Early flower, need help asap

I have a cannabis plant in coco coir. Feed ec has been 1450 to 1550 and run off ec has been consistently low for about a week at 1250. My plant is in week 3 of flowering. I supplement with 3.75ml/gal of calmag and ensure my feed ec has a ph between 5.8 and 6.2. Now my plant is showing odd coloring and leaf tip burn. Looks like pale interveinal coloring and brown/white tips on new growth only.

I've performed a light flush just in case.

My hunch is either to increase feed ec, increase calmag to full dose or both

Thanks for any help!

Your plants don't look bad at all.
I never go over 1.2 EC and never have an issue.
I never use a calmag supplement........I use tap water.
I also never check the EC of the run off or the pH.
What is your feeding schedule?
Do you ever use plain water?
I don't understand the early flower in your thread title.
 
Id raise ec little by little until it looks good and/or runoff ec being up to .3 higher than inflow. Could be too much light, how much ppfd you think? I never used calmag only when I first started it caused lockout so I removed it but sometimes you have to add it. Id add cautiously.

What nute brand is it? Tap or ro? I had to go from 1.1ec to 1.7 with .5ec being tap so its possible. People have implied its impossible for runoff to be lower than input but Ive seen it by a small amount but not as much as you say. Its for sure a sign to me to go up.

How many times per day fed? Auto drip or hand feed?

My light is about 12 to 13 inches away, mars hydro ts1000, thats the recommended height for flower. But I could move it back a little

I've veen using GH Flora with tap water. I feed 5x per day with an automatic system with a halo. I usually do a flush ever week or two

I use GH Flora Series as well with tap water. 5 ml micro and 10 ml bloom per gallon........no calmag and no issues.
Why do you flush and do you flush with plain water?

Well I generally go by the recommendations of the cocoforcannabis site. They say to always use calmag with coco. And the recommend periodic flushes
 
I started out listening to that site its good it covers all angles of things but then got issues. Some dont but I had to come here and slowly get sucked into the forum lol. To not use calmag amd few other things Ive learned outside of that site.

Not much to learn with dtw coco its why I like it, someone as slow as me can do it. So dont be affraid to play around see what might not be necissary. I use maxibloom one part its sooo much easier. My plants dont need a change in nutrient element ratio from week to week.

I do same ec all the way to end same everything.
 
People dont usually get calmag issues these days, I heard here the quality has gone up a lot in last ten years. I still rinse and buffer my coco just so I can confidently rule that out. Never plain water unless your flushing properly if thats your thing. That hydro nutes typically accomedate for drain to waste coco at that.

I wouldnt listen to a robot, I did recently and had a headache. In short, take ai as a grain of salt, it was right here and there but mislead me more. It can give you conflicting answers. The best answers come with experience and learning from others at places like this. Even we are wrong sometimes.
 
I was using ts1000 max power but yes 18-24” but only to even the ppfd output. Ive had them close. Theyre not that strong of lights to cause your issue. My best growth has been under a ts1000. My vipar spectra ks3000 is a strong light that caused issues, only had it at 50% for rest of run. This run I got it up to 75%.

5x a day is a good amount to feed per day, Ive fed 8x a day to 4x same ec to see it get less food. From overfed to ok. Just watch for runoff being really high if you start getting burns which I just increase runoff and add an extra feed a day. Till it is within .3 ec from inflow.

Otherwise I wouldnt change anything. The deeper you dig the more youll see people actually do check runoff ec and even runoff ph. I almost went that far but everythings good so why bother.

Im betting it just needs more ec like deep seek said but beware ai can be wrong. Giving me hvac advice that a qualified hvac guy disagreed with and was right.

Maybe you use hard tap water? I've always seen that calmag is a requirement for coco and that typically calcium and magnesium are the most common issues. I'll let you know how it goes

My tap water is around 200 ppm. Obviously there's a problem with the chart you're following because you started this thread due to developing issues with your plants. You ask for help, yet rather than take it you question it.
Good luck to you!
