last try. please help

this is my last try to seek any help. i have seen new colors pop up on the leaves, so i'm trying one more time to try to figure out what's wrong. my plants just keep getting more and more yellow, everyday i notice more yellow on the undergrowth. she's lost 5 leaves in 3 days. my two autoflowers, are 4 weeks and 3 days old. this is my first grow and i got a little excited about the nutes and stupidly gave them some at 13 days, i burnt them. since then their health seemed to go back and forth but now it's going really downhill. the crystal, my larger plant is very droopy, it use to be that she perked up a bit after a watering, but now, nothing. her leaves are very crispy, very thin and will break if you touch them too much. my smaller one, skunk #1 has some yellowing leaves but other then that she looks healthy and for the most part happy, just very small. i'm worried about them, i thought the yellowing was from the nute burn at first so i had only been giving PH water, but apparently that's not how nutrient burn looks. not too long ago i started another forum and people told me that it was a nitrogen defiancey and she was starving, so i gave them both 1/4 of a gallon that had 2ml of BioMarine NPK 2-3-1 (recommended start dosage is 5ml), and it didn't fix anything, at all. so i tried again and gave her 2ml of BioThrive Grow (4-3-3) my soil is pretty woody, and i'm afraid some of her soil is staying moist while other parts are drying out very fast, like some sort of a drainage problem. she has kinda a weird smell coming from the side of her smart pot, i'm afraid it's root rot. her new growth seems to be doing great and she's got buds forming but i don't think she'll make it to harvest. i'm using new soil next grow (next week) and ive mostly came to the conclusion that this grow was a fail, but i still would like to get some buds because of how much i payed for the seeds, i don't want her to shrivel up and die before i can harvest. here's some information, please help



germinated in soil.


up until 13 days old i was keeping top soil moist with spray bottle.



water schedule


5/7 - .5 gallon Grow 1.5ml BioRoot 1.5ml BioWeed 1ml CaMg+ 1ml Diamond Black 1ml



5/10 - .5 gallon Root 5ml Weed 3ml



5/16 - 1 gallon flush PH 6.0



5/19 - 1/4 of gallon PH 6.1



5/21 - 1/4 of gallon PH 6.1


5/23 - 1/4 of a gallon BioMarine 2ml (moistness meter was on 3, but i was told they needed the nutes)


5/26 - 1/4 of a gallon BioThrive Grow 2ml (soil was BONE dry)



i wait until my soil moistness meter is on 1 to water. but i mostly rely on the finger method


my soil PH meter says PH is at 7.


Whitney Farms Organic Potting soil(.15-.10-.10)


10% perlite (yeah, i know, root rot?)


General Organic Nutrients: BioThrive Grow, BioThrive bloom, Diamond Black, BioBud, BioWeed, BioMarine, BioRoot, CaMg+


74-82'F


45-60% humidity


2.5x2.5 space


1 oscillating fan on high (they sway)


1 fan pointed at light


1 humidifier


400 Watt MH w/ wing reflector about 18 inches away up until yesterday, when i switched to a 400watt HPS w wing reflector, put it about 24 inches away, and i'm slowly lowering it. now is 16 inches away.


first thing i ever noticed on her was these spots

its now dead

a lot of her leaves have died at first i hadn't noticed anything other then them yellowing in patches all over the leaf and eventually turning completely yellow, but now i'm seeing these marks, some are a blue hue, some are brown. it could just be the leaves dying, but i wanted to make complete sure. here's the plant
here are the leaves yesterday as you can see, they are dying very quickly

Out of those nutes what have you fed her?

With autos I like to use veg nutes all the way through. At least until the stretch is over. It extends the veg time on them.



Using bloom nutes at first sign of flower can put them I to flower faster.


Quit using a moisture meter. I tried one and had problems the whole time.

You have several problems. When you water, water until good run off to prevent salt buildup.

Its starved of N. Feed it some grow.

You also need to water more. You have symptoms of chronic under watering.

The damage is done. Just correct it from here on out and let it finish.

here is what i've fed and watered.
sprouted 4/24, kept top moist with spray bottle until 13 days old;

5/7 - .5 gallon Grow 1.5ml BioRoot 1.5ml BioWeed 1ml CaMg+ 1ml Diamond Black 1ml

5/10 - .5 gallon Root 5ml Weed 3ml (got nute burn)

5/16 - 1 gallon flush PH 6.0

5/19 - 1/4 of gallon PH 6.1

5/21 - 1/4 of gallon PH 6.1

5/23 - 1/4 of a gallon BioMarine 2ml (moistness meter was on 3, but i was told they needed the nutes)

5/26 - 1/4 of a gallon BioThrive Grow 2ml (soil was BONE dry)

what's your advice to help her from here?

Just take Whitebb's , advise , he's on the money

are those blue/green and brown marks just from the leaf dying? kinda weird

Are you watering until the pot is wet right thru then letting it get quite dry and the pot feeling very light when you lift it before watering again? It seems from your schedule that you are watering too little, too often.

Your plant looks like it's well into flowering and a lot of strains start yellowing the fan leaves by week 5 of flowering unless the nute levels are high and even then some yellow. The different colours are just like fall leaves on the trees as they are getting ready to shut down.

What water do you use and do you know what's in it? PPM, minerals etc. A lot of time tap water can really screw things up so I only use RO water. My water is shit from a dugout on my property. We buy RO for drinking and my plants.

Good luck!

i use this tap that's been sitting out a couple days, the PH is about 8. i PH the water down unless i add nutes. i don't have a ppm meter so i'm not sure. and yes, i always make sure that the pot is dry before i water again, my leaves are very droopy, but i'm almost positive it's not overwatering because of how thin and papery they are. i always make sure i see some run off, i use to give them half a gallon but another grower told me that was too much for her size. and yes, i have considered that the RAPID (when i came home earlier i lost another 4 leaves during the day) leaf loss could be because she's in flower, but it just doesn't make sense how she's got so many pistils at 4 weeks old, she still has 5-6 weeks left of life.

Don't listen to that "other grower". You're pot should be almost bone dry (light as f@#$) before you water. Then, you want to water it completely until you get to about 10% runoff. IE: 5 gallon pot = 1/2 gallon runoff

Also, moisture meters are junk. Tried 3 brands. Bone dry sand reads as moist as does dropping it in a jug of water. I could not get even one of them to read "wet" no matter what I tried. lol. Go by weight of the pot.

i'd guess you flipped to flower nutes too soon, you have to let them get over the stretch and actually see the buds start to set before you switch to flower nutes, they're growing like hell, and will eat all the stored nitrogen they have, unless you give them more during the stretch period. then you get rapidly yellowing leaves, because thy no longer have any N in them, and the nutes you're feeding now have very little, if they're typical.

Its chronic under watering. Water them damn things. Like a couple gallons. Every time. I bet the soil has dry pockets that went hydrophobic.

Throw the moisture meter away. Water more 2hen you water. Water a little and ten minutes later water again until 20-30% run off.

You are not giving enough water when you water. Hell what you call flushing is not flushing. That one gallon of water was a normal watering. Get it? Water more.

i haven't used any flower nutes, but thank you.

towards the end of the plants life it is normal to have yellowing and dieing leaves

she's supposed to lose 14 leaves at 4 weeks old, with 5-6 weeks left? ha
