Soil PH was off, Flush Performed, Leafs seem to be getting worse - Help Please

Indoor
Medium: Fox Farms Ocean Forest
Light: 600W HPS
Cycle: 12/12
Strains: C99, Master Kush, White Rhino

I was having some issues with a few spots on leafs. I did a soil test and my Ph was low (4's). I flushed the plants and got the soil PH back up (6.5). However my leafs seem to be looking worse. Really need some advise on what to do before I lose this grow =(

I think it's a calcium deficiency. I flushed the plants 2 days ago. Soil is still moist a few inches down so I don't want to water again until at least tomorrow. I have some calmag plus. Should I water with that tomorrow?


Thanks in advance

ok i would try a little cal mag//but you need to be carefull when you change your ph to quickly it may shock them.... that will make the leaves worse before they get better!! good luck bro hope this helped in the future i would only go up .5ph every water till you get it where you want it

did you measure ec run off if thats good and ph is good be carful on the watering dood i got major dramers my ph is 4.5 in coco i cant even get it back up 5th grow in a row bang on 4-5 week ive got rhino and power plant running know

Well the plants still seem to be growing ok. The buds are fattening up every day. But the worsening leaf condition worries me.

Don't worry, we're still here.
Can you toss up more recent pics if you got 'em?

From your OP, I would suggest top dress with a handful of crushed dolomite lime, let it get watered in good, and just keep your water at 6.5 for a week or more, then check your soil PH again.
I also wouldn't add any cal/mag just yet.
Look at the chart, and you'll see what I mean.

I just took those pics tonight.

If it was me, I would focus on the PH like I mentioned last post, then see if the spotting continues once you get your PH straight.
If it DOES continue to progress, THEN start back with your nutes.

Thanks man. I'll give it a try!

Good luck.
Keep us posted.

ocean forest has a very low ph and over time as it breaks down it'll get lower. when i mix my soil i add 1 cup lime per cubic foot of soil. so, for a 1.5 cu ft bag i add 1c pelletized lime and .5c powdered dolomite. the powder acts right away and the pelletized works over the long run.
