Other Tips:

  • Maintain a nutrient solution pH range between 5.8-6.2
  • The optimal temperature range of the nutrient solution is 20°C - 24°C (68°F - 75°F)
  • If using a drain to waste system, allow 10-20% runoff to decrease potential for salt buildup. If no runoff is planned, reduce the PPM/EC to prevent potential salt buildup.
  • If using a recirculating system, maintain water level in the reservoir by adding fresh water and nutrients as needed. Change solution every week.
  • If growing in coconut coir-based media or if using reverse osmosis water, add 1-1.5ml of Cronk Nutrient's CalMag 2-0-0 to the nutrient solution recipe.

Great so far

I am only in week 4 of veg yet but things are going great. Little nutrient burn first week which was easily dealt with in the following week. One interest thing, I have not had to adjust ph at all so far

Chris Conwell
Great Deal!

I have purchased the big bud kit twice. I love their nutrient line! No issues when following the feed chart.

Honest review

First and foremost cronk nutrients has stepped up my garden from upper mids to top shelf! A+ for that! The negatives, slow shipping, bottles come busted sometimes(bubble wrap might help) so order way in advance incase these things happens. Also there are way too many parts which makes it a bitch everytime you water. Cause of this I’m gonna experiment with Athena to see if i get the same results at least. If so I’ll switch cause mixing 5 or 6 different bottles during flower gets annoying. If i Can cut any time I’ll go that way!!!


Thanks for the review. We want to let you know you don't need to mix all of these nutrients to get great results! You can get amazing results with just using our 3-Part Kit from seed to harvest. The additives are just that, additives, they aren't required :)

We appreciate your support and hope to see you coming back :)

Ray Grehofsky

Fantastic product. Use as prescribed and you will love the results. Also they rejected me as a tester because I was a current user of their products. Thats integrity. Thats why I do business with them. Our friends from the North have it dialed in. Im not goin anywhere.


Love it as always
