I know that nobody agrees with me, but I still think the plant is slightly under fed and not the opposite. I have overfeed plenty of plants and there is usually less uniform yellowing and the burn will effect the top leaves as bad or worse than the lower leaves working in towards the sugar leaves eventually. This looks like a pretty uniform deficiency of all macro nutrients to me.
Grow dots say PK shouldn’t kick in till day 45, so if they are burning plants by day 30 the guidelines are completely useless.
I did a grow in a 10 gallon SIP with the medium 10 gram/gallon dose. The plant was showing mild macro nutrients and calcium deficiency before flowering even got started. I pulled it off the SIP and watered it with liquid nutrients at .6-1.0 EC for the rest of the grow and the plant did great after that, yielded almost a pound of very nice flowers.
I am not trying to stir the pot, just offering an alternative perspective from a recent experience. I think watering in something with a little added NPK would get her perked back up in no time, just my 2 cents, if it’s worth that.
good luck!
