Stop using top-max. That has fulvic and humic acids which chelate the nutrients and makes it much more available to the plant. According to the biobizz feeding chart, top-max should be fed 1ml/lt from week 1 of flower till the flush. It burns little plants very easily.
Flush your plant. Use 3X the water of your pots volume. Let it dry. Feed 1ml/lt grow and let it grow out of it.

Also when you transplant into a bigger pot add perlite. Like 10-20% of the mix should be perlite/lavastones/pumice/zeolite. You can use them in any combination or just one of them. Just make sure you have enough in there.
