Can someone please help me out here

[Jesselee33]

I have a hulkberry going into late flowering . I noticed leaf tips yellowing and turning black and some dieing altogether. I have fed a mixture of a bunch of nutrients one time maybe a month ago. I am trying to use as less as possible but if this is happening due to lack of nutrients I would please like someone to tell me which ones are showing if any.

Plant needs food it will use up everything it has stored up just to survive
In flower less N more P K
What soil are they in ?
Light and distance from plant
She looks starved

SHes in Hydrafiber/Soil mix supposed to feed for 4 months. I have a Mars Hydro FC-E 150 and a cheap reddish/purple light off eBay that I use every now and then at the end of light cycles. It is supposed to be 300 Watts but I don't think so because the ppfd is only in the 500 range. Light distance is about 24 inches. She is tied down for better air flow and light penetration

Your soil already was packed with nutrients then you put a mix of stuff in on top
I’m no expert but I would say you probably messed up ph
Let get smart people on this

What do you think ?

I am thinking the 'mixture of a bunch of nutes' a month ago was too much for them (it will take a week to show up if you are in soil) i had a plant last year which was doing great into flower and i added 4ml of PK 14/15 over 2 waterings and it just stopped, locked out and the leaves did the same thing.

Yeah I think that is what is going on . Will flushing with correct PH do anything beneficial?

How long did it take for signs to appear ? It has been well over a month since I did this.

Ok ensure you understand the organic nature of that soil is compromised and after the flush you will need to balance remaining nutrients with what the plant needs. .
This will be tough without lots of experience in plant deficiencies and lockouts.

Should I just harvest early hope for the best and start over before anything major sets in? I somewhat don't like the scent of this strand as it is

 

[JIMKSI64]

Sure you could do that.
Or you could muddle through and use this to learn about growing pot. The issues with lockout and deficiencies will show up in other grows. I would engage full research mode and have charts printed up and taking HD pictures. Start looking at the vein structure on a daily based or at least have those pictures available. A lot of deficiencies look the same but at different times. You will find the major differences start in the veins and the other major clue is top of plant new growth or bottom of the plant old growth. These are key indicators. Also learn the difference between mobile nutrients that the plant can move vrs immobile nutrients that don't move. Get the PH chart for nutrient uptake at what PH range.
Armed with these tools you will be a better grower.

While I do see excess nutrient issues, I believe you should still run this grow out to maturity. For now, use water and water to run-off ... but lets not flush the plants. 10% - 15% run-off should be sufficient

To answer your question about the color changes, some of it is normal as you approach senescence with your grow. The rest of it is your plants have been over-fed. Things don't look horrible though. Keep up the good work and run it out to the end. Next grow, leave out the hydrofiber. It holds moisture too long in soil in my opinion.

I appreciate your input. I'll just let it go and see what happens. Do you think she needs anything at all just water ? And yeah the Hydrafiber does hold water pretty good but I am still able to water once a week

Your plants would benefit from a more complete dry-back. I add 20% perlite to my soil mixes because I want quick dry-back and 3-4 day water cycles.

This is what my soil meter reads if this helps any

The Mars Hydro FC-E 150 is 150W, usually the watts are in the name of the models.

Your PH is very very dangerously low. Get it to 6,5 asap.

24 inches for that light is way too far away for my taste. I would be aiming for 1000+ umols in the middle for mid-late flower, 14" or 16" should be fine, its only a 150W light and I use them too, unless the heat is a problem.

Heat gets up to 93 sometimes with the Mars Hydro on brightest setting. I have a air purifier right next to the plant blowing air under canopy and a big fan blowing at the lights and above canopy

The airflow helps but the high temps aren't ideal. I'm not sure how much control you have over those temps though using a closet as your grow space. Look for ways to lower the daytime temps without compromising the amount of light (if there is a way, you might be stuck with what you have).
