Not sure if this should be in the newbie category, sorry if it is new here... anyways new grower here. Stuck on week 3 right now, trying to correct these deficiencies (or toxicity causing lockout?) before going into flower.

I've ran into the same situation with mine. I also use coco. You're plant looks good tho. I lowered the calmag to only 1ml/g and raised the micro to 7ml/gal. Micro has the same amount of calcium as the calmag does. I supplemented magnesium with a pinch of Epsom salt per gal.

The tight, spindly internodal spacing coming from new growth, dark green outer edges of leaves, purple petriole and stems, and clawing on a few of the bigger fan leaves. Maybe overreacting but just want to be sure before transitioning to flower.

This is exactly what I've been contemplating for that exact reason but being a first timer I thought that could get me in more problems (making my own mix throwing off NER). Most of the issues seem to be near the new growth so I assumed it is an immobile nute problem so maybe I'm lacking some micros?
Edit: and reading up on toxicity/deficiency I thought maybe p is getting locked out from too much calmag?

That's what i chalked it up to. I didn't buff my coco, so i had some yellowing in alot of development early on in its life. From the pictures the plant has already shown sex and start of preflower. Depends on how long you want to run them in veg. Don't know much about photoperiod. Again they look good so far.

I'd try raising the temps a bit, my understanding is that under the new white LEDs you should be running about 82 degrees as the lights don't have the downward heat to raise leaf temps like HID, thus you need warmer temps to get transpiration. Those plants look pretty good, if they are near the size you want em send em. My plants always take off in flower and I've sent some looking worse than those.

I don't understand your ec readings ec is usually like .5 or 1 or 1.5 ect. Are your readings in ppm?

I have had this before. Just get more run off and it goes. Also check your ph tester is bang on.

1500ec? you mean 1500ppm? pretty hot for a small pot soil grow. 1 gallon won't be enough space in my opinion. too little soil, too much fert, but looks good so far, oddly enough.

Thanks for the advice. Read up on it and decided to increase my temps to 80-82°f. I meant to say 1.5ec. You think I should keep increasing ec if I don't see burn or those seem like a ok numbers to stick at?

No. Don't keep adding fertilizer until the plants start overdosing. Add fertilizer when the plants tell you they need it (if deficiencies begin to show themselves).

1.5 EC = 1050 PPM

That seems high to me already. I rarely am outside of the 750-850 range. I don't recall having to go above 900 for any of my plants. Not saying that's for everyone by any means, but it's been consistent for me.

Honestly can't answer the veg ppm question, I've been struggling with vegging plants longer and prob need to up my feed some. I was used to just vegging for a short while then flipping. Since I moved I need to grow bigger plants and have a bad habit of underfeeding during veg. Those plants look better than the ones I sent to flower last run and they are killing it. My plants always seem to take off as soon as I flip to flower. I used to just think plants liked the longer dark period but lately have started thinking I've been underfeeding during late veg for years now.

If you are watering everyday I think you might be on the verge of waterboarding them.

Bigger drinks and let the plant suck up that water and dry it out a bit and then big drink again.

Based on the little bit fatter edge to the leaf and your saying you water every day. Also the top of the plant twisting slightly because overwatering looks like anything and everything.

I let the pots get practically dry. I water 3x a day rn because the pots are so small, was actually thinking I might be under watering because of how fast they're drinkin. Doesn't help that half the stuff I read says let coco go through wet/dry cycles and the other half says it should be 80-90% saturated at all times smh

Oh, I didn't realize how small those pots were, you might need to pot up. I really mostly know outdoor plants, and suck at indoor, but that looked a bit like water stress, but might be root bound? I am not sure, but yeah the solo cup under the pot I missed.
