Hiyah fellow 420ers, I trust you all had a good one
. Time for a bit of an update. Its been 7 days since I changed the photoperiod to 12/12 and as usual the girls have started playing up. My PH is 6.5 I have not given them a feed yet, so I'm thinking its gotta be a deficiency. The cheese all went tits up at the same point in my last grow, so I reckon its the batmix running out of secondary nutrients. I proceeded to look through the deficiency charts on 420 and found that my leaves look damn like the magnesium deficiency photo's.
I have one plant though with instead of yellowing between the veins it was yellowing veins starting at the base of the leaf working its way out.
After much investigation and viewing many photos online I diagnosed that this was a sulphur deficiency.
The obvious next step was to get hold of some medicine to correct these problems so I got hold of some magnesium sulphate and have just given them 1tbsp per gallon in their water.
Fingers crossed this helps and I'm not barking up the wrong tree, time will tell, but I'm quietly confident that I have found my fundamental problem
. The bat mix just runs out of magnesium when the plants need it the most, and that's when they start to make flowers.
I was expecting a busy week of stretching, but they have been a bit slow this week so keeping the scrog in check was none to taxing. Hope they pick up soon.

Before lights on.
Lights on.
The white powder on the leaves is dolomite lime I dropped, don't worry its not PM.
That's it.
See you around Reg's tomorrow evening for the reps are right.
Have a cracking weekend all.
