Here are some pics. Last night the leaves looked fine, but now they have brown spots Sent from my iPhone using Grasscity Forum
I’ve been using cal mag the whole grow:/ 1 tsp per gallon. I used 2 tsp of a 2-0.25-1 nute solution a few weeks ago then lowered to one tsp this week, watered in just once Sent from my iPhone using Grasscity Forum
I recently defoliated and FIMmed. Would this require more nutrients? Sent from my iPhone using Grasscity Forum
Unfortunately I haven’t measured PPM. I don’t have the tools to do it:/ but thank you for the advice Sent from my iPhone using Grasscity Forum
After you water 2 times and feed once with 1/3 nutrient solution work your way back up to full strength... Do it slowly
I prefer to only use tap water these days for it's cal-mag content, sometimes it's high enough to curb deficiencies in strains that always seem to give me magnesium issues (i only use Promix). Those spots look a little like calcium def and you should follow the above post using just PH water for a bit especially if you've been giving them cal-mag supplement..Iv'e seen some foliar feedings or spilled nutrient solution causes spots like that as well...good luck man
Thanks that makes me think it could be from me spraying lavender water on the leaves to get rid of bugs Sent from my iPhone using Grasscity Forum
I don't use lavender oil but i learned a valuable (and painful) lesson about using neem oil under light..i'm sure it applies to most oils...this isn't my plant but this is damage from neem-oil/ insecticidal soap put under lights..
If it were my plants i'd just wait it out.,no lavender stuff and PH water like mentioned above and nothing extra for the next few waterings and see if it clears up..rule everything out...it doesn't look too bad from the photo imo..
