Nope...it's not mag def. Looks like a potassium issue IMO...what's your TDS/EC level?

 

[Guest]

1500ppm
I will do a serch on that thanks for your opinion im betting your right. I added CalMag plus to my nutes 7 days ago but im not realy getting a response from plant.
Looked at the Complete guide to sick plants and agree it looks like the right Deff.
Im using PBP Bloom, Liquid Karma and CalMag Plus. What do you recommend to solve problem? Im doing a Res change tomorrow anyway. I will be using RO water this change.
My currant nutes are at:
PBP10ML gal
LK10 ml Gal
Cal Mag plus 5Ml Gal

Too much calcium causing potassium def. Your not using enough pbp. Try the following 3 teaspoons (15ml) pbp bloom for hydro + 1 teaspoon (5ml) cal mag plus per gallon (3.8L) of water. Liquid karma is not needed. Raising pbp level also raises your potassium level. You need at least 30 p...you have only 24 with the 10 ml. Raising pbp raises p to 34.

I wouldn't raise ppms any higher than 1500 or u risk burning them. make sure rockwool is flushed. cut your dosage of LK down to 2-5ml per gal and the same with cal/mag. i would keep the ph around 6. your fan is currently blowing directly on plants, this could be causing the plants to transpire to fast which causes the burnt leaves. let the wind from fan bounce of a wall. you may also want to work on lowering temps from hi 70s to low 70s.

keep us posted on what happens

Thanks very much.
Im going with
15ml pbp
5ml CalMag
in RO water
I will see where this puts my ppm and add a bit 2/3 ML of lk if the ppm can take it. I will also adjust my fan as you suggested my RH is a bit low and I havent been doing anf Foiler feedings.


Thanks SunBursT

i use botanicare line of nutes as well im in my 2nd week of flower my ppms are at 1500 right now im gonna up them to 1600-1650 i needed alittle more p and and k a so i bought hydroplex a bloom booster look into it i currently am using pbp bloom, sweet, calmag, silica blast, hydroplex, hydroguard, and some biogenesis synergy almost the same as liquid karma, store was out of the l k so i had to pick up something else its a great product just to much $$$ im doin a rez change 2day so ill post my new formula it works for me in the mean time you can add more pbp bloom for extra potassium but hydroplex is loaded with that k that your plants need goodluck

peace

 

[Playaction]

instead of a bloom booster, i just use pbp for soil... it has added p and k

 

[Guest]

Thanks everyone

I went with
15/ml pbp Bloom
5/ml of cal mag plus
5/ml of LK
this brought my total ppm to 985 using RO water. with a PH of 5.9
I am very happy with the way this looks. I will up the food some depending on what my PPM does after feedings . I want to keep this as simple as I can on this first grow. I like the Lucas formula and would like to use it. It seems to have very good success with other growers. I havent seen a Formula that gives me that using PBP/LK/and calmag plus. But im still reading tons on this every day.
