Too late to save?

I’ve had fourteen grows, some bad, mostly good though. But this one has me stumped. It’s two sativa-dominant hybrid grown from healthy clones (details below).

I tried every approach imaginable and after nothing improved them, I re-examined my soil stash and concluded that it’s lost structure and is probably the problem.

Yesterday I transplanted them and used a new bag of Ocean Forest. I’m concerned that there aren’t enough healthy leaves to get to the finish but wondered if anyone has any suggestions on what to do.


Week 4 of flowering.

tent is 75 degrees 65% rh

12/12 light schedule

Spyder sf 2000 led 200 watt

Lumens - 70,000

Fox farms ocean forest soil, five gallon fabric pot

Alkaline spring water with high ph and low tds.

Watering/feeding at ph 6.3 and using one tsp liquid calmag with feedings along with Fox Farm’s recommended nutes by week, at 1/2 their recommended dose.IMG_2476.jpeg
 
Root cause (pun intended)
I’d be comfortable saying it’s in your root zone. Unless you’re feeding an inert medium than you don’t have enough biology in that wee fabric pot for sustainable growth without throwing something out of wack.
Honestly I’d give it a good top dress with some EWC, FFOF, and definitely skip the cal mag.

…My apologies I just noticed I missed where wrote you transplanted. So disregard top dress lol.

I’d say you have done all u can to try and limp it along if u need the bud but shes losing most of that foliage. But going forward if your using FFOF if you just lightly top dress with that much more frequently (every-every other water you’ll see better results)

I'm going with this...that pot is too small for that plant, which will cause nute problems in itself.

Nah, there's no way that plant pot is too small for that plant, I've seen plants 3 times the size of that plant in smaller pots and they were perfectly healthy. Those yellow leaves indicate that he has a nitrogen deficiency that is in the late stages of the deficiency. It's a nutrient deficiency. Plants don't just go yellow like that because the plant pot is too small. You need to learn to read what the plant is telling you. A nitrogen deficiency will always start at the bottom of the plant and work it's way up to the top of the plant. That's how you can tell the deficiency is in it's late stages. He either isn't feeding the plant enough nitrogen or he has a nitrogen lockout which could be caused by adding too much calcium and magnesium (cal-mag). He mentioned that he is using fox farms at 1/2 strength which already has calcium and magnesium in the feed. So adding cal-mag along with the fox farms nutrients means he probably has a nitrogen lockout due to adding too much calcium and magnesium.

Thanks all. Couple of clarifications: I had them in five gallon pots but moved them to these three gallon containers a few days ago. These are no larger than the ones I’ve had success with in that size.

I know it’s a nitrogen deficiency but the culprit is bad soil and consequently, poor nutrient absorption. When I dug them out to transplant the soil on the bottom was compacted and mushy.

I’ve saved a lot of money on reusing soil but after this, I’m going to track usage and limit soil reuse to a couple of cycles before tossing it.

You transplanted it from a 5 gallon pot to 3 gallon pot? So you transplanted her into a smaller pot?? You should always avoid transplanting in flower. It can cause a lot of issues. Was your plant like this before you transplanted it?
