    Default Heat Stress During Heatwave?

    Hey guys, I got 3 xxl blue amnesia on the go. They are in the flowering stage atm. After a couple weeks of mostly overcast weather in the UK, the past few days it's jumped from low 20 celcius, to high 20s/low30s. I've noticed a couple fan leafs with burns on them:

    Also here is the previous weather:

    I did a quick search on the subject. Seems like indicas are more prone to heat stress. A couple solutions seem to be:

    1. increase shade. This one seems the best, however they really haven't been getting enough light recently.. So what should I do here? take them in to shade during the hottest hours? How much light should I aim to get them minimum?

    2. kelp extract for roots

    Really not sure what to do here, they are not far off from finishing now I imagine (first ever grow here btw), so don't want to lose them now! Thanks in advance

    I’m growing outdoors and the temps are in the 90s with low humidity. They’re growing like a WEED! Out of concern for the high temps and low humidity I move my five plants into filtered shade / full shade at about 7:00 pm. They’re getting about 13 hours of full sun every day and they seem to enjoy the change. I am a FIRST TIME grower so this just my $0.02 worth. You may want to get a receipt.
