They shouldn't.

Are you watering until 30 % run off? If not you are getting salt build up.

no they're not and watering until you have 30% run off is over watering and if you have salt build up you are over fertilizing and wasting money and fertilizer. . autos don't do anything normal.

Anything in flower needs a full nute regiment if you want real growth. Honestly with that light, and the size of that plant, there will be a very small yeild. IMO feed that bitch as much as you can til you see tiny burn at very leaf tips.. full bloom in soil im at MINIMUM 1300ppm

hey buddy thx for the info, its growing under 600w true draw (800 hps equalentish...) i m feeding pretty hard on em too, i ll keep pumping up the nutes. Btw how long do u water them? Mine usually dont show sigh of thirst for 5-6 days.

Hey manthx so much for the info!!
I m feeding half the recommended dosage, which i guess is strong nutes for autos. If its a built up should i flush with just plain phed water?

And btw they are still veging autos dont stop vegging til around week 6 and they vege and flower at the same time too, its kinda awkward but it speeds up the process

Wrong. You have to water until good runoff to prevent salt buildup. Good run off is not over watering.

Fact is you telling the guy the yellow is normal is wrong.

All 3 are autos and green to the end. Help the guy figure out what's wrong.

The. Yellow you see in the pic is a photo plant I was getting in there and it got root bound.

It is not normal to lose leaves early flower.

They don't veg and flower at the same time.

The yellow is either from salt build up or from switching to flower nutes too early and they burnt through N during stretch.

Flower nutes will induce flower in autos. Run veg nutes all the way through for big autos or at least until stretch is done.

Just water only a couple times.

Are you feeding, feeding, feeding?
Try water, feed, water, feed, water, feed.

You do need to water until good runoff.

Follow that and the veg nutes until stretch is done and you will get bigger yield.



What have you been feeding?

Hey thanks again for the help!
I am feeding every watering since week 2 after germination, i feed at very light dose 1/4-1/2 recommended dose...

And here is the nutes i use, according to the company other than biothrive, anything else can be used from seedling to harvest... which made me suspective because some these nutes has high PK which i dont think is the best to get lot of during veg...
anyway here is the line up i m using.

If you are getting salt build up your soil is dead or you are over fertilizing. There's nothing wrong when an old leaf on the bottom turns yellows during flower. his new growth is green that old growth tells you nothing.

Looks like a single leaf getting old and wearing out. Everything else looks fine. I'd be giving half Grow and half Bloom with autos once they start growing buds.
