That's interesting.
A couple of the plants from my "BOG Mix" only have leaves with 3 blades and 2 tiny stubs... even in flower!
Heat stress can stunt your plants and make them transpire so fast that you have to really keep up with the watering.
Get the temps below 80 -stick your thermometer right at the canopy- and give a silica supplement. I have temp problems in the summer in my veg room sometimes- up into the 90s even- but using the Silica Blast they seem much happier.
stinkyattic Reviewed by stinkyattic on . Impact of heat stress during veg? Hi, I have some young ones, about 3 weeks old, under a 400watt mh lamp, they are about two feet below it, with a six inch personal fan blowing over the canopy. They are showing signs of heat stress as some plants have only developing 3 or 4 blades per leaf. Other than that though the plants seem very healthy with bushy, vigorous growth. Is this going to create signifigant problems? The flowering room has much better temerature control and will stay in the appropriate range (below 80) Rating: 5
