Hello, I am new to this forum. I joined because I am a new grower and I have run into a few problems that I could use some help with. I am growing ak-47 auto grow seeds, I have 6 plants. Now they have come down with an illness and I can't identify what it is so I need some help. 3 plants are 1 month old and the other 3 are about 2 weeks old. The older plants are getting spots and turning yellow. Here are some pics to show you. I have a 4x4x6.5 tent and I am using a 400 watt mh light. I have carbon filter, all the fans I need and I am watering with distilled water. For nutrients I have fox farm big grow, tiger bloom, and liquid plant food. I also have sm-90. Please help me!!

That's a Calcium Deficiency my friend just get some cal-mag when using RO or destilled water you will need to replace the cal-mag that is removed from the filtering its going to effect your over all yield on the plants that have it but you know now so just get yourself some cal-mag and it will help it from taking over also check your PH and make sure it's above 6.0 i had this on my last grow on only one and it was stunted and sucked but this time i am running the same plant with high calcium and shes a happy girl all the best and good luck

The leafs that are already damage will not recover but it will stop it from happening to the rest it will take a couple of days but you should be able to notice a change

when it comes to using soil most will tell you when using RO water and destilled water use it all veg and the first 3 weeks of flower as the soil will hold on to the cal-mag till the end but it never hurts to add it i think its better to have then not and run in to trouble if your using COCO perlite or any hydro and using RO/destilled always use it :) all the best i am sure she will recover will never be 100% what she could of been but she will still give you some good smoke

Well thank you! But one last thing I read and it said to not give cal-mag during flowering because it will be too much nitro for the flowering stage? Is it safe to use because my plants have bids with the white hairs all over them

figured id toss this out there ...... since i didnt see you mention PH
Distilled Water Absorbs Carbon Dioxide
  • The pH of pure, distilled water in a vacuum is 7; it is neither acidic nor alkaline. Immediately after distillation, however, water begins absorbing carbon dioxide from the atmosphere, and it forms carbonic acid -- a weak acid. This absorption continues until the carbon dioxide concentration in the water is the same as it is in the atmosphere. At this point, the pH of the distilled water is around 5.8.

most cal/mag is very low N ..... and honestly thats when they need it most since the soil / lime is used up

and the lime is what buffers your PH in the soil ..... see what im getting at ? its been a while since i used fox farms maybe someone with more experience with it then me will chime in .... but i think it drops your PH when mixed :confused: possibly locking calcium out ?

Well thank you all for the help! Looks like I will be getting the cal-mag tomorrow! Should I go by the directions in the bottle or should I do what ppl have told me to do with the fox farm and use half of what the bottle says? So far only 1 plant is badly affected
