Ditch the shade cloth. Like I said the plant likes and can handle full sun. Its a WEED, weeds are resilient to all growing conditions.

As for the new growth. I'd discontinue all nutes, water with plain Ph'd water for a week. Then start the nutes again at 1/4.

Maybe let the medium dry out a lil, so the roots find the bottom of the pot.

Its all trial and error. Take it in moderation.
