GORILLA GLUE (week 8 of 10 / day 59):
Four plants in here, all from bagseed, just one showing any hermie traits and although I have been plucking off occasional ball sacs I have also squeezed a couple of seeds from its flowers so I know it did manage to self pollinate.
I've not found any other seeds when gently squeezing random calyxes, so hopefully this was a contained event. The buds haven't swollen on this one much.
A totally different one of the four has had problems the past week or so (front corner of pic above), with big fan leaves feeling dry and brittle/crispy and increasingly pale. Feed has been consistent and so presuming a lockout I ran Dripclean through with the last res change to wash out heavy salt buildup in the medium.
Sure enough I can see thick white deposits on the hydroton layer in the table. Some color has come back into the leaves but also some burned tips. Feed has been rolled back by 0.3 to 1.3EC and I will continue to fade slightly to end now.
It may just be finishing but it seems a little premature with 3 weeks to go.
I have to check my DIY halo drippers every few days as they easily get clogged. This a combination of heavy salts but also staking them close to the medium and coco or rockwool getting in the way.
Drip Clean takes care of the salts but seems risky introducing it mid run and should be added from the start I think.
I read something about snipping the very tops of buds to encourage them to fatten up, and feeling like I had nothing to lose I gave it an isolated test on 3-4 colas of one plant. No difference noted.
Stoner myth?
A few things i'd like to improve over future runs:
- Getting feed levels dialed for every strain = zero burn or lockup
- Keeping the lower third completely barren and reducing popcorn / larfy branch crap
- Definitely scrog everything
- Including Drip Clean start to finish
- No more rockwool
Another thing I want to work better is the Quest 105 dehumidifier. I have it on one setting around the clock, and have not tried changing it for day/night, nor is it practical to do so.
Seems night time in flower can peak up at 80% (at 63-66F). I currently have no way of tracking when or for how long, just a max reading, and I feel like this could easily be a limiting factor.
I observe no issues such as PM but since I am not reclaiming anywhere near as much water as expected for mature plants I know transpiration is less than optimum.
Perhaps a higher RH at low temps is comparable to lower RH at higher temps and is therefore nothing to worry about?
I did ask Quest directly and their only advice was to warm the room at night to 72F, but this would also require a manual change at the AC every day and it just doesn't work for me.
Any thoughts i'd love to hear them!
