Curling leaves

Growmorestarted grow question 6y ago

Why are my bigger fan leaves curling? Don't think is heat stress or overwatering. Maybe my PH was a little higher for few days like 6.3 6.5 . What do you guys think it might be pleae refer to last pic in week 3 of my diary.

Like FruitGrower said could be RH. If it was me I would lay-off the ferts and run corrected ph water only the next few times. Almost too green for four weeks. Plants look beautiful and are healthy. I would just try that. Won’t harm it if it doesn’t work.

They could be lacking in moisture in the air. What is your rh? Important to keep cannabis humid through vegetave stage, get yourself a little humidifier.

Hi there! Do you know what is your humidity in growing area? I think your VPD might be off and it is temperature to humidity ratio. So if you have 29C you should have something like 70-80% RH for optimum vpd for this stage of growth

Leaf damage/discolouration The yellowing is from an earlier issue but now I'm noticing brown spots and the leaves curling up, some getting crispy-ish. I recently lowered the lights a few inches, knowing I was pushing the safe limits. Is this from the lights or is more likely a nutrient/pH imbalance?

Dry brittle leaves Discoloured older leaves curling up at the edges and turning dry and brittle. I think my problem is over or under watering. I've been very careful to avoid overwatering so I'm leaning towards the latter but what I've read online suggests dry/brittle means overwatering. Thoughts?

Fan leaf deficiencies during flower. To cut or not to cut?Day 85 Update: G13 has a ton of fan leaves turning fast. Pretty sure it's a PH issue. Should I wait until they're dead to trim them off or get rid of every fan leaf that is affected more than 50 percent of the leaf?

Any idea why the leaves are curling inwards like they are in the last two photos? Is this because it's too hot, or am I giving it too much water? Should my fan be blowing on the plant itself, or the 150-watt light? Thanks.

Everything seems to be OK except one thing (week 3). I thought using the greenhouses at night made this, but it doesn't. When I check the plants early in the morning, their leaves are slightly curled upwards, just along the edges. As the hours go by the leaves flatten. Any clue?
