OG Kush Auto - Outdoor - 46 days - light yellowing at bottom leaves

[jayjay]

Hi there, these 2 OG Kush Autos are 46 days grown outdoor in smartpots fed with rainwater, organic molasse during vegetative stage and now organic molasse-flowering booster (starting almost 10 days ago). I wonder if this light yellowing is normal considering that the LST-one has almost no signs of yellowing and they are same age/same treatment. pH is around 6.5-7. There is a younger (37 days) Purple Kush Auto behind, same treatment, no signs of stress yet. I put them under greenhouse only when heavy rains, usually they are outside.

I don't want to stop feeding with flowering booster now because buds should be fattening now and I find them rather small.. but it's my first grow... what do you suggest ? wait and see ??

Those lowest leaves I wouldn’t worry that much.
Looks healthy and have a nice color also.
I saw some burned leaf tips, some places. Which could indicate you are feeding her a little bit too much.
if she is not showing any deficiencies, don’t overboard the nutrients. It will just stun her, if she gets too much..

nevertheless it looks healthy

Thx ! burnt tips appeared 2-3 weeks ago, I wasn't sure if it was because of excessive feeding or warm temperatures (we had 4 consecutive days of heavy heat). Will slow down feeding a bit.

What amazes me is how the one trained with LST shows almost no signs of stress whereas they are exactly under the same feeding schedule.

I think that they need more intense light also.

Thx ! because of its orientation, my garden is limited in terms of light; there are many shady spots during the day. I have to move the plants (like 10 feets away) 2 times a day to get the maximum light possible.

The photos have been taken inside the greenhouse. Is it preferable to let them inside the greenhouse but dry ? or outside and moist (when rainy) ? what do you suggest ??

[EDIT] I stopped feeding since last week. She is now 52 days old, so 4 weeks before her (theoretical) end of life according to the breeder. pH is still around 7. Yellow leaves seem climbing, I don't know if it is normal at this stage or if it is too early ? How could it be N deficiency since my pH has always been around 6.5 - 7. Thanks for your advice !

Even the same strains, don’t need the same nutrients. Even in the same setup

Those breeder schedules are for flowering - so one starts counting after they began their flowering. Some are done by 65 days tho.
I take those schedules with a grain of salt - let the trichomes determine how close or how far away from harvest.
Also - those times have been created using optimal conditions in a 3×3 tent. You're outdoors so add 10 or 15 days to that schedule.

I would say 15-30 days more outside.
My experience with autos outside

True what they are telling you jayjay FYI i just dosed my mag. defecency with epsom salts 1 per gal. yesterday they are looking real good today. It's a good thing for plants.

 

[jayjay]

Thanks for the advice... I won't worry about the yellowing yet and just keep observing. Will post new pics in a few days.

[EDIT] Plants are now 65 days old. I stopped feeding them 4 days ago because I think they are entering their harvesting window. and I plan to harvest in +/- two weeks. Should I be worried about the yellow leaves turning almost red ? or worried about these small leaves edges turning dark purple / almost black ?
