Seeing how Iām a hydro grower, I go about pH and ppmās a little different only because hydro has direct access to the nutrients.
But, the plants from what Iāve noticed and the way other soil growers water and feed will react about the same way, maybe slower in soil.
Seeing how being a new grower, with all the new terms, different things to know, can almost be overwhelming. Developing good watering habits when using soil is of the utmost importance along with nutes and pH. All of this will come in time.
It does look like some inconsistent watering from your last couple of pictures. Although soil growers tend to water, dry, water, knowing how much water comes in time.
Also, having a good reliable pH meter is supper important. We can usually get away with a cheap ppm/tds meter but not a pH meter. Hopefully you have that covered.
Overall, I think your plant looks great! No need to panic. I canāt say too much more than what @Caligurl and @merlin44 have already said. They would be whom I would go to if I needed help with soil grows, as well as other issues.
Keep in mind, when a plant goes through a transition from veg to flower, the roots grow like
crazy. Itās not uncommon to get a blemish every now and then. Sometimes a plant may outgrow the amount of nutes it can take up, resulting in a deficiency or two.
Based on numbers alone, provided you have a good pH meter, your numbers are telling me sheās hungry. I donāt know your previous readings but if they were higher and theyāve dropped after you watered, Iād say time to feed if you havenāt already.
Watering at a higher pH will do the trick to bring up your pH like merlin44 said and knowing numbers of your soil like caligirl said will help as well.
Good luck and keepāem growin!
