Buds are feeling really dense and leave a wonderful smell on my fingers.
I believe I'm having quite a bit of a potassium deficiency, spotting appearing on the old leaves and newer growth coming through a little wilted and dark. I've used a small amount of PK booster but I'm probably a bit late to reverse the damage.
Finally got myself a jewellers loupe, only to find more thrich heads are clear than I had hoped. Couple of weeks til haven't hopefully.
Hi Gandalf, are you growing in coco? If so, do not let it dry out. It will cause your root zone ppms to go crazy which will turn into lockout/deficiency/or even burn. From my experience with coco, I never let more than a few grains on the top go dry. Coco is to be treated as a hydro system. Feed lower ppms at a more frequent intervals. Feed to runoff as well. I would recommend flushing your plants with half nutes. Check the initial ppm runoff to see whats going on. Ideally that ppm should be close to what your putting in plus or minus 100. If its significantly higher, keep flushing until you bring it down to range. Also, take a coco sample from deep in the root zone and do a slurry test. Take 1 part coco and mix with 1.5 part 0 ppm RO water and mix thoroughly. Set aside for 2 hours and mix it up again and check the ph. Make sure your in the 5.8 to 6.1 range better 5.9 to 6.0 to be perfect for coco.
This was my biggest "A-HA" in improving my grows. Lastly, your feeding ppms seem awfully low as well, most autos in flowering if fed once a day should get 500-800 ppm. I see signs of N, P, CA, MG deficiencies which will really hurt bud development especially resin and could lead to hermie as well. If it were me, I would flush the hell out of the coco until the rootz one ph reads 5.9 to 6.0 and ppms running off at 700ish ppm. Just trying to pass along some experience, not trying to step on toes. Best of luck finishing her out. Cheers!
@GandalfTheGreen, I use Troph Blumats. Depending on where you live, they can be found on Amazon. Make sure its the TROPH line. I place a 3 gal reservoir on a shelf about 5 feet above my plants to ensure good back pressure as its all gravity feed. It uses water filled ceramic plugs that sense the moisture content of your media and automatically opens and closes the valve at your desired wetness for the media. They can be scary to run as the valves can "runaway" if it wasnt set up properly and dump your res out within a few hours. If you use one, make sure you check it a couple times a day for the first week to make sure its dripping properly. I'm installing mine shortly. I'll put up a little video on the diary.
@Ga4rd2en0er, this grow really has proved to me how forgiving coco really can be! Do you reccomend your drip feed system? I love watering and inspecting the plants daily but I know after a few months I will value a slightly more automated system.
@GandalfTheGreen, from my experience, removing a few dead leaves shouldn't really stress her. Pruning dead leaves for all plants help them redirect their energy to the good parts of the plant. Once leaves are damaged that badly, they will never recover. Look at your new growth for signs of recovery. The fact that she perked up after a good watering is a plus that she wants to live.
@Ga4rd2en0er, definitely looks like she is getting her strength back. a more uniform green spreading back across the plant. Will trim those bottom yellow leaves off shortly! Are the dead leaves much less likely to shock the plant when removed? or is it just because i'm only trimming a couple of them that it isn't shocked?
@GandalfTheGreen, next step I would do is remove the few very yellow leaves at the bottom. They wont recover and could be pulling energy from other parts of the plant. Especially the ones that maybe laying down touching the coco. Just dont do any thing else other than a couple dead leaves otherwise it could lead to shock and she is very vulnerable until she gets her full strength back. Looking forward to seeing your next entry to see how your babies are recovering.
You can do a little lst by gently bending over the main stem. You can use twine or similar to gently pull over the stalk and it can be attached to something sturdy such as tent pole, a heavy weight placed on the floor, etc. Also. Watch the ppms feeding and making sure you get good runoff feeding. Looks like you may have the start of nutrient burn.

Other than that, her comeback looks incredible!!
@GandalfTheGreen, i have a bottle of canna pk and only have used it once. My last grow was having nute issues in flower so my focus was stabilizing her root zone so I didn't want to throw another cog in the machine. Haven't decided on what I'll do with my current one. I haven't used it enough and with enough consistency to really make a recommendation on it at this time.
@Ga4rd2en0er, i've lowered the feeding ppm quite a bit as of last feed. I'm not LST'ing this one as the stems pretty thick. I've just adapted my grow space and gained another 25cm. If it stretches to that then I will have to no choice but LST!
Thanks for all you help. Do you reccomend flowering/pk boosters? Probably a bit late for me now anyway but I'm curious.
Amazing looking plant and a great journal. I have a Moby Dick heading into week 5 and sheโs a little bushy as I did lst.
Thanks for sharing and I hope mine climbs like yours!
Alright alright alright, she's turned the corner and looks back on track. Now, since she's gone through some pretty stressful couple weeks at the start of flowering, keep a good eye on her flowering sites. Its not a guarantee, but plants that have undergone high ppm stress can be prone to becoming a hermie. Keep a watchful eye for nanners or balls on her. If any nanners pop up, they can be carefully removed with wet tweezers (water neutralizes pollen), balls or actual pollen sacs are much more problematic.
Looking awesome, airy or dense it all goes to the dome ๐. Congrats on a job well done adapting and overcoming along the way. The key to success!! I can't wait to grow her again either. I hope to grow her outdoors next spring/summer and see how many pounds she can make. I have no doubt with these genetics and proper care will be huge outside basking in the So. Cal sun.
Now that's one impressive looking Moby Dick Auto ๐
I would start reducing feed mate in preparation for harvest in 10-14 day's time ๐
Looking fantastic my friend ๐
All the best โ๏ธ
