I am thinking that we are just seeing full transpiration, and the plant trying to throw off/use as much water as possible. I am not convinced that there is a problem here.
I don't see either of those... but if you want to find a problem, google and the naysayers on forums will certainly point you to one. I would suspect that this is happening either in areas of particularly strong light or a breeze, and the plant is increasing the surface area of those leaves to take advantage of the ability in that area to throw off some extra water.
Great tips there T! I can't tell anything more either. The most important thing is the buds, are they growing? They sure seem to, keep on doing what you are doing. You are going to end up with a fantastic product in the end. Don't care about the beauty spots.
Keep up the good work, I think they are wonderful!
What u can expect to happen now is a little stagnation in growth. They start to mature and then they start to swell more that is the sign the end is near. Leafs start to get pale and lower leafs get yellow. But this is in a few weeks.
Great with a microscope, sure to get some nice shots with that. I'm about to order some new drivers and a bigger airpump I think.
Building a lamp for a friend of mine to replace a 600W sodium vapor lamp - this one has more lumen than that because u would need 492W of the Samsung LM301B to replace a 600W sodium vapor lamp so we will see what it does.
Spec's: ~500W (10x stripes) Samsung LM301B (3000K) and ~80W (4x stripes) Osram Horticulture, each 8x hyper red and 2x deep blue.
You are building the Deathstar my friend. What drivers are you using? I think I will go for the b models from Meanwell, with them you can pulse set the dimmer on them. Thinking of making a arduino program that sets rising and dawn on the light over a set time frame.
Btw, gave them water today, with the new Alg-A-Mic from BioBizz I got (for cal/mag) and they got a good pruning today. Think that was the last one...took away a bunch of leaves and the "popcorn" buds which got no light.
After letting them without water 1 day extra as usual I watered them today with boosters and some nutes. They look awesome AND now they got a very strong smell of Citrus and Rosmarine, but more in the Citrus way at the moment, really great because I never smelled such weed before.
I'm not sure how long they will need now, I just got 2-3 brown hairs on all plants....so I think they will need a few days/weeks more - or?!
