Having some nutrient issues. A few leaves are yellow with brown tips (first couple pics). I also had some nute burn a couple weeks ago after switching to GH so I lowered my feedings. Now I’m confused if it’s an excess or deficiency or something else? Any help much appreciated

problems with low leaves
in the lower part of the plant some leaves are yellowing, others are drying out and even detaching. can it be due to the fact that since flushing (a week ago) I have not given anything to the plant anymore? I hope this does not compromise flowering

Grower question
Any ideas what the issue could be? Few weeks into flower. Dealing with fungus gnats and have kept the population very low. Temps do get high, at most 95 (hot I know). I cranked down the lights to their lowest setting (100 true watts LED). I have adequate air flow.

Is this nute burn or other deficiency? I did increase the feeding a bit. But also just came out of a calcium deficiency. Not sure if the one with brown edges was from before tho, I forgot to clip a couple leaves with brown spots

They were slightly overwatered, the soil PH of 7.1 to 7.3, lacking phosphorus, maybe magnesium to. Branches from the sides are stretching, but I noticed thet lower leaves started to turn yellow a little at both. If anyone knows good advice to help them out, I would be grateful.😅

Help me diagnose this color on my leaves. I don’t if it’s something to be concerned about I just don’t want it to get worse. Overall I think they look great. What do you think?

I probably have spider mites on my plant. Yesterday I sprayed it with Maag oil. Today I bought an organic product and sprayed it on the plant. Are the discolourations on the plant caused by the mites or burns due to increased light from the drops? Or a lack of nutrients?
