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.

Bottom leaves yellowish - why? And can I top?On both of my plants (C99 & S.A.D.) the bottom leaves are turning yellowish and I can't figure out why. I'd also like to top them this week (above 3rd node), but I'm hesitant because of the leaves. Any advice on what they may be missing, and whether I should wait with topping?

Seedling Light-burn or Toxicity Hi growers! Is this Light Burn, or nutrient toxicity from nutrient dense soil? 2 Mars Hydro TS600 lights at 27" from seedling. PH 6.3 misting soil - RH is 75-80%. - Temp is 77F No light meter, so I estimate PPFD is in acceptable range despite using 2 lights in 2x2 tent.
