Yellow lines on 2 leaves Any clue what this is? About to be week 6 and in flower. I'm thinking the start of nute burn? I gave it bloom boost in the last 3 waterings in less and less amounts. let the soil get very dry before watering with plain 6.2 pH water. Any input is appreciated

Did I give too much fertilizer??So I decided to add in some soluble fertilizers. I gave it a 1/4 tsp (50% of recommended dosage) a couple days ago and noticed some yellowing of new growth on the bud sites. Is this a sign of excess potassium and phosphorus? I gave it Fox Farm Open Sesame (5-45-19).

Yellowish Spots on Fan Leaves The fan leaves on one of my plants are getting yellowish spots. I noticed it yesterday and checked the pH and I was at 5.0. I corrected it to 6.0 and 24 hrs later still 6.0 but some of the larger leaves are starting to show yellowish spots as well?

Yellowing leaves.Yooo! I have a few lower leaves starting to yellow I’m pretty sure its because the plant has switched all the energy to bud production so my question is, is it ok to defoliate the yellowing leaves at this point?

Name the deficiency.Problem is mainly occurring on leaves near the top, but not the newest growth. Initially are less green, then start to yellow followed with brown spots. The oldest leaves near the bottom are seeing some effects, but as acute as the mid-upper leaves. Curl likely due to warm temp
