So DWC setup. 5.9 ph. An ph perfect nutes full strength. Did a rez change yesterday. I do one every 5 days anyway. added 40ml of calmag last yesterday as well. Plant is at day 39 and is fucking HUGE see link to the thread. I am thinking cal but I am not 100 sure. Deficiency is located on upper 1/3rd and 90% of it is on the top forming cola.
If the upper bud leaves are turning a orange rust color it's usually from cal/mag def and if your running LED's it happens more often.
40ml Cal mag + how much nutrient solution?
30ml of a.30ml of b pH perfect. 4.5 gallons of water
I hate calmag because of the extra N. Might change out by ket again and do 20 ml of part a to cut out n factor
General Hydro has only 1% nitrogen witch is not really enough to worry about,or you can use molassis that doesn't have nitrogen.
No Idea if I can use Molassis in dwc Nam??? Does it have Cal? I am using boticare calmag now and its 2-0-0

:smoking: TJ-- ....I need a better pic sowing the symptoms please,.. from what i can see though, my first thought is Ca defc. too,... given the size of that beast- 
- and the timing, Ca is in big demand right now,... 1-0-0, 2-0-0 is not an issue as long as you're PK# are fat,.. beside, the amount actually going in per dose is low, well below what a dedicated fertilizer has,... I'm not a DWC guy, but molasses and it's sugars can potentially make undesirable microbes go nuts too-? As a source of Ca, Mg and K, it's pretty mild, not the best for treating defc.'s, especially one that is poorly immobile like Ca is,...
