Hello everyone! I made a bit of a mistake. My GH cal mag say 1ml per liter( 1 teaspoon per gallon) well I read wrong and only gave 1 ml per gallon for entire grow. I am 8 weeks into veg from seed and ready to switch over. I am showing new growth as yellow and some older leafs turning yellow. I think its a combination of a couple things. (not sure) So before I figured out that I messed up on the dosing of cal mag I diluted the base nute mix to 750 ppm from 1140 then added the cal mag. Should I leave it at this PPM or bump it back up to 1200 with the calmag? I was afraid I had a lockout at first because I had my nutes up to 1500ppm before this happened and I noticed some tip burn and quickly did a res change as it was due. That was three days ago. She is taking up nutes because last night I had ppm set at 1250 and this morning it was 1140. Any advice? I hope I explained well enough! Ill get some pics. I think I caught it early enough! plant still looks ok. oh i did ass 125 ml calmag to 25 gallons just 10 min ago

You're making this so complicated. Don't add Calimagic. I don't see any reason to ever exceed 1000ppm.

Tap water or Reverse Osmosis? What are you growing in hydro, soil, coco?

 

[Jeeyah]

Oh. You did a res change. You're in hydro. If you're in tap water, I wouldn't worry about Calimagic. Calimagic's just nice to green em up here and there, especially the first couple weeks of flowering. If you are going to use Calimagic, add it first before your micros. You're ppms should not exceed 200-250ppm or so after adding Calimagic.

RO water. I added the cal mag last. WTF I dont have anymore ro water made. I didnt know I was supposed to ppm the calmag. I just added the recommended amount. will this be ok?

do i calculate the final ppm with the calmag or say 200 ppm of cal mag and 800pmm of nutes if say i was previously at 1000?
after

One more thing. I started the flower cycle yesterday. Shoud I revert untill the problem is fixed? i read that the plant will use even more cal mag during flower

What kind of hydro? I like urdwc. Don't just read the bottle. I can only eat 3/4 pound of filet mignon. I can't eat 5 lbs of it. With growing nuggets, less is more. Sometimes if you add too much of something it locks out other things.

First, add Calimagic at a very low dose. Let it mix for a little while. Get the ppms to 200 on a 500 scale meter. (I think most are 500 scale).

Once your ppms say 200 you will have a perfect balance of mag, iron and calcium all ready to be used by the plants. Awwwwww yeah.

Then add your micro. Mix it up. Wait. Add the bloom. Mix, and wait. I usually veg around 250-350ppm. In flower I keep it around 450-600ppm. I run some sensitive ladies though. With some indica dominant you could go up to probably 1000ppm.

 

[Jeeyah]

If your ppms are dropping I would just leave it. What strains? What type of GH nutes? What type of hydro?

When do you plan on changing the res?

 

[Jeeyah]

This will be super easy once you get a nice regimen down. Just note the measurements once you get the right cal/mag dosage etc.

Everything was going so well. I use a RDWC. I am growing idica dominant strains. I am waiting for water to make now. I wont have 30 gal for another 5 hrs or so. I dont think I over did it but not sure so I suppose I will do it again. So would you go back to veg until the issue is fixed? I only did a 12 12 cycle for a day now

If everything is going well, smoke a joint. You said you added LESS than the recommended amount right? No rush to change the res.

If they are strong, perky, and happy don't touch the timers. Flower those bitches. I pump my system out about halfway once every 2-3 weeks or so. But, that's me. Lol

LMAO. Thats just what I did and slept on it. BTW thanks for the advice! I'm sure you know what its like when you see your girls not doing what they are supposed to. Ok wont touch the timer and let them rock out and flower. You the man!!!

 

[OldSoul777]

looks like things are improving. Def got some green back. I used 5ml per gal of calmag as a foliar spray as well.

Can I get away with using Coco Grow and Coco Bloom base nutrients in a non Coco purely hydrotone RDWC system?
