Dry yellow/brown tips, starting from the oldest leaves
robostarted grow question 4 years ago
What's wrong with the plant this week? Many leaves have dry yellow/brown tips, starting from the oldest leaves.
Is it some kind of nutrient deficiency, and how do I fix it? I tested the pH of the drainage water and it was 6.8, I've flushed it down to 6.2 now.

This is most likely caused by your ph being to high for coco.. Acceptable pH Range for Coco: 5.5-6.5 so you were a bit high.. hopefully correcting this will start to solve your issue! looks like you already knew! Happy growing!

You are having a nitrogen deficiency. Check your ph levels to make sure your not locking out any nutrients 👌🏾

had it previous week a bit too and progressed, so i'd guess imbalance causing lockout or too many nutes to me. 5.5pH is probably a bit low, but depends on your fertilizer's instructions.. mine says 6-6.5 range is optimal. Get that fixed and easy up on nutes in meantime.. if pH clears it up, slowly resume and you'll soon learn if it was pH or nutes.

Slight leaf tip "burn"What do you think is causing this burn on my leaves? It seems to be quite common. and maybe nothing to worry about if it's this minute. but I would prefer to not burn my plants at all if possible. Could it be a sign of underwatering? Light distance? i have a dimmer keepin at 1000a year ago
