Browning and drying leaves. Day 43 of flower, first grow ever. Defoliated yesterday and didn’t notice any of this. I have 2 other plants going but this is the only one showing this. I have no clue what do do or what’s causing this. Please help!!!
Without diary or any history its a shot in the dark.
Looks mid-late flowering plant, with big nutrient deficiencies. Likely caused by either a pH problem causing nutrient lockout; or from not giving them enough nutrients in the first place.
If pH is 5.8-6.3 you are good. Flowering likes the higher end but the odd 5.8 watering helps let the other nutrients in. Try this first before adding more nutrients.
