Salt buildup (root block) symptoms NOT fixed with flush

I’m growing those two strains indoors, both feminised and in the flowering phase. And using Two Phase Bloom with NPK (1.5 - 4.3 - 3.6) and gradually increased feeding 1/4 up to full dose.

Plants had low PH and very high EC and PPM, after two flushes EC and PPM is okay but PH is still low. Despite applying garden lime with natural calcium carbonate and magnesium, leaves increasingly having random washed out spots, some holes and very light burn on a couple of leaves. Help please! :smiling_face_with_tear:

Welcome! I wouldn’t be able to help you here as I’m a novice grower but there are plenty of experts here that will chime in soon I’m sure!

Honestly, it looks like thrips and/or leaf miners. Theres also might be a couple water spots in there

But i am not an expert.

I agree it looks more pest related than pH. What are you growing in?
