Mosquito dunks causing slow growth?

[967]

Hey all have a problem with extremely slow flowering. Can not understand why but last night it occurred to me I crumbled dunks in my coco. Could this be the problem?

Doing everything the same as always, yet buds are tiny, less than half the size they would usually be 4 weeks in flower

How do I check ph of coco without distilled water?

Pics won't help as they look pretty healthy, only a very minor nitrogen deficiency starting

Thinking the dunks are affecting the ph of root zone, possibly locking out potassium?

If it helps I've put the same product mosquito bits in my water for hours to let's it soak in before hand watering . I also have bits sprinkled on top of media , I do this in the warmer seasons only never noticed anything different with ph . When I think buds are tiny I think under feed or ph . Test the run off ppm /ph ?

Unlikely. The carrier for Bti dry products is usually inert.

I have used various products to no ill effect.

Some variables are hard to count. The water supply here changed for two monthes once, zero pH buffering (it was weak before). I barely caught it as I had become complacent and Floranova Bloom always dropped pH within 5.8-6.0.

re: keep looking and turn over every stone.

Why not brew up without feed and test pH? Corn meal is acidifying (if memory serves) and the Bits are large corn grit.

Hey I put so RO water in a cup ph was 5.7 after 24 hours with bits mixed in its reading ph 5.9 . Does this help ? I will test again after 48 hrs

You can eat BTI and have zero bad effects on ppl or animals. Only harmful bugs.

Post a picture of the whole plant or sectional upper, middle and lower shots.

If feasible of course.

What is the pH and EC of feed? What products? Watering regime?

You can slurry test with the RO if it is under 10-20ppm. Microbeman posted the proper technique in the Organic subforum, other wise Google "slurry soil test site:*.edu" without quotation.

EC readings of the filtered water will always test 0.2-0.8 EC or more above fed input. It varies on uptake, feed timing, etc. Without a baseline (I have yet to find an accredited source such as the numerous EC charts for ideal growth of other crops) this number is meaningless.
