Does anyone know what this is?

[kroniq time]

Hi everyone how is all im having a little bit of a concern involving one of my ladies to be precise my Barneys Farm Vanilla Kush she is growing in soil containing slow release and blood and bone feeding soluble bloom booster once a week and the off week is tap water that i let sitting for a week. My ladies are under 2 x 400w mars ii led lights they have had a total of 8 wks vege and are now into their 3 wk flower

pls any help will be appreciated as i am a bit worried this could affect her and cause her to not fill out and mature being my first indoor grow i have been exceptionally pleased that i had not sustained any problems until now Ha there goes my perfect first indoor grow without problems out the window now.
I do have a theory on the matter but just to be sure I'll wait for some feedback first before applying any methods so peace out and happy growing to all

More information is needed. This could be a deficiency, or PH lockout. Where is this problem appearing on the plant? Top? Bottom?

This may be your problem -

she is growing in soil containing slow release and blood and bone

Even when you only give her water without bloom booster, she is still getting dissolved slow release nutes, so she's getting fertilized all the time.

 

[GrizzWald]

Calcium be my bet. Cal/mag and p/h adjust your water.

 

[Stealthboat]

1. Check that soil ph, adjust if needed (ph of soil grows should be around 6.2-7).
2. Slow up on the nutes since you're using the time release soil.
3. Do you know the specs of your tap water? PPM, ph, stuff like that.
4. Fill out that chart Antics suggested and we will solve this thing man

Those seem like some strong nutes, makes me think over-fertilizing is happening. Temps are ok but could stand to be a few degrees lower. Do you know your humidity levels? You also say you water every 3 or 4 days. I don't have experience with soil but that seems like a little too much water IMO, do you use the lift-the-pot method or just water on a straight schedule of 3/4 days?

 

[kroniq time]

Straight schedule for watering dont know my humidity levels but i do believe i have feed her a bit strongly will counter with straight water next 4 feeds still it baffles me a little bit i have five plants in total different strains bar 2 running same schedule but only my VK seems to be stressing did notice she is also the only plant in a different pot to the others drainage might not be as efficient could this be a contributing factor aswell?

 

[Stealthboat]

Yeah the drainage might be a factor, a great substance to add to soil making it more airy is perlite. My soilless medium is 30-40% perlite.

and these photos were taken on their 21st day of flowering

well sounds like u have the answers already In this thread. time release are a B**** to control. straight water for a while. is this wk 3 from switching the lights or from sexing. cause I woldnt have thought they were that far along. I hope this gets better for you. would love to see a review for this strain. good luck

 

[kroniq time]

I have to agree with you there self inflicted i'd say i didnt weigh up my adds to the mix all done by eye and hand a slight error on my behalf when rushed to setup. My next mixes will be more carefully calculated and its been 21 days from switching lights to 12/12 schedule and yes I would love also to write a review on this strain kust hope i can fix her before she ends

 

[Blueballavngr]

everyone counts it differently, theres no correct way really. usually around wk 3 from sexing or 4.5 from light switch is when I start to see deficiencies and that's in a hot soil in 15 gal pots. but all mixes are different so it may not be the same for you. those time release might carry you a while, unfortunately its gonna be a guessing game for a while. some people are against it but I use foliar sprays in early flower, and seaweed extract is great for stressed plants. I use about a tbsp per quart. my girls have been pretty forgiving to mistakes with the use of it. it also produces more bud sites when used appropriately. well best of luck
