So I grow indoors in 6- 4'x5' beds, 6000watts of HPS lights in soil. 77-80 degrees 60% Humidity lights out, 87-91ish 40-50% lights on. Dynagrow nutes with some amendments in soil (bat guano, seabird guano, bloodmeal, bonemeal, epsom salts worm castings, dolomite )and a 20-20-20 boost 1st half of flower and 0-50-30 boost 2nd half. This is a tried and true blend and has been used for 20 years by other friends of mine and by me for a year now. Presently growing Chemoto Dragon, Strawberry Romulan and Lavender voodoo.

Watered in 1st half of grow nutes at around .5-.8 EC ph 6-6.5 (maybe a little lighter on nutes than usual) Stretch ended a week or so ago, Presently in week 6, of 10ish, using the later stage nutes now for flowers with more P and K. Never watered in nutes higher than 1.4 EC in the can (I have a 55gal drum with pump into PVC watering system)

After taking soil samples...EC readings are between 1.3-2.3 so a bit high on 2 of the beds with the 2.3 but pretty well "in the zone" for others Ph is lowish 5.6. This is NOT runoff but samples from all beds of soil. Would love some good opinions on what is going on here?? I have done MUCH research, been growing on my own a year or so, and have come up with several diagnoses. Not going to offer them all in speculation as to not sway anyone any particular way I WILL say I think I have a little bug issue with those yellow spotted leaves and have noticed what may be spider mites, underneath, of which I have never had issues with before. BUT, the other leaves are certainly something else and the same leaf damage from the mites at present, is not occurring in the other beds...that I have seen.

The 123616 pic is my bed of Lavender, it seems pretty stunted, although I understand it stays short and bushy typically, but this seems a bit much. The buds are solid and of decent size though. Pic 3227 is one of my beds of Chemoto Dragon Although I trained these plants a bit different this time it seems to me that the Chemoto did not stretch as much this time. Again the buds seem to be forming up fine and hope to see more weight amass in the next few weeks on some of the non-main stem colas. Thanks in advance to any and all who read and chime in. Tried to be detailed as to give full picture and not have to go back and forth 10 times with questions. Any other info needed please ask.

Sorry all...I ended up posting it would seem without full content. I'd gotten pulled away by my son who needed a ride and I did not realize my draft got posted. I DID CAL MAG all beds yesterday in a pretty good watering.

Appreciate info. Is that the yellowing on outside edges AND the 3 leaves that have the browning/yellowing, dying going on?
Those plants look to have been fed more than enough of everything. My "needs calmag" comment was made prior to you posting the pictures and I was being sarcastic as that's a standard generic post made by many thinking it's a cure all. In your case I would not add anything. Too much calcium can lock out other nutrients. It's obvious that you have some deficiencies but it's not from underfeeding it's from overfeeding.

Heard, I kinda thought you were being sarcastic seeing the time you posted and what others were saying about my mistaken post. I put only 1/4 the recommended amount of Cal Mag when I watered yesterday, no other nutrients added. The overfeeding would go along with the leaves being somewhat brittle as well, I guess. I only added the Cal Mag because of the not so high EC readings. Weird as the strength of my mix was never all that high as well as the recent soil samples I took not being overly overboard. I'll try more samples and get some runoff next watering.

I'm not a pro at this, but don't use calmag in soil. The dg nutes have absolutely everything you need.
Your soil prob has everything as well, try just plain water at like 6.5 - 7 ish ph. Water when the soil is pretty dry, like 1 inch down dry on top.
All nutrients have to be present in somewhat close to the right levels for any of it to be used, ph needs to be in range as well. Thays why feeding stuff all by itself might not work like you would think. In soil though it takes longer to change.

This is regurgitated info form this site :)

I am actually thinking about running one big bag of dirt like that in my tent. Idk, this grow I'm using pots because I already started. Do you like it or is it something you wont do again?

Your plant looks like it will be fine imo.

I'm with @xtsho it looks like you are locked out.

I see a little bit of K (potassium) deficiency on one plant that's the only deficiency I see. Those yellowing and brown spots can happen to leaves when they are touching the dirt and get watered. That can also happen when a fan leaf is at the bottom of a plant and isn't getting enough light penetration. I trim enough to make sure none of the leaves are touching the substrate. I also see a lot of N (Nitrogen) in your leaves. So I'd do exactly what xtsho suggested. I agree with @Roy O'Bannon you should be fine.

I like the beds pretty well, it beats hauling pots around and its nice to have the extra room for roots, watering is easy with auto system or by hand if need be. Biggest maybe only drawback I've sort of experienced is dealing with plant/soil issues as you need to basically treat the whole bed. I do not really flush so much per se at the end, as it takes a huge amount of water to do so, but just feed with water only last 7-12 days. I am sort of committed to them at this point but am looking to set up a 5x5 tent in another room within the next month or so.

Yes I am going to back off nutes and feed water for now

Thanks curious...yes I usually trim up a few inches from soil did something a bit different this time (not sure if I'll like it or not yield- wise). Indeed too many leaves are too close to soil and I am NOT liking THAT. So I guess I'll just feed with water and hope to free everything up for a week or 2? Just weird as I thought I was actually BELOW my normal regiment, watered with only water several waterings in first half and in between stages for a few days the soil measurements were right in range (i'll check again with runoff from beds). Always appreciative of a learned point of view.
