Was wondering if this is a calcium deficiency? See some similar pictures with people saying that it is a result of the pH dropping below 5? Could this have anything to do with me LEDs potentially being hung too low? Any help would be much appreciated, thanks!

I had the same problem. In my case I grow using LightMix from BioBizz. I use underground water, which apparently is low in calcium. So I could correct my problem using CalMag also form BioBizz.

It can be a deficiency or it can be a lockout, meaning calcium is there in your substrate but for some reason your plant isn't uptaking it.

Give us more information please:

  • soil or coco?
  • tap water? underground water? bottle water? RO water?
  • Do you check your solution pH before fertigating? If so, how high/low is it?
  • Temperature? Soil temperature? RH? Water temperature?

Hi galandil! Hope you were able to get your calcium deficiency under control. Currently the medium I am using is soil (biobizz allmix). Majority of the water I have been using have been rainwater that has been collected except one water on day 29 using dechorinated tap water. Have not been able to pH prior to feeds but rain water should be in the 6-6.5 range, no idea in regards to tap water but I think i have hard water in my area if that's helpful. Temps around 20-23c, rh around 50-57% and water will be room temp. Thanks for the help, much appreciated!

Yes, I could correct my problem using CalMag from BioBizz. If you are using BioBizz products you should be able to get a hold of a bottle of CalMag.

I doubt rain water has enough calcium for your grow. It's just like underground water. You could try tap water, which usually has more calcium (thats why tap water is hard and has lime or chalk, Kalk in german) but tap water comes with another problem, chlorine. Usually is put into water to kill bacteria, both bad and beneficial. The problem is there are 2 types of chlorine used to put into tap water. I don't remember the names right now, but one evaporates in air and the other doesn't. And if your tap water has the one that doesn't, then it can kill the beneficial bacteria you have in your soil. Usually you can check that in your water supplier website.

If you can make sure you have the one that evaporates in air, then I would let tap water sit on a warm place for at least 24h so that cholrine evaporates and use that to feed your plants whilst you get a hold of CalMag, perferably organic (BioBizz or similar) and not synthetic.

Looking at your pics I would use 0,8ml/L CalMag on the first time with rain water, than 2-3 times 0,5ml/L and after that 0,3ml/L for every time you use rain water. I've been using CalMag on all my fertigations after I had the same issue. And it worked.

Check out my journal, where I show pics of my calcium deficiency.

I hope this helps, let us know how it went. If you have more questions, we are here.
