Papa Munch
That old and easy feeling.
I've got 2 girls giving me problems right now. They are both Nirvana's, one is a Bubblelicious and the other is a No. Lights. They are in 3 gal. Airpots with Happy Frog, amended with dolomite lime and perlite. Soil ph has been 6.8. Temps have been 65-77, RH has been averaging 28-40. I'm using (2) Mars Hydro 96x3's at 24". I'm feeding AN Sensi bloom A&B per Tangs easy schedule. They got water w/ Calmag on the 28th, fed with 5ml./gal Sensi A&B, 4ml Calmag on the 24th, and a lighter feeding on the 19th.
The 2 Nirvanas fan leaves have been yellowing, starting with the veins and progressing into rust spots. This has been going on for about a week and a half now. They will be 6 weeks old tomorrow. The No. Lights top has been very wilted, limp and the top cola(s) have not shown much if any growth in the last week. I'm nearly positive that they are not overwatered. I wait until the pots are light and my A8 meter just barely registers 1 on the moisture scale.
The pic of them under the LED really shows the start of yellowing. The other pics included are under CFL light and look better but they are not better. This is progressively getting worse.
Limp, not growing, yellowing turning into rust spots....? Is this Calmag def? The closest thing I could find is manganese def or toxicity. Again...? Please help! What can I do to fix? They're still too wet to feed but when I can, I'm hoping I can get some direction. Thanks!
The tent. No Lights on left.
No. Lights limp as a noodle

PM-- hmmm, symptoms are not well defined, mate, so hard to make a call,... 6.8 is a bit high, and Fe starts to lock out fast by 7.0,... the droops-- most common suspect is over/underwatering, and I suspect that getting down to 1 on that A8 unit is indicating too dry,.. past a certain point, the soil doesn't moisten evenly, wet/dry patches can be created, and the water just channels around the dry patched as they become slightly repellent... Hefting them will help gauge this, if you know how a well watered pot feels, and a dry one,... if you have a wetting agent/water spreader, this will help greatly with evening out the moisture! The roots are traumatized, so aren't taking up water or nutes well, likely,... hence the generalized looking symptoms,...
-- don't let them get so dry Papa, some cycling is good, but not so extreme; yes, try the 6.0 pH feeds, ideal soil pH is mid-to-low 6's; as for the wetting agent, there are several on the market...I like Coco Wet... mild detergents are okay in a pinch for foliar, but don't use them in the soil-- too harsh and nasty! ..... can you get me a better pics of the spotting? I can't tell a thing in these pics,... certainly, the foliar won't hurt, just make sure it's dilute to about half recommended strength,...spray tops and bottoms of leaves, away from direct light, to avoid potential burning,... the wetting agent/water spreader is critical for foliar; it takes the surface tension out of the soln., so it goes on evenly and sticks instead of just beading up.. more surface area covered= more absorbed! It's via the stomata that stuff gets in by foliar, most of which are on the undersides of the leaves,... do it in moderate temps and RH too, as hot/dry makes the stomata close, and the solution dries too fast anyway,.. only in aqueous solution do the nutes get in, once dry, they're marooned on the surface! A slight rewetting with DI/RO water to redissolve the nutes is a good thing to do, just make sure she's fully dry by lights out to avoid potential mold/mildew issues,... 
.... good to hear they're happier already mate! way to improvise--:smoking:
