Mephisto Genetics Help with yellow leaves?

[slowandeasy]

Cal mag every feeding. 2ml per gal. Food is Mega Crop at 4 grams per gal.

Is it MC Version 1 or 2? What kind of Calmag? pH possibly could be off, use another meter or drops to confirm. Make sure yet ur meter is correct. What kind of Calmag? What are your lights? What kind of Coco? I don't use MC 2, MC 1 was better. My friend used version 2.0 and had very similar stuff going on like you. He couldn't keep the plants nice and green. He used a pump and Halo rings. His pH was wacky and he stopped using it because of the drifts were too wild. Personally I would like to give you my advice. Use better nutes, MC V2 is not a good choice in a Rez. Jake had pale looking plants, just like yours on MC 2. I gave him some AN nutes I had laying around. His plants look perfect now. His pH was the problem. Hope you get it straightened out. Peace, slow

I'm not at all sure since i got 3 seperate samples of MC, but do believe it is version 1. The cal mag is GH. I've used it for a few grows from last to this year so i know it's fine. I do still have GH Micro and Bloom which i always do well with and love so i guess that's an option. My PH was 6.0 when i put the cal mag and than MC in it, but i can check the rez to make sure. I only fill with 1 to 1 1/2 gal so as to keep it fresh every 3 days max. Everything was fine 10 or so days ago all green so not sure why they look sad at the moment.

Ok. I have Autopots as well 3.9 and 2.2 size. I just wanted to try to get even smaller and see how they did. Appriciate the help, and I'll get the plants a bit more food.

Stick to the 2 liters!!! You got that shit on lock!!!

I would check the PH also. My entire tent went yellow this week. I use AutoPots and I never check the PH once I fill the reservoir. PH was 6.8 and the ladies had no other option than to follow that damn "yellow" brick road. You are going to love the Chemdoggings.

One day I will get to my Chemdoggings...

i would up that calmag slightly also my good friend @Nosias some good things to check the ph i check mine religiously also i have a small pump to keep my feed from settling at the bottom but never use an airstone as it can cause massive ph problems

Ohhhh!!! I didn't know that about the airstone!!!

They may be out growing the container... 5 of mine outgrew their pots and stayed smaller than they should have... Didn't turn yellow though,only the plants in my autopots... This is food for thought...

MC 2 turned my plants yellow too!!!

MC2 is completely different, in a worse way. I don't likw anything about it. However Version 1 was the bomb. MC2 is Sulfur based and has different ratios. Plus chunks of Calmag that dont mix right. Once my Version #1 was out, I stopped using it. My buddy had Yellowing going on. Wild pH swings in the rez. Not worth using it, too inconsistent
