You can also flush out the excess nutrients pretty easy. Just keep pouring your nutrient solution untill the in and out numbers match. Or just feed lighter and later.
I would think this is generally legit?
"I would like to offer a ppm chart as a rule of thumb or ball park target ppm, but each grow or garden is going to be different.
These numbers are based on EC readings, .500 readings, TDS readings converted from EC or the common Hannah Chart:
Seedlings, Early Sprouts 100 to 250
Early Vegging 300 to 400
Full Vegetation 450 to 700
Early Blooming 750 to 950
Full Mature Blooms 1000 to 1600
(this excludes the ppm of your water)"
Also the ec of the water needs to be included with the total ec because if the nutrient solution is say 1.4 ec and the water is .4 ec you are giving the plant a 1.8 (900ppm) solution and it may be too much.
I thought you were supposed to subtract the water ppm from the final count.
From the Dyna Grow feed chart:
PPM (Parts-Per-Million)Our PPM values are based on elemental weights and percentages and should be used as an estimate. Staying within a range of 150± would be optimum. If using water other than Reverse Osmosis, obtain the ppm before adding your nutrients and supplements, then subtract that amount from your total.
I'm new to led and trying to dial things in. 100w hlg plants are getting 800 now and the tips barely burn. Next feed straight water.Ok the low end is a good guide except sensitive plants will likely want to stay under 1.5ec 750 ppm at peak bloom.

So always err on the side of underfeeding. Can always give more easier than take away.
Also another tip. Before led i read a tip that the max directions on a weed nute bottle are for 1000w hps. So if running a 600w hps shoot for 60% of max directions.
Not sure how that converts to todays led lamps and fuller spectrums bit it is a good guideline that tends to hold true. I am usually at 60% of directions on average at peak bloom.
As a guide. Still have to read the plants of course.

A little tip burn isn't gonna hurt at all. I just use plain water and next feed will be 750. I'm thinking about going to promix or straight hydro. It's real tricky trying to mix organic and bottles.Ok. But barely burning means you are already too hot. Once we see a deficiency or problem it likely started last week before we see it.
I say it a lot but i live and grow by it.
Alway err on the side of underfeeding. :-)

Watered the back row today got one very high run off read & two closer to reasonable.
LSD #2 PH 6.3 PPM 566
LSD #4 PH 6.4 PPM 387
Gelato #2 PH 6.3 PPM 375

Re-potting to these over next weekend.The one big disadvantage I found with those pots, and I love terracotta, is there is only one drainage hole in the middle of the pot, if this blocks you'll have problems you wont be able to diagnose. The really big ones work better, but the weight of them is unreal when it comes to moving them.

Nah, that's mosquito bits, I let them dry out plenty, watering about every 3-4 days as needed, someone mentioned over at GrowDiaries that my pH might be too high, its been running 6.5/6.6 in run off so I think this might be factoring in.Look watered too often. You can see the perlite is staying tan. Always a sign its staying wet too long.
I would be using 2.5 ml foliage pro a week or so on that size plant so you should be fed.
Let them dry out real light and i bet they perk back up. The roots are drowned some at this point.
Thats my guess.

I haven't been flushing straight water but have been watering to run off after dry since I started feeding (was shy to do this when seedlings not wanting to waterlog with BX) & got those original high ppm #s. Most have dropped to about 100 ppm (or less as low as 30) above of the solution all but that blotchy LSD #1 & Gelato #2 look a bit N starved to me + Gelato #1 which has already been topped has been taking off, been tempted to up from 2 to 3 ml.I looked again. I see the mosquito bits. Lol
I wouldnt think a few 10ths of a point of ph would do that. But i do see the ph looking stripes and leaf kink. They look like water stressed still to me. Did you flush them I forget sorry. Cause that can cause temporary throw off the ph at the root zone. You would need a good slurry test to confirm.
If they have not been too wet i would try increasing feed strength a little and see. Because if the ph is high like they said that shows the plants have eaten all the nutes. They may be hungry?
Hope this helps.
