Getting down towards last weeks of grow. Going great, loaded trichomes, top genetics there. Getting nervous, getting brown spots some leaves (not lot) I think may be calcium deficiency possibly ph off, because I do use cal-mag every watering. Should I be worried? Other question even though I have done much defoliation as they grow they have become very thick. Should I try to trim leaves in middle to get ventilation in middle? Again much trichomes wanted to get them into trim bin, if I cut leaves to get air circulating will they go to waste? This is 3rd grow need keep them ripening, greatly appreciate help. One last question. I am using a 34 watt 4ft. UV/B light for 2-3 hours a night in conjunction with a 450 watt Mars Hydro TS3000 (Enhance trichome production, working) this is 18 inches from canopy. Is 34 watts too strong? Have great day Thanks.
That doesn’t look like typical calcium def… almost looks like nutrient splash but I’ll tag @Covertgrower for you.
Can you take a pic of the fan leaves instead of just the bud? Kinda looks like leaf Septoria but hard to tell
Thanks could be, I had flushed before incident. Ph was low 5.6, possible lock. Other thoughts someone said septoria.
I agree. Looks like something got sprayed on it.
I do the usual pre-flip and 3 week defoliations. After the 3rd week I do maintenance. I remove large fan leaves when they get big, shade buds or I need to open up a plant again.
Thanks, all help is greatly appreciated. This grow going be awesome. I was experimenting with different combos that may have caused that color changes on leaves. Potential 2 trichome enhancers interacted. Also using a 34 watt uv/b 4 footer. ( guess they recommend 20 watt) use that for 2 hours at night in conjunction with Mars Hydro TS 3000(450 watt LED) keep in touch Thanks….
