Purple tips in flower from light increase?

[2Bad]

Have a 4x4 with a fce-4800 (480 watts)... had it 50% until week 8 a week ago where I pumped it up to 100% . Week 9 now one of my strains which was a 9 week strain which wasnt thickening up much has now started to thicken a lil but it is showing some purple tips. Maybe 5-6 tiny spots.. The other 3 strains actually look like they are LOVING it. Is it stress? or Genetics? I checked the trichs no amber and I couldnt see cloudy trichs either tbh.

Can anyone help me pls? I also have another plant with some browning on the leaves i havent started flushing yet so idk why its turning brown i attached some pics of it. With is having a ton of new pistils im assuming it still has around another month.

Its my first time in flower i apologize for the newb questions. It said this was a 60 day strain its about day 50 , but it seems like its got 3-4 more weeks.. so instead of late bloom nutrients(synth) should i be doing mid bloom on my feed chart or stick to late bloom?

purpling is normal later in flower under high light intensity if it's in the genetics. no need to worry about that.

the brown spots are calcium lockout due to light intensity. Should've been a bit more gentle with kicking up the light instead of doing an aggressive 50% increase. you should've also had the lights brighter earlier, bit late in the game to be giving em more now. typically you'd be dialing the lights back down by week 8, not turning em up.

my recommendation is bring the lights back a bit. disregard the breeders timing for when they say the strain should be done, that's a useless metric imo. stick with late bloom as there's likely a higher PK ratio that will help the girls bulk up at this point.

I appreciate it man. I messed up alot but i will learn from my mistakes so im not too worried. I will lower the light intensity what do you think? 80-90 percent?

i would drop back to at least 75%, maybe less, and give it a few days. you want to make sure the calcium lockout doesn't progress after bringing the intensity down, then you can start increasing again 5% every other day again.

further, make sure your temps and RH are right. Target should be 82F ambient, 55% RH, 77F - 79F leaf surface. This should get your VPD right and ensure the plants can transpire as effectively as possible which will combat the calcium lockout occurring again and enable the plants to use the higher intensity of light.

Alrighty i appreciate you man. Im in coco by the way incase that infos needed for anything

I have this other plant that looks like some mids(something i wouldnt smoke) and its collapsing over itself, is it worth it to keep? It doesnt seem to be maturing much. Of course i can turn it to wax but will it mold from lying on top of each other. Looks like they have good airflow cus they are in front of the fan

 

[2Bad]

If I grow again i know how many tops to have now. This one has like 25-30 tops

So its coco and i stopped giving microbes a few days ago should i continue it for the deficiency

depends on the kind of nutrients you're using. microbe cultures tend to be pretty self sufficient, and continue to procreate. keep in mind, it's not a deficiency though, it's lockout. deficiency is a lack of something, lockout is the inability for the plant to uptake something caused by another parameter. keep on with your regularly scheduled programming, the root cause was too much light intensity.

Ohh okay I seem to have got that confused my bad lol

The more I got the better answers he can give ya ! Nutes watering habits etc ….

1 thing for sure it helps to bump up those leds gradually not from 50- to 100% give them a minute to adjust more light = more food

Yeah i messed up with the light really bad, I went about it really bad. I learned though always worth it lmfao. Alright heres a bit more info im in Coco with gh trio calmag and azos .. I water once morning once at night .. they vegged about 3-4 months , i have 1 in a 3 gallon pot which is the one with the lockout and then 3 other plants in 1 gallons.

This grow was a great learning experience. I started out in a 4x4 and then after 2 months im like i want to veg more and throw in 3 gallons. But then i just got lazy and vegged and vegged and finally just flipped without even thinking about my lights being at like 30 percent in veg .

 

[tobh]

you could bump up those feed cycles too. twice a day is meh. six times would be wow. coco likes to be wet and how long they vegged means those root systems could take it and run.

I know but its by hand and im not too worried they are doing fine the 3 gallon is getting twice a day and is looking very lovely . Im not planning on automating theres 0$ left in my budget so ill be switching to dry amendments/coco next time for sure. I might even be able to get away watering once a day with the 3 gallon because its got alot of algae on top.

 

[2Bad]

Im ok with little yield this time, i think the 3 gallon will give me a good yield tho. Its thickened up for sure. Ive messed up so many times i cant count on my hands

I agree it’s a useless variable, like it doesn’t say what they grew in what media what nutes lights or grow size or pot size, tf

understandable. it's good though, you seem to be learning from the mistakes. honestly, i would avoid doing dry amendments in coco. it's counterintuitive to all the benefits coco gives you. might as well go to promix instead and still have some of the benefits of coco but the ease of soil. coco runs best when you can run massive volumes of solution through it and get run off consistently. with dry amendments, you'll just be flushing all of your goodies out consistently.

and on the automation front, gotta get on that. hand watering is fine for your first few grows, it really helps you come to understand the plants and gardening overall much better than throwing everything on autopilot. however, after a year or two of hand mixing and hand watering, automation will look mighty appealing. it's not a terribly expensive investment either and in the long run can save you quite a bit of money due to decreased waste.

just some food for thought going forward. you've got things handled well enough at this point for sure, and you will get a reasonable harvest which is a huge win for a new grower regardless if it's seven grams or 700 grams.
