Good morning starting to have a issue with both blue cheese. Yesterday was feed day. I had to go to a BBQ so I mixed up the nutes before the lights came on and quickly watered all of them soon as the light clicked on before leaving.
When I returned and was looking them over I noticed some rusty spots on a leaf on each of the Blue Cheese.
This is What I think is going on you might remember not to Long Ago I dropped there feed to 4.5,gm/gl from 5gm because I could see a nitrogen toxicity starting. To dark of green colour downward clawing leaf tips. Classic N toxicity. After 2 feedings. At 4.5 things seemed to be improving so I increased the feed to 4.75 gm. Yesterday was the second feedings at 4..75. If I had not been in hurry to water last night I probably would of noticed the darker green creeping back in an the spotted leafs and would not of fed them the 4.75 and would of lowered it probably another.5 gm.
My take on this is K is starting being locked out also possibly a Mg defficiency from to high of N.
Blueberry#1 Ca defficiency Is slowly spreading it is on its second watering at 5.5gm I had raised itt because of the Ca defficiency I will monitor and possibly increase to 6 gm next watering. This one had used more nutes than the rest since day1. Blueberry# 2 looks good at 4.75gm. I should mention I am on a 3 day watering schedule giving them all 8 Lt and getting around 15-20% runoff.
I had a bunch of pics I took last night but I am having problems getting them to load onto the computer. I have a few that I took with my phone because I ran out of memory on The camera.
Blue Cheese#2 Both pics of same leaf about 60 % from the bottom of the plant
Blue Cheese#3 Both pics of same leaf about 60 % from the bottom of the plant
A couple of other possibilities. Could this be related to me not adjusting the PH level? This is a first for me. Also couple weeks ago I introduced a led light into the mix exchanging it for the 1000 watt HPS.
If anyone had any thoughts on this I would love to here them.
Happy Saturday wake and bake time
