"Urgent Nutrient and Mite Help Needed!" or "The Infested and Malnourished"

• Strain: Cheese
• Method: Peat Mix, Clones
• Stage: 3rd Week of Flowering

Three weeks into the flowering stage of my first grow. Although all plants are from the same mother, treated the same, watered the same, cared for the same, I have what seems to be three different nutrient deficiencies/toxic buildups. This has been an ongoing problem since about a month ago.

Five days ago they were fed with 0.5 (FloraGro), 1.0(FloraMicro), 1.5(Flora Bloom) and some (edit) SuperThrive. About four days before that they were flushed with ph/down water. The nutrients are fresh. This is what they look like today.

----------------------------------------

First/Worst of them:


















Patches of brown toward the edges and tips of the leaves, and yellowing toward the middle. Purple stem/trunk and stalks. Fewer dead leaves. Smaller plants.

Middle/Not So Bad:

Overall yellowing, less dead/brown ends/patches, many dead leaves. Only purple leaf stalks. Big Plants.

OK :




















Pretty much fine except for a few brown spots here and there.

The spidermites (red) have been a problem from day 1. We have been fighting them with organic pesticides, BioGrow Pyrol and BioGrow Neem oil (as well as manual killing). I want to spray Margaret Roberts Garlic and Lemon Organic Pesticide tomorrow as they go into night cycle - what are your thoughts on that?

Please and thank you - any help would be most appreciated....

You saying you flushed your plants with a series of Flora nutes? If so, thats not a flush...thats a feeding. You need to flush them with plain ph'd/chlorine free water for several days then start feeding again. As for the spider mites...I just had a bad infestation in my flower room (had 200+ plants in there at different stages of flower cycle. I cut as many fan leaves of as I could and used a pyrethium (sp?) fogger. Then fogged again 10 days later to catch all the mites that hatched from eggs on the leaves. Then I spray with a Pyrethium (sp?) based spray from foxfarm called "Don't Bug Me" . It seems to have workedpretty well. I'm no expert by any stretch of the imagination but this has worked for me. Here is a pic of my plants after treatment for spider mites...good luck

hey there cybertrash welcome to RIU...are u useing tap waterwhen u flush/feed??? also whats ur PH??.....hey tat2ue those plants look like there loving life, what strain?
