Basic grow

Hi all, It's the end of week five, the first week of flower, and things started well but ended poorly. Temps were steady at the beginning of the week and I started her on flowering food regime. .25ml of CalMag and .5ml of bloom, grow and topmax. Starting gently. She seemed happy enough but then we had a mini heatwave. Things hit a max of 32.5 degrees down to a min one night of 16 when I forgot to turn my fans off in the dark. Still she seemed to take it OK so on the next feed rotation I upped her nutrition to .5 of grow an 1ml of bloom and topmax. Things went downhill the next day. Spots on her leaves and signs of deficiencies! (See questions/pics) And I believe we have lockout 🤨 I took measures. I put her in the bath and flushed her with 10l of pH tested water, 1l at a time and testing the runoff each go. In the last liter I added a teaspoon of Epsom Salts and .5ml of CalMag. She's now back in the tent with 2 fans on her to prevent any fungi coming and once she's dried out I'll go back to feeding her. Other than a few ugly leaves she's looking quite bonnie. She's still very squat and I could no doubt take off more foliage and even the low buds, but I'm happy to let her do her thing. So that's all for now Boys and Girls... Tune in next week, same bat time, same bat channel for another new (and hopefully more successful) exciting episode!
