It depends on your tap water. My water comes from a well and has some magnesium and calcium so it's actually better then rainwater since I don't need to add calmag. If you have city water I'd say rainwater is better. The tap water from my local town has a very high pH and chlorine & chloramines.
Thats a bummer man, probably toxicity as afformentioned, and pH issues. We all eventually have plants that just die or look like poop, it is what it is all we do is move onto the next. Good luck with the next one
Yo man, I don't know if that's the color of new growth or a deficiency.
Though in my AK420 diary, I had this same coloring.
Some growers suggested I should be mixing in about 0.4 grams of magnesium sulfate until 100% dissolved (about 1/4 - 1/6 a tsp, taking density of magnesium sulfate to account) and 0.5g of calcium nitrate in tap water, until 100% dissolved. Then I added some pH-down after mixing in the magnesium sulfate and calcium nitrate. I used 20-25 drops of Terra Aquatica pH-Down to my 1.5liter bottle, brought it to under 6pH.
Btw, the upper recipe is for COCO only, and 1.5 liter water. Though for a gallon, about 1.2grams magnesium sulfate and 2 grams of calcium nitrate should be used.
For soil, I'd probably try both the calcium and magnesium first. When the brighter coloring is gone, skip adding the magnesium to your water, as this might just cause an abundance of unnecessary nutrients.
After a few waterings, the color on my AK420 plant went away. And by no means am I advertising my diary or products, I'm just giving some advice, grower to grower.
@@badaboopbapow,I was thinking along the same line. I picked up a Cal Mag supplement and am now working that into the feeding schedule. Thanks for the advice bro.😎
You know I have no experience. But I read that discoloration at the top of the plant can be a deficiency of an "immobile" nutrient like Calcium. Maybe that narrows things down? Trying to help if I can... Good luck, buddy.
@@GrowsInLoft,
I think you're on the right track. I've read that one of the things that can keep plant from absorbing key nutrients like Calcium is a ph imbalance. I've been taking steps this week to get things back inline and so far I think things are getting back to optimal.
