Try to cut back on your feed, the outdoor picture also... You said itโs been raining and getting a lot of water! Did you feed when it was already wet? Cause this can cause issues in the Rhizosphere/ roots lol Yeah itโll burn them! So that discoloration is your plant telling you hold up let me correct whatโs going on! You think somethings wrong so you try to fix it and make it worse! Trust me it happens to the best of us! Just cut back is all great job too! Also before I forget smoking and writing can affect lots lol... Yeah so add Calcium in the morning and at night! Calcium is crucial for cell division! Take care and happy growing!
