Hi, getting worried about my AK48, there are brown spots on many leaves and they getting yellow and many leaves, both young and old, falling off! Lots of flowers thats getting bigger! Soil is standard from a gardencenter, i use Canna bio flores 6ml/1 1/2 litre and BioBizz topMax 5ml/1/2 litre. Indoor in soil. I water it 3-4 times a week, light is two 125w le-lamps.
Is there anything to do or should i just let it be and hope for the best?

Here are some pics.

Fan leaves turning yellow is normal during final stages of flower,looks like could be to much phos if there getting reddish.Fan leaves are using up last of the N,nute and will yellow.Be sure to look for mites,and little black spots on under side of fan leaves.Overall dont really see a major issue.
After a closer look at leaves looks like phos,and nitrogen.How long till there ready.IMO id use just plain PHd water for a couple waterings getting ready to flush em! Great grow BTW.

red/purple stems means too much P? more like def/lock-out causes that. that is not a normal yellowing of ripening. watch what ya tell people.

Just saying too much p has done that to mine.I was talking about the rusty leaves anyway,but agree it does have a nute lokout IMO.A little calmag should help it really doesnt look that bad.Some of my best had red r purple stems guess they had nute lock?

PH water and water just as you have been if they have done that good watering schedule is Fine.Watch what YOU tell ppl.You even should know if he watered like hes doing, water is not the issue.PH water and flush if doesnt look better might try some calmag.Betcha dont loose it.

Nute lock, def lock, is it when the plant no longer take in nutrition? Calmag is it calcium and magnesium? Sorry many questions...

Hey there, I'm pretty new to growing (on my second grow) but I would suggest either checking the pH and doing a flush with some distilled water. I feel the latter is best out of two of course. I had the same issue with brown spots on my last grow, literally two days after i flushed the affected plant began to look very healthy with the new leaf growth.

It looks as if you have nute lock out with would not surprise me if you have never checked your pH. Brown spots are a sign of calcium def, which can be caused by pH being too low.
I had the same issues on my last grow. Invest in a cheap $10 liquid pH device so you can check your solution/water before feeding plants, this will give you a general understanding of what possible problems could be. I learned a ton from my last grow and my current grow is doing awesome relative to the first, and all i did was learn to balance my pH cause it can really fuck up your plants.

Long story short:
get a liquid pH tester on the cheaps or a henna one that 200
get some cal-mag+ and a pH up supplement so you can regulate the pH and give some micronutrients.

I have a lot of experience with this strain and Canna nutes. I would back the nutes off half as much. Dont keep a watering schedule, only water when they need it (let the soil dry out, not to the point the plant is wilting, but just before that). I looks like your in week 4 ish. Did you feed nitrogen during the first two weeks of flowering? If you didnt, thats why your getting an early yellowing of the leaves. I've experimented both by giving nitrogen during three weeks of flower and also by not doing ANY nitrogen. The plants that recieved N for three weeks, finished flowering with a full set of green healthy leaves. The plants that didnt recieve any N for flowering, had almost no leaves left after they finished. Both smoked great! I wouldnt worry to much, your plants look great! Right on par with the way all my AK's have looked. Also a side note, Ive had much success plucking the bigger fan leaves off of the main stalk. Maybe the top 5 biggest leaves off the main stalk. It seems the lower bud sites plump up more by doing this. Yes, your plant growth will slow for a few days (I doubt you will notice) but its worth it in the end. Your plants are just experiencing early nitrogen necrosis.

No nitrogen, only used Canna bio vega and Canna bio flores with BioBuzz TopMax. I have waited with watering until the leaves start to hang a little and the soil feel dry, no direct schedule! So half as much nutes, pluck fanleaves, I will do that :) next time nitrogen! Now I can cool down, thanks a lot! What You think about flushing with Canna flush?

You have learned alot,It takes effort and study to get the very best.If your grows and yield are not improving Read and find out why,I learned 10yrs ago how to grow and still learn to this day.Its part of what keeps me growing, cause after yrs its boring it your not trying new stuff are getting better yields and taste.Cheers BEECH.

I just get at hydrostore called Calmag.PH inbalance can cause lock and def.not allowing plant to intake nutes whether there the Micros,are the Macros.I use Horticulture Molassas for Micros just follow directions,also use in flower adds Taste just dont over do Are you will overpower the weed with the Molassas.

PLZ go easy on the FAN leaf plucking,the plant needs em!!!!Ok to do a few just for light pen.Ive been away for over a yr so dont quote me,but if i remember correct has something to do with Photosynthesis.I do know for SURE there very important.

Back off on water and any nutes you use, they could be affecting the poor thing, and anyways your clearly in the flowering period so i think you can afford to lose a couple of leaves haha.
