Help please. Going downhill fast

You cannot mix silica and calcium together at strength. Always mix silica in the water first and give 15 - 30 minutes to bond to the water add the mega crop and then the calcium then beneficials. Too much free silica can wrap it self around the calcium slowing down the calcium uptake

Your well water is a big wild card it could be all Mg? or just really soft water. It makes a difference in your nutrient ratios.

It looks like a calcium problem but I don't think the problem is stemming from the amount of calcium present but more an inability to absorb it.

When was the last time you calibrated your PH meter? When was the last time you did a flush?

I would do a good top flush followed by 2.5gMC, 1g Epsom Salt and .5 g calmag/gallon & Kelp, Humic Acid and B-Vitamins

So flush with plain water and add the MC, epsom, calmag, kelp, humic and B1 to the res? Any amount for the help, humic and B1, or just what the bag says?

I flush every weekend with recharge. Calibrate pH meter start of every run, so that was calibrated like 45 days ago. Apera pH pen. Usually mix calmag 1st, then silica, then megacrop, let it sit for a day, pH, sit for another day, adjust pH then into the res where it goes through about a gallon a day at the moment

Wow I hit the nail on the head with this one ............... Cal-mag first then Silica makes the calcium less available to the plant. The silica literally coats the calcium in a shell of ions. So even though you are putting plenty in the nutrient mix the plant cannot use it fast enough.

You are in coco and perlite right? Flush with 5.8 PH Water plus 50 PPM cal-mag. Then right away feed with the mix I posted. Yes just add beneficials at the rate from the vendors. Don't use recharge as a flush but as a beneficial. It is wise to feed at a lower rate for a day or two after using recharge.

Awesome. I appreciate the help. Have to order some of those things so I'll update later in the week. I don't necessarily flush with recharge but I use 1/4 strength feed plus recharge and run a half gallon through the top of the pots weekly

Update with new pictures! These pictures are from today. Plants have stretched a good 6-8in since last pics. Haven't changed a thing yet. Still same feed in the res. New growth looking much better for some reason... Bennies came in the mail today. Cleaned res and autopots. Flushed with 3 gallons of 5.8 with only 50ppm calmag per gallon, per plant, and mixed a fresh batch of megacrop, epsom salt, TPS calmag, with humic, kelp and b1 according to labels per MOG suggestion and put that in the res. Mix of everything in recipe totals 595ppm including tap water

Update. Think I might still have some issues. The one I snapped in half is stretching now so that's cool. Tops and new growth looking pretty good but lots of bottom leaves yellowing and falling off. Picking them daily now. Seems much quicker then if it was from light. Especially since the worst is the one that's spread out the most. Followed M.O.G directions to a tee and recalibrated pH meter. 2.5g megacrop, 1g epsom, 0.5ml calmag, 0.65 humic, 0.25 kelp, 0.45 b1. 5.8-6.1 all week. Only thing I can think of is my calmag is 0-0-0 and 30ppm. So maybe more megacrop or more calmag?

Those are mephisto in the back; samsquatch x forum stomper on the left and toofless alien on the right. And rocbud blueberry slushy that was busted front left and rocbud smackz front right. In case anybody is interested in how each is dealing with the stress. No balls yet but checking the front 2 regularly

if new growth looks good stay on course.. damaged leaves may get cannibalized

Latest update. Well into flower now around 60 days old. The 2 bigger plants in the back are pretty light green. 2 in the front color looks pretty good. All 4 plants have all purple stems and the back right the leaves are going purple, and I don't think that's supposed to be a purple plant. Still feeding 2.5g MC, 1g epsom, 30ppm calmag, humic, kelp, b1 middle of range per bag instructions

As they continue to struggle down the homestretch i figured I'd give a glamour shot to show that the plants can take a beating and you can still get by with a little help from friends... Thanks M.O.G.! for setting me on a path that taught me things, helped me narrow it down to an equipment malfunction, and gives me more hope with the megacrop/autopot combo. Front right plant in the pictures, Rocbud Smackz at 70 days. Chop maybe next weekend...
