<span class="link_user">@Normanite420</span>, dont just take my word for it, keep a close eye on them, do the hand test even... but keep an eye on them...
<span class="link_user">@Normanite420</span>, nah, just add it to your feed, from what I've read you don't ever want to spray the buds or flowers. I've never used a foliar for anything yet, still a newb. Peace
<span class="link_user">@Wicked_Stix</span>, Thanks for your reply. I think my temps are pretty stable, so I'm not sure if that is the issue. I fed last night with Big Bloom and Cal-Mag, but I think I will try a foliar spray tonight to help address the issue, then start giving it to them in feedings/waterings as necessary.
<span class="link_user">@Smowkabowl</span>, Thanks! I am going to buy epsom salts tonight.
Since I just fed them, do you think foliar spray is best option? I wasn't sure since the plants are in flower.
I think <span class="link_user">@Smowkabowl</span> has the right idea on the purple leaves. I have personally dealt with 2 situations where the leaves turn purple. First is obviously genetics, second if your night temps get too cold it will lock out phosphorous intake and cause purple on the leaves. I assume that ph or lack of nutrients could cause it also, but I would think other nutrient issues would be visible as well in those situations.
<span class="link_user">@CRiSPrGrow</span>, I will probably go ahead and take the advice and move it down and keep lowering it down until I see signs of heat stress. I have been scared to do that over the last week due to topping and LST - didn't want to over-stress the ladies. Appreciate your input!
<span class="link_user">@CRiSPrGrow</span>, I have them at around 18 inches, which is what the manufacturer recommends for flowering plants. I've been worried about them burning. I will lower the lights if this is stretching. I thought it was normal growth. Thank you!
