Flowering advice?

I've just switched my lights over to 12/12, and I need to know how to handle the next few weeks in terms of feeding and lighting. The plants are Sunset Sherbet and Vanilla Kush, both Indica dominant in appearance to my novice eye. I don't know how much stretch to anticipate, or how much I need to feed for it.

When should I start winding down the nitrogen and switching over to something more appropriate for flowering? The plants are in 5 gallon grow bags with FFOF. 56 and 46 days veg. I'm currently using a combination of 5ml Grow Big (6-4-4) and 10ml Fish & Kelp emulsion (2-3-1), along with 2ml Silica Blast (0-0-0.5). I also add a small amount of molasses and Root Ruckus for microbial health. I have Tiger Bloom and Big Bloom on hand, and I can also top dress with alfalfa or bone meal. I'm not against using the Fox Farm liquid nutrients, but I'd like to keep them to a minimum if possible, especially if I have an effective organic alternative on hand. What would you do?

Also, I currently have 2x SF-2000 in a 4x4 at 80%. I know flowering needs more light, but when and how much should I increase it?

First few weeks just stick to your grow nutrients
Once stretch is complete, incorporate flower fertilizer incrementally reducing veg nutrients

Edit: after looking I wouldn't suggest trying organics with FF anything

I have the same light and room setup but to your question about stretch-it varies significantly even amongst phenos, but generally indica stretches less.

Once he started using Silica in his soil, his ph is wack and well he says he knows what he is doing

I've never said "I know what I'm doing." In fact, I would be the first to tell you it's the opposite. I was legitimately asking for your reasoning above, and didn't get a serious response. If there's a reason I should or shouldn't be doing something, or if the plant is unhealthy, I would like to hear more. I'm open to feedback, that's why I'm posting in the first place.

Might want to get the plant to the right healthy before flowering it.

Just a suggestion

What's wrong with it? I'm legitimately asking for help here, and a little more detail would go a long way.

Looks like you have 2 issues.

1 over watering
2 the new leaves are coming out thin and spindly. That is a pretty classic potassium excess.

i would not flower the plant from right

don't go too hard on the light too early in bloom, and control the ppm/ph of your runoff frequently

That particular pic in the first was taken yesterday after missing a watering and a bunch of pruning. This is the same plant this morning after a chance to recover - should I still be concerned? I think that it looks like the symptoms you've pinpointed may have improved, but I could well be wrong.

Yeah those evil evil salts. I can't believe they are even legal. Who wants bad tasting flower that burns black?

My understanding was that they can build up and harm the plant, so I was just trying to minimize that. I'm trying to learn, same as everyone else. I've been reading from a lot of different sources, and may well be getting bad information or drawing the wrong conclusions. If my reasoning here doesn't make sense, I really do want to know why.

I grow in coco with dry salts. Feeding to runoff prevents salt build up.

Feed your plant. Don’t overfed and it won’t build up simple as that No matter what sort of feed your using.

yes large runoff is the key in hydro mediums

ideally you want to measure the same pH/EC values in (feed) and out (runoff)
it would mean you dont let any nutrients "salts" accumulate in the medium

If you measure the first little run off wouldn't you want it lower? I get your saying you should water till it's the same as going in but at first seems like good sign if lower. Correct?

yes ideally the runoff should be a bit lower than the feed, like 0.1mS, with a small increase in pH
its the perfect spot but it can sometimes be hard to get if the room isnt sealed with temp/rh fluctuating from a day to another

large runoff will erase imperfections
personnaly i recover the runoff in a second reservoir and by measuring ph/ec i easily know if i'm in the right spot
i adjust ph (and EC if needed ) and transfer it again to the main res to feed the room
