Lots of changes this week. Kept going with LST, though stopped 'pony-tailing' so that the new growth can get more light exposure. This now shadows lower potential colas, but maybe worth it for now. Watering every other day approximately 800 ml.
Pros:
. White Hair pairs emerge! Thus we must be at least at pre-flower.
. Subtle smell of artificial Watermelon around mid-day when close. Otherwise the worm casting fertilizer odor masks any cannabis aroma.
. LST seems to be working great on 1 of the plants with lots of light exposure - hoping to get even height with all colas similar in size.
. New Oscillating Fan!
Cons:
. Deficiency (Yellow Leaves started last week) - Nitrogen (resolved with top dress and helpful GD member)
. Deficiency (Lime Borders on new growth) - Guessing due to having missed amending the soil during veg. After feeding, no further spreading has occured.
. LST on yellow leaves was going great, I forgot to restrain the first bend from last week, so she corrected this instead of maintaining shape.
. Third plant seems stuck in time, not much growth happening here.
. Checked soil PH (coco + perlite + dry amendments), which seems high (5.8, 6.9, 7.6)
. High temperatures incoming this week
@Hou_Stone, Thanks very much! I like the way you've hung your towels in your diary. I tend to just wrap my towels around the supporting frame/chassis of the tent, but having a line setup like yours is much easier!
Hi mate, if you find a way how to help the yellowing leaves let me know, I had the same thing just managed to stop it for a bit with PK but it was not a long term solution.
@Metatronix, You're welcome - I'll help in any way I can!
Interesting, I'll keep an eye on it and see how things progress. I defoliated the most offending leaves this morning, so any new yellowing should be easy to spot. I'm very intrigued, I just hope it's not a consistent problem.
Curious to see if the quality of smoke is greatly affected come cure.
@MMSC16, Thank you for the sum up bro ๐ I also see delicate signs of lights stress, just that it's nothing rough, the edges of the leaves just barely go up...the main thing has to be something else ๐ค
curious thing about overwatering could be, em not from that department but in my case as I wrote, my plants had very similar damage but it's hard not to overwater in DeepWaterCoulture ๐
I observe a growmie here who grows for years (uses the same nutes as me) Has similar trouble, he also can't put a finger on it...
@Metatronix, Hello! I certainly will - From what I understand from the community here, it's been a result of light stress and underwatering. I'm a complete novice - so take what I've learned with a grain of salt.
The cause in my case is likely as follows:
. Added an extra grow light in the same, very small environment
. Distance from light was ~13"
. Was watering every 2-5 days - coco requires more frequent watering.
. I also exposed my plants to direct sunlight in addition to the 2 grow lights.
. They're likely more resilient in vegetative stage to light burn, so symptoms only really arose as flowering progressed with final stretch.
As for the solution, in my case I've just been flushing with clean PH water and increasing freq. of water. Too early to see if it's working but I'll let you know as soon as I know more!
