they are at day 48, i have had problems with PK deficiency before and treated them for what I thought was nitrogen deficiency which seemed to have stopped the initial problems. In the last week they have been on half strength Medi-one with some AN over drive, but I am puzzled as i have one plant which I took out and put in front of a a south facing window for a couple of weeks before returning it to the tent, where in 4 or 5 days it has gone from perfectly healthy to being afflicted with the same problem as the others.
When I was having the previous problems I turned off one of my 3 LEDs incase the effect of too much light had exacerbated the problem with nutrient deficiencies and after the problems stopped getting worse i turned it back on. At the same time as I returned the. lone auto pounder to the tent.
My Ph has varied between 6.6 and 6.7 and I use tap water oxygenated for 24 hours before being used
I think perhaps the first thing to do is give them a good wash through tomorrow morning and try and clear the soil of nutrients
Yo Bro,
It all looks good to me mate, as fatcalvin said, the bigger leaves will yellow and drop off, im intrigued to what LED's you are using tho, they wont do that to your leaves that's for sure. the worst ive had is bleaching of the top buds pure white.
So im guessing its all normal mate and that last picture looks well nice, buds look nice n fat.
They normally take a week to recover from anything drastic anyway.
I wouldn't bother with the flush, just give her pure water next watering, nothing else and watch her pick up.
Plus pick off those really dead or yellowing leaves, it wont hurt her aslong as they are fully gone...it'd put ya mind at rest when you look at them next.
Plus a 'watched kettle doesn't boil any quicker'
Patience is a virtue in growing...
Best of luck mate, keep us posted!
Green Karma coming to your ladies right now......
