Asa,
Only two of my plants showed cal-mag def in my first grow... The others did not. I can promise you that you need to be adding cal-mag to your ro water. Biotincare makes a product called cal-mag it's a supplement you add 5ml per 1gal of water. When making your ro water you are removing all minerals from the water... The plants need cal-mag... It's a very cheap and simple solution just order that supplement... Also don't stress your self out so much over the details... Let the plants start telling you what they need... Sounds silly but meditate by your plants, talk to them, watch them... Take notice in the subtle changes, they'll let your know when they need a watering, when they are over or under fed etc... I've had a couple plants that would have all their leaves drooped down when lights go on, appearing to look like they needed to be watered, only to notice as time passed the plant started to "wake up" and in a couple hours times all the leaves were up.. With no intervention on my part... Another example is another plant will display same behavior but watering is exactly what that plant needs and wants... Keep it simple, you have the right tools to get the job done, you show a passion and dedication to your grow, just project in your mind your harvest curing in those good old mason jars! If you look through some my older post you'll see my gom grow log there... Planted 4strains for first grow... Gom so far has been my favorite, fluffy compact buds! Great taste, just so so smell but than again I'm around it all of the time I have a poor smelling sense to bud...very smooth smoke going down, a lung expander, smooth exhale.. Good hour high (though am quite chronic) very nice bag appeal fluffy and compact,',,
