I seen on other post that Fastbuds seeds take well to topping. I was shocked that it took only about 1-1.5 days for both plants recover and continue growing. Both are about day 16 in said picture so i started tying down the top 2 sites so the lower 2 can catch up.
A bit scared if #1 is showing nutrient burn, or just growing since some strains leaves do change color. #2 is a bit smaller but looking healthy and loving everything
Looks like one of the plants got nute burn. Looks like I am going to have to wait to give #1 more dry amendments in 2 weeks. Overall both are showing growth each day and stretching out their new branches.
Have not feed both plants since a few weeks ago and still may push it off instead of doing it next week. They both are showing N toxicity and curling.
Still stretching the main branches out to the side giving a wonderful canopy.
Still a bit disappointed in myself for my first dry amendment grow. I checked what I gave them and they should be happy, but they are both showing slow growth from nutriant burn
I should be giving both of them their final dry amendment feeding for the rest of the grow this week, but I want to push it off. Both plants from what I can tell are getting nutrient burn from Nitrogen ( dark green leaves) and unsure if I should just flush or not.
I wouldn't feed anymore. Maybe reformulate a bit because something is out of balance in nutrient diet.
These plants might be a bit overfed on N - dark/glossy - but the other symptoms are not n-tox related. Maybe too much P, too little K or nute-lockout of some sort (mulder's chart). Knowing the proportions of how you feed would help out greatly to deduce what it is. It's muc more difficult measuring waht you add over time compared to a soilless/hydro context, but it all should be in similar ratios.
Weighted average of npk, if using "organic" N sourceces, 2-1-2, and with readily available N sources 1-1-2 is good ballpark to start -- these are rough ideas. Some sources of N require bacteria and other stuff to help break it down, so you need a healthy stock of inputs for the right amount of plant-available N on the output side. if you find .7-1.2-2.3 works over several months without issues after adjusting from 1-1-2, then that's what works. Observation and adjustments requried. It'd be some sort of whacky ratio of whole numbers, so take these rounded suggestions as a grain of salt. If your current ratio relative eto dosage is way off, consider adjusting it... also it might point toward a diagnosis too.
I like the water-only idea for a bit. Let those leaves cannibalize themselves a bit. See how the 'other' damage progresses to help identify it.
Flushing is for extreme catastrophe, and i don't think you are at that point. Minimal runoff in soil or 10% in soiless as normal is fine.
That damage is not N-related. it is at the top of the plant. N can lockout potassium, but your plant doesn't seem sickly enough for that to be the case. could be wrong. Too much p is something often recommended for flower. usually it is a total waste to add more.
Research backs that up and my own experience does as well. I've been playing with elevated P levels from 50-70ppm for the last couple years and don't see a reason to continue to do so. 40-50ppm is fine in a soilless fertigation regimen seed to harvest. In facts multiple studies have shownmore than 30ppm is not adding anything to the plant either - yield or potency. Numerous studies show that amping up pa nd k in flower do not bulk up yields. this is just another false anecdote of people that want to beleive what they do always has a positive effect without ever measuring and comparing to a control group. though i'll still stay around 40-60ppm due to OCD and not anything intelligent, lol.
So I overcalculated my amount of dry amendments and instead of calculating 5gal pots I did it for 7gal. With that I can still see what the nitrogen toxicity is still lingering, but slowly letting go. Both are fattening up, but I can see plant #2 genetics are strong. Even with nitrogen tox her flower sites are coming in a beautiful hue of purple.
I may just let them ride the rest out and let them eat the rest of the leaves instead of giving her any more nutes.
Both plants are fattening up well, went in and moved some of the colas to help increase air flow. Plant #2 is getting purple as all getup and I am loving how she looks.
starting to look at the tricomes on #1. There is a bit of amber on the leaf tips, sow now I am waiting for the flower itself to get a bit amber. She is still trying to fatten up on some branches.
plant #2 is still getting fetter on all of her branches. It looks like the nutes were not as hard on her as her sister.
