Every Grow I Get This Problem

[Waira]

Haunts-- dig that bonus plant pic! -that is one chunky chick! .... she looks very much like she should at this stage,.. the one above her is rally tapping deeply into closer leaves for several vital nute's, from the look of the mixed symptoms,... a lot of draw to support those fat buds! When you see it start happening earlier, up your nutrient dosage or better yet frequency, and see if you can ease the draw pressure off some,... like good brother Trap says, the girls should look haggard by harvest-- purdy don't don't getcha stoned, sticky bud do!!

Ca defc., a common issue with autos, along with Mg defc

Hey Waira, hope your well man are these common auto defs you speak of only related to grows under lights ?

Looks good I let mine get a little tip burn then back off the feed and if its the same strain next grow then I would give a lil more cal/mag too.

Vas, all's well enough mate, thanks!,... and yourself? Yup, Ca and Mg defc. are at the top of the list in general, but LEDs seem to magnify this problem even more so,... Many folks just add a little extra Ca-Mg with their feeds and/or watering as a preventative measure, and even then, sometimes it's not enough,... transition from veg' to bloom, on through blooming, is when it tends to show up....

.... Doobie! what's good my friend?

Thanks Waira, I have those minerals in my soil, so long as my soil life is firing & balanced, should be plenty available for the little ladies. All good here mate, springs nearly here, gearing up for a big season of auto experiments in the aussie outdoors. still getting my head around treating auto's different to photos lol. Learned so much in the last few months looking forward to my grows this season...

autoflowers are a strange breed been growin them 4yrs now I feel your pain this is a calcium magnesium issue to fix add some cal/mag it will help a lot but for the future I learned a little trick that helps a lot when the family uses egges I have them put the in a bowl then I clean out the shells and dry really well then mix them in a blender until powder then at around week 3 to 4 when they need water I put into a gallon of water 1/4 teaspoon egg shells 1/4 teaspoon ebsom salt and 1/2 teaspoon unsulfured molasses water them with this take extra shell powder and sprinkle onto ypour soil around the plants then there regular feeding times then just give them the cal/mag when they show you they need it soon you will know your plants like you know a cat or dog just by looking at them you know what they are thinking hope this helped happy grow
