We have 2 of the MarsHydro 600 watt grow lights.
The soil we use is a blend of compost, and Miracle Grow Performance Organics. We use Jobe's Organic Blood Meal fertilizer and also Jobe's Organic Bone Meal fertilizer. Our plants are in 10 gallon grow pots. We fertilize them with 1/3 cup for each plant.
wait ,mg soil does it have slow re
lease nutes in it?compost straight nitrogen good stuff,then you feed with blood and bone meal i asume top scratch it in?why?
next 10 gal pots,1/3 rd cup of blood and bone meal right,thats about 2 tbsp each of them right,oh no cant do it,if you scratch in 1 tbsp of each about once a month wouldnt be a problem bone has phos in it but is really for k side values,best way tom use your feed is cooked into the soil before you plant like about a month before,your locking the plant out from over ferting the plant like as in steriod injections,if im correct bone meal only has i think 12% imediate avaiability blood is a straight shot,compost is mainly n and then you have the mg soil,so ton of N,ton of N with only a tad of K and P,okay your locked ,then locked up plants thrown in dark for 2 days,which is probally only thing that has saved them from not stressing light if you dig,is there any wind movement in dark period?
the leaves that are jacked wont come back,doesnt mean you have to cut full leave off just bad part,if it were me i would turn that light back to 18-6 to you get it straighten out,do a slurry test on the soil,see were your ph is,im willing to say your probaly running around 8 thats the burning from alkaline soil /bone meal,that mg soil has slow release nutes in it as long as they are there your doubling down with food and that burns um,like aqua said look dehydrated all this fall right back to same thing locked,when you feed again give the healthy drink,start with cup at a time to you get the first sign of runoff,imediatly take that runoff and do a ppm or ec check,then use same runoff to check ph with your pen
