Help with flowering plants in soil (yellowish dots)
HI all, this has just started to hit both plants in the last few days. I have recently noticed that there are some splotches and / or dots on the leaves on my soil plants. They are in organic soil under a T5 HID light in a box. The box is pretty well ventilated except for when its flowering at night. We have a pH pen but have not been using it due to the organic food we use and store bought filtered water. The plants have been fine up until this point. Thanks for the help!

Help with flowering plants in soil (yellowish dots)
I'm going to say Calcium deficiency is a likely culprit... based on the tip burn, you have a lockout and need to flush before doing any more feeding. Then start up on CalMAg and reduce the strength of your bloom fert, which at the strength you are feeding is scorching your leaves.

One more thing, I was thinking MG deficiency based on what this site: Grow Marijuana FAQ, Cannabis cultivation - marijuana growing tips & photos indicates. Also, these plants are in day 34 of flowering

The plants WILL finish.
That isn't Mg. You would be seeing pale stripes if it were.

thats awesome! I always thought the people that dog on "online daters" have a lame argument since the internet is a medium just like any other eg: bar, park whatever. Anyways, I am glad you are happy. We are currently in day 3 of flushing with pure water. Do we mix the calmag in the water for a few days and use just that or mix it with the food also?
Another thing, ChronicChrissy.why.do.you.spell.like.this?
