Evidently, the FoxFarm nute schedule is too strong. This type of "burn" happens in every one of my Jack Flash crops. Unusually, it occurs much later in the Flowering cycle as opposed to this time when it started in the 2nd week. The "schedule" was not created for cannabis plants & being that not all plants are created equal, it's entirely possible it's overkill - no pun intended.

I'm going to straight water the next 2 times, then go 1/2 strength on FoxFarm. If anyone has a better way of handling this, I'm all ears.
Happy Retiree Reviewed by Happy Retiree on . Is this Mag & Cal or ? deficiency? Hello... We're growing indoors in soil. Take a look at these photos. Does it look like a magnesium &/or calcium deficiency? The plants just started their 6th week in flower. We fertilize every other watering & pH is always around the mid 6's. PPM in our water is around 60. Day temp in the room is around 75. Thanks for your help. 289924289925289926289927289928 Rating: 5
