You're sure that they're flowering? Perhaps they are just showing preflowers. At 4 weeks old it could be preflowers. Better pics would help.

If you correct the problem they will grow out of it. The scorched leaves will never recover but new growth will be fine. Give them time. When they get bigger with nice new growth you can cut off the damaged leaves.

I've never had a problem adding a cup per 5 gallons. It is time released. The lime doesn't break down all at once. I add the cup to the original mix then top dress at flip to flower. My plants are in the 5 gallon pots about 4 months, and yes... With no lime and growing trees it gets way to...
I've used sunshine 4 for 15 years... The only thing I add to it is dolomitic lime. One cup per 5 gallon pot. The peat gets acidic late in grows and the lime counteracts that. As far as having coco in it... I'd read the label again because my sunshine #4 has no coco...

I mix it in the soil and top dress once when I flip to flower. So between those two things and a small amount of calmag once a week I have no problems and don't pH my water, which comes out of the tap at 7.4. If you have no dolo lime in the soil I would top dress a tablespoon per gallon of soil...
You can add dolo lime to an existing pot. Just top dress it and water it in. It takes a couple weeks to begin buffering the soil. Next time mix it in before planting. I use a cup of dolo lime in 5 gallon pots. I grow in sunshine #4, very similar to promix. I also add a small amount of calmag...
Budding out nicely. This is the first plant I've grown outdoors. After 15 years of doing this indoors. I'll definatly have one or two every year. It been fun and I learned things. Learning is always the goal! A branch of it was successfully pollinated as well.

The outdoor is coming along. Hoping it will be done by first frost, but it can always go in the greenhouse if it needs more time.

Cut light back and repot. Those 10 gallon pots should hold enough water for two visits. The plants will concentrate on root growth with the repot so above pot growth will slow anyways.

Yes they'll have it at hydro shops. A huge 25 pound bag of agricultural dolo lime is like 20 dollars. And do foliar calmag to correct the problem in the short term.

The dolomitic lime is time released. It won't fix your calmag problem overnight but will gradually buffer your pH over time. I usually add it by mixing it into my soil before planting and I top dress a few weeks into flower.

Well thanks! I like to be well rounded, to have the ability to make any grow work in lots of different conditions with lots of variance in equipment.
Being stuck with one style is limiting I think. Every grow has its own challenges and expanded ones knowledge!
