Brown Spots

[Jabapc]

I've grown for years and never had a prob with this till I started growing White Widow...I thought it might be a Mg deficiency...first I tried adding Epsoms salts ...didn't help...I grow hydro...I've used Jacks for years...ph 5.8 to 6.2...tried switching to Maxi Bloom...didn't help..then tried Botanicare Cal Mag...still no help...any ideas...Jaba

How strong a mix are you usin? Where on the plant is this occurring? What stage are you in?

 

[Jabapc]

I use about 3/4 strength with all nutes..it happens more farther up the plant but it happens on the whole plant...this leaf is off the new clone that's about 1 1/2 months old going into flower in about 3 weeks...but it happens just the same on my flowering plant

Ca-, if it happens near the top.

I'd say -Ca also. If ya addin Ca, wat's yer application process? Try dilute in a warm water foliar spray. Makes tha leafs all milky like lookin but it's more effective for absorbtion purposes. Good luck and be ready ta fight Ca def fer awhile. Hard ta catch up on.

Calcium pure and simple. Get a Cal product and use it. If u only have or can get Cal mag that's fine but it's not a mag problem it's total calcium. So demeter s destiny from nftg, calplex from organic-fertilizer, calcarb foliar from x treme nutrients. All things that will stop Cal Def.
