overdose?

[JonnybeGood]

the tips of most the leaves are slightly curled under. also the tips are slightly burnt. it isnt bad but i dont want it to get worse. Could low humidity cause this?? cuz its only 30% or so. temps are 78 daytime and 60-65 nighttime.
there is no ph spottin, i keep a steady 6.1 ph.
30 mL of PBP every feeding, once every 3-4 days.
promix bx, 3 gal bags
strain- cherry bomb indica

overfeeding?
opinions welcome

peace

low humidity would cause the leaves to curl upwards downwards and under is moisture stress.

They would also use up slightly more water when humidity stays lower.

THat is cold at night time you wanna stay in the 70's if all possible.
Need more grow information>

wth! 30 ml of PBP every feeding? With how much water???
How often are you watering them between feedings?
pics would say a thousand words.
How often are you checking your ph run off? what are you using to test it with?

 

[JonnybeGood]

30 ml/gal- as directed.
and i thought temps 60's were ok and cooler temps will cause the genetics to express themselves moreso.

havent been checkin runoff ph, but i water with 6.1 every time.. and i have a ph truncheon. no signs of ph probs i dont think.

and between feedings i dont water them.. every 3-4 days they get fed cuz thats when they are dried out.

Yes, but that is only if the strain has the gene to change color. When you also get low temps that can cause slower growth and lost yields in flowering. I bet any thing they are overfed; that is a high dose to be feeding them. THey would have to be like 5 feet tall to give that strong of a dose, even then if the strain has a high tolerance to nutes that would still be over doing it.

How big are these plants? Can you get pictures?

 

[JonnybeGood]

it is 17'' tall and i dont want to put pics on this site.
but i think your right, ill back off on the nutes a bit..
the dosage hasnt seem to affect my other cherrby bombs thou, but they are all from seeds so diff phenos, diff feedin levels.

ok well good luck with your grow man.

Just as a reference...

Pure Blend Pro Bloom Soil
1.5-4-5
1.0625 grams/ml
@10ml/Gal
N 42
P 49
K 116
Mg 14
Ca 28

30 ml per gallon is too much. K would be 348! Try 15-20 ml per gallon. Be sure to get alot of runoff to prevent salt buildup.

Night temps are too low. Water becomes too sticky. This causes deficiencies to occur.

wth dude 15 ml a gallon is still to much man he would still be burning them.

wth?????

 

[i love herb]

start with 10ml per gallon of pbp bloom and work your way up to 15... 20 IS MAX!!!!!

 

[JonnybeGood]

well the pbp i use is for soilless and hydro( i grow in promix bx). its NPK is 2-2.5-5
and it says use 30ml/gal for flowering and 45ml/gal for large plants..
i dropped down to 15ml recently. no signs of burning.
and BalckVelvet, dont even bother feedin me your BS.

ill try to increase the night temps stitch
and thnx for the advice.

peace

Most directions on the nutrients are bunk and 8 out of 10 times it's to high so you want to always start half of what it says and then go from there... so pretty much that is what you are doing

If they are still burning with that chuck it down to about 10 or 11ml
