so these are dynamites which i was told is a slightly heavy feeder which i didnt up my nutes at all ive been giving them the same thing the since like my 3rd grow everything else is healthy with a very slight tip burn on a few of my plants

now when i did a flush ont he dynamits no color came outa the water so i renuted now aftera few days it got worse so i thought maby there low on nutes so i have them somemore pbp and hydroplex now i think butam not sure they stoped burning but i dunno

now some of the other plants leaves that were inthe direct footprint of my light are turning yellow but no crisping which i assume is light bleaching which i thought the dynamites had till they started crisping

now i got 12 dynamites im aboutto put into flower in 2 weeks and i really want to figure this out b4 i run into more problems

jillybean for comparison next plant over

i lowered the plant (the plant is reallyshort so it was up on somthing then i raised my lights all the way up and lwered the plant itself but it just kept burning and burning
it stoped i think whne i gave it more pbp and hydroplex but it was so bad i really cant tell anymore

all the other plants right by the dynimite have slight bleaching probs n a few leaves maby the cynamite is just a light sensitive plant?

my 600ws are air cooled and no it wasnt really hot under the light but i know thats where this problem started all teh other plants at the same level are not burnt onlythe fan leaves that are higher up on the colas on my wonderfuck are turning yellow but not burnt

That one has phosphorus def, you can see the dark dull grey/green splotches on lower leaves, and that tip burning is severe phos def.

What are you feeding for bloom?

 

[Dr. G]

1-1.5 tbs per gal of pbp
10 ml lk
10-15 ml sweet
5 ml of hydroplex
sometimes hygrozyme
5 ml siica blast
5 ml calmg

my other plants love thismix maby i shold up it for my next run? or do youthink it was locked out

my runoff was at 6.65 and the ppms were 500

where's the fucking pics??????

 

[Dr. G]

you cant see any? i9 can see all but one

i tried to upload them to my gallery but it took forever then did nothing after the bar was full ill try again

Is that PBP bloom? You need to increase that dosage as the plant progresses, especially after week 4. Also you must take into account that you are providing 1200 watts of light, therefore plant metabolism is raised, nute requirements go up. Nevermind what the other strains like, they are all different. They could all use a boost of bloom, judging by the lack of any tip burn on the good plants. Yield could be affected.

PH should come down a bit, as well. Runoff should be around 6.2.

PPMs are way low, but you need to measure ppm of ferts before watering:

This is from the Botanicare site.

Seedlings 500 ppm
Mid Size 900 ppm
Mature 1300 ppm
Fruiting/Flowering 1500 ppm
Aggressive 1800 ppm
Super Aggressive 2400 ppm

Pure Blend Pro Bloom (2.5-2-5). P value of 2 isn't very high, so you must increase bloom dose. They recommend 15- 30 ml / L of water, you are feeding about 1 ml/L. I would increase to 15ml/ L and observe. Keep in mind organic nutes need a week or so to break down and become available to the plant, always keep this delay in mind when feeding and observing results. I use BioBizz and the NPK of the bloom is 2-6-3.5 and I feed 4 ml/L at the heaviest phase of flowering.

ya but i supplement with hydroplex thats why i dont up the pbp bloom i start hydro plex on the "water" cycle about week3-4 so these dynamites need alot more p? thats whati thought at first but usually i have a over nute problem and this is my first time running dynamite thanks alot for your help everyone who helped sorry bout the pics
