Nice,these new LEDs sure seem to suck out the calmag from the top leaves.I normally spray epsom twice a week seems to help.
I had an EC spike in the rootzone which caused a slight pH issue I believe possibly causing uptake of Ca issue.

EC was going in at 0.8 and coming out at 1.4 so I knew something was going on.

it hasn’t really progressed since I stopped it only the existing leaves that had the issue are still there.

i put it down to a little too much MKP at the wrong time Along with possibly the brick coco I used and didn’t bother to buffer.

I was using between 0.2-0.4 EC of Calmag pretty much the whole way through but stopped until I rectified the issue which stopped progressing after I stopped Calmag.

next grow i won’t be adding Calmag and see how they fair just from the Ca and Mg in the base A/B.

Anti histamine taken ready for chopping some of these tops tonight.

delivery day of a few bits.

13mm in-line filter not for the fact it’s a filter but for quick disconnect of my tote from my delivery ring.

13mm ID ratchet clamps for the LDPE pipe.

and some citric acid.

Transplanted the BG41’s into larger pots.

Have added around 20% perlite to the coco this time as I want quicker drainage for when I setup the auto feeder for them.

The room is currently on day 80 I haven’t harvested any more yet as I’ve been a little busy.

Will be harvesting more tomorrow.

Little update of what’s happening at my house.

I think it’s about day 92 of 12/12 in the room.

blue gelato 41 have been topped now too.

All I have been doing is topping up with water during the last week or so just to keep the plant ticking while I’ve been progressively harvesting.
