2nd grow same problem!!

I totally agree with blitz about this being a nutrient deficiency.

bro this is not light burn..your humidity should be maximum 55% in flowering...65 is a way too much...additionally i would suggest to you to use coco coir..u can control the media much easier than soil..this problem is definitely nutrient deficiency..if u use soil it could also be overwatering..with this way u lock out the root zone and after this u cant do many things to fix this..after this if u let it dry..your soil is gonna be like a rock..the plant wont receive anything..just start using coco coir bro..you will thank me later!

I agree it's not light burn but your humidity can be higher it's best to follow VPD I used to keep the humidity lower but I've had much faster growth following VPD

i think it's nutrient defiency. why? leaves look super dark thus indicating nitrogen toxicity which leads to nutrient lock out. your plant basically isn't getting proper nutrients because your feeding too much nitrogen or too often basically.

i do NOT think it is a humidity issue trust me i run grows in high humidity at the very least it is 60-65% can go anywhere from 60-84% though and they do NOT show these signs. it is best to keep humidity lower but im 100% it is nutrient lock out due to over feeding nitrogen. you can even check out the daily temps/RH for my grow they are not optimal but you do not see these signs. they do have slight nitrogen toxicity showing with darker leaves and slight clawing but not much burning going on. i literally started to feed less often as well and drop anything with massive amounts of nitrogen down in the feed schedule

This far in flower IMO “ correcting “ any deficiency is kinda moot. She is not going to magically get picture perfect. There looks like bug issues ( spots ) which stresses a plant also , as the little fuckers suck on it .

Large amount of pistil change , foxtails, .... so she’s getting to close to end for any real help.
Run her on water only till end ( no bloody flushing , runoff bs ) .... PH @ 6.3 ( what FFOF is ) .
Allow the plant to pull ONLY WHAT IT WANTS from itself and already “ charged “ FFOF.
Tiger bloom is very strong and adding on top of a hot soil like FFOF is what screws autos every time.

FFOF right out of the bag can carry a plant ( with NOTHING else ) for 6 weeks easily. Just ph water.
Autos short life falls favorably into this MEDIUM ONLY FEED regime. By allowing the plant to fully
acclimate to a unmodified medium like FFOF .... without adding ANYTHING but water , your plant will not be overwhelmed as it has grown accustomed to the soil. Then , if you want at say week 4 / 5 of flower you can add a small PK boost ( if you like ) .... like big bloom which is an organic .

Or even a bit of kelp into the watering .... which aids in plant stress , growth and vigor.
Kelp has natural sugar to metabolize the soil ....

Next time ... run it on water only and see what I am talking about.
It’s heavily ammended .... perfect for autos.

Ok, the veg phase goes near perfect, no yellowing or brown spots. It all changes during flower, I figured the flowering stretch gets the girls to closeto the light, I always wondered how all these growers ate growing with multiple 300 watt leds or even bigger in a small tent without burning the plants, guess I was wrong about the burn, thanks

I read the thread a few times but felt like this was your problem - you lost control of ferts at transition to flower.

Wether through repotting or simply discontinuing veg ferts or even mis judging the strength of the soil. I get the same happen occasionaly and from one reason to another what your seeing is deficiency.

Your buds look great though. Knowing your soil and ploughing through these transitional periods in the next grows will sort this out.

I myself just use a balanced fert start to finish, blooms are last needed get a full fert or use grow and bloom together or even just grow right into the first half of bud formation at least.

This is loose info but i feel more grows and practice plus if you get veg perfect its only a minor problem flowering didnt follow suit - obviously you got it mainly right as you got bud so look to those little things that throw you off

How can I supplement cal/mag without giving the plant to much nitrogen during flowering? I only give half a dose but my supplement contains nitrogen also.

im not keen on the whole cal/mag stuff since i don't use it so i didn't really research much about using it and all that but MANY growers here use it. you just buy Cal/Mag it comes as a supplement there are MANY different brands idk which one is the best or what not so try ask around.

AN has one i know GE also has one i think it is called Cali Mag other nutrient lines have their own usually. it's one of the easiest supplements to find tbh

Botanicare Calmag
Gh has calimajic
Advanced nutrients has sensei cal-mag xtra


theres others out there too, every weed nutrient brand has a calmag line i think lol

Epson Salt for your Mg
Calcium Nitrate for your Ca...although it does impart some N.

I personally avoid the marriage of Mg and Ca...as in CalMag.

Good luck...

That's because it's a softpot. They dont allow the water to really get to the dirt before the cloth sides leak it out.
My hard pots I'll add a gallon of water, wait a couple min and add another gallon of water and still dont really get runoff. Anything over 2 gallons runs out however.

Use a bamboo skewer or a knife to aerate the roots regularly. All the way down to the bottom. Your water will reach it.
