Leaves drooping, yellow specks on 2 fan leaves?

What is my plant trying to tell me? Lights have been on now for 6 hours. I'm feeding it foxfarm trio + open sesame according to feed chart. With just water every 3rd feeding. Watering it every 2 days, that's when the moisture probe shows it being "dry" ish. Temp is around 82f with lights on, 50-55% RH. 75f/50-55% lights off. 2 of the leaves have tiny yellow specks on it and the stem is getting a purple streak?

Not sure how much help I can be but what medium are you growing in?

I'm using foxfarm happyfrog potting soil. I think I may have figured it out though. Just checked the run off now. 1550ppm on run off. That's too high right?

Ok soil, was going to say they could be overfed. So you say you feed, feed, water?

Most I've done with ff trio is water, feed, water... at 50-75% strength and still had overfeeding issues. Maybe skip a couple feeds and plain water with plenty of runoff to rinse some of the salts out. Then resume feeding every other or third watering.

Are you going full strength with what the chart says? I also have no experience with their bloom boosters.

Your environment seems ok, what kind of light are you using?

Okay, so I ended up flushing all 3 plants down to 950-1000ppm. they were all around 1550-1650ppm on run off.

Yes I was feed, feed, watering. Going off foxfarms feed schedule at full strength (week 5 on feed schedule)

According to FF soil feed chart for week 5

Grow big - 10ml
Big bloom - 15ml
Tiger bloom - 10ml
Open sesame - 1/4tsp
Cal-mag 3ml (forgot about this one, not included on their schedule)

I'll try watering for the next 2 feeds, then drop the nutes down 50%. Feed, water, water, feed @ 50% dose.

My light is a Mars hydro TSW2000 300watt led board.

Ok good try that, I think foxfarm recommends a little too much. Someone else might have better advice though.

Also make sure you're letting the pots dry enough. The plants have a droop to them and I'm not sure if it's overwatering or something else.

Overwatered.. Try every 3 days instead of every 2..

Update - they are looking happy again after flushing 3 times with ph'd water.

Stop using calmag

can you explain to me why? im still learning but I've heard some folks say plants grown under LED lights need Cal-Mag during the flowering stage, but I don't know that for a fact.

I believe he is thinking you have a Calcium toxicity from the closeup picture on the leaf that has brown spots. That's also what I tought looked similar too so definitely check out the website Grow weed easy to diagnose the plant yourself aswell, its true that led requires more but there must be a limit, How much are you feeding calmag/gallon? I use 5ml and so far no problems but have been growing for a just a month.

Yea, cause you don't need it.
#1 overused product.
There are instances when someone needs to use Calmag but not here.

Okay, no more cal-mag.

I'll check out the website. I've only been putting in 3ml to my gallon jugs of water. I'll cut it out from the feedings. Plant already looking way better (minus the one that stretched like crazy, my fault on that....) now that I've only been feeding it water. Run off came out to be 650ish ppm. I think I'll try 1/4th or 1/2 dose according to foxfarm nutes.

After these are done I'm just going to switch to full organic. Foxfarm HF + Gaia green or dr.earth. Seems like it's easier to feed that way, dont have to keep mixing up nutes every week a and harder to mess up.

I tried ffof and dr. earth with my plants last year and it turned out alright. Just don't top dress too late, I made that mistake toward the end.
Still easier than mixing nutrients for me though, feel like the bottled stuff is better suited to soilless mediums where you have more control.

Your plants look alot better, hope they stay on track. I would try 50% on the nutes since you're reducing feed frequency as well, dont want to underfeed lol, but that's just a guess.
Probably for the best to cut out the calmag. It's better at treating deficiencies instead of preventing them from what I've read, and some has nitrogen which can be bad for flower.

Also read a little about open sesame, it's really concentrated and should only be fed once a week. Wasn't sure how often you were using it, but something to look into.

Yea I was contemplating the open sesame. I've only used it once on that last feeding that hurt Mr stretch. On the next feeding I'll try 50% for the trio. And instead of 1/4 tsp (like the feed chart suggest when mixed with other nutes) I'll try 1/8 tsp instead. See how it responds. If nothing bad happens I'll just feed 1/8tsp once a week.

Out of curiosity. Howlong does the organic stuff take to breakdown and actually begin to benefit the plant? I figured happy frog should keep an auto flower (starting from seed) fed for atleast 3 or 4 weeks. Do you top feed at 3 or 4 weeks? Or do you do it sooner to give it time to break down into plant food?

I've read it takes a week or two for the amendments to break down(I use dr. Earth), and the ocean forest seems to tap out at 3 weeks for me, so I top dress at two weeks.
But I transplanted twice, both times at 3 weeks, so no need to top dress there until they're in the final pots.
I also water with recharge once a week and put a layer of earthworm castings and fresh soil at 50/50 on top when I amend. They add microbes that break it down much faster.

Not sure how that translates to happy frog. I hear it's lighter than ffof so you'll have to feel out yourself when to amend but two weeks works for me.

Hope that helps. Check out the organics section, there's alot of good info there as well as a couple threads dedicated to dr. Earth and Gaia green.

What are you using to feed waterwise? tap or Ro or a combo of the 2? If you are using RO you absolutely do not want to skip calmag and you should actually only use the organic calmag that is derived from cacium carbonate and other carbonates, those are importante for ph fluctuations, After my talk with dr. smith I am positive that @Jjgrow420 is watering with tap water or a combo of tap and ro. I know this because I was using only ro water but my ph keeps dropping and it is because there is not enough carbonates to buffer the solution and stabilize it so if he was growing under led using ro water and not using calmag I bet he would have had something to figure out long ago to keep growing successfully. If you really care about it like I do you should go to your city water distric website and look at the water analysis, for example in my water there are already 75ppm of calcium and 25ppm of magnesium and that equates more or less to 0.7ml per gallon of calmag, so now instead of 3ml of calmag I feed 2 because almost one is already in the water, and you wanna start with water that has about 0.3 ec or 150ppm and you should achieve this numbers balancing tap and ro and add nutes to that water combo.
Its a real thing those elements are some of the most present in all waters so it makes sense that if you using tap water you could potentially never encounter calmag issues.
Hope this helps.
Helped me a lot for sure
