I have arrived at several conclusions, recommend one :)

Alrighty. I posted on here a few days ago about my gro that's going on. I ran into some problems with a couple of leave's turning yellow and curling upwards, and one displaying brownish spots on it, while the remainder of the plants looked normal.

I received lots of good help, and was told it looked to be positively a nute deficiency, most likely CAL/MAG. It was also recommended to me to flush my soil as well.

So, with the advice I've received I have arrived at three possible options for myself and what I should do, please let me know which one is the best one for me:

1. I can flush the soil, adding the cal/mag on the final flush as per someone's recommendations and step-by-step guide that they told me on here.

2. The plants are relatively small, approximately 5 inches from the soil, so there's a big chance the roots aren't that large yet either. I can forget about flushing altogether, and just buy two brand new pots to put the plants into, and mix my own soil up with peralite and the proper cal/mag in it, and transport the plants into them.

3. When I bought the plants, the guy at the store informed me that he was pretty sure (although not 100%) that they did not add any extra nutrients into the soil, aside from what was already in the soil and a bit of peralite (which I could see anyways without him informing me of it). I went by the better to be safe mentality I see around here, and did not feed them for the first few days I had them, because I read several times it's better to underfeed than to overfeed. However, after the plants displayed the issues I mentioned above (yellowing, etc), I posted on here asking for some help. I actually got a bit frustrated and panicky, and added approximately 1.5mL of "Miracle Gro All purpose plant food" (which someone from here told me to get as well) because of the issues and what the guy had told me. I watered the plants with it as normal (they needed watering too so it was the right time) and sprayed the leaves with the. Today, a day later, I could almost swear that the yellowing seems to have stopped, and on some of the leaves looks a bit better. I cannot say this for certain but I am almost positive it has had at least a tiny impact on the plants. Based off this, for my final option, should I just ignore the first two options, and keep monitoring my plants after I fed them with the nutrients for the next few days and see?

Please lemme know which one is the best option for me at this point. Thanks a lot

What are you using for light and how close? If the problem is correcting itself then it might not be heat stress but usually with leaves turning yellow and curling upward is caused by heat stress (light being too close to the plant). Where did you "buy" the plants? Are they clones?

The plants are 100% female clones of Hawaiian Punch purchased from a Government of Canada run legalized Marijuana shop.

The lights I was using up until today weren't powerful enough to cause what you're describing from what I've seen and heard around here. I was using only two CFL 15watt bulbs thinking they were the 60w equivalent. I was told this was wrong and today I went out and purchased 6 more, so I am now running with 8 CFL lights, each 15W, approximately 5 inches above the plants.

Here are pictures of what was happening:

Also I posted these pictures and someone said it was definately a cal/mag deficiency.. So now I'm getting conflicting reports
