hey, anyone have any insight as to whats going on? my bottom leaves keep turning yellow with a dark middle vein, dark lesions appear and they eventually die. I've tried everything i can think of. I forget what kind of deficiency this might be, but any quick solutions would be great, i'd like to start flowering them real soon.

i tried mixing a teaspoon of epsom salt in a quart of water, this helped the leaves out alot but there are still some asshole leaves that keep dying on me. help please!

actually that helped a bit...new question. Anyone know if its ok to mix epsom salt in the same watering as nutes? or is that overkill? im growing my plants in hempy buckets so i want to get all those nutrients to them, but i dont know if id be overdoing it by mixing epsom salt and nutes together.

yeah im afraid of doing that tho cus i know it needs at least once a week of just water to flush out any buildup. so i figured putting salt in those waterings wouldnt be too good.

so i got some pictures of the leaves in question. the first one is a leaf that i pulled off, it was done for anyway, i hope you can see if easily, its yellow-brown, with dark spots and curled at the tips. same with the second picture. the third and fourth shows a couple of leaves with really dark middle veins, theyre also starting to yellow. WTF is going on?!! i really want to start flowering them but not without fixing this problem.

Jeez, your plants look terrible. It appears that they are not getting enough light (resulting in awful stretching), and the leaves are very droopy, possibly indicating over-watering. How often do you water them? And what sort of nutrients are you using, and in what concentration?

theyre definately getting enough light, im using a 400w hps in a pretty small but well ventilated room. one of them is definately overwatered, i gave up on it, but the others arent that bad. i know everyone says to water every 2-3 days, but i really dont need to water until like 4 maybe 5 days go by and im just using perlite and vermiculite. i know they dont retain water well but they have been so far. i water with half strength 10-15-10 schultz liquid plant food whenever the perlite starts getting dry. i fixed most of the problem, i just dont know what the spots in the middle of the leaves are.

I used Schultz nutes the first time I grew like 10 years ago and had terrible results. In my opinion, Schultz is in the same category as Miracle Grow. If you are still vegging, 10-15-10 is not appropriate because it is too low in Nitrogen. You want something that is higher in nitrogen and lower in phosphorous and potassium. I use FoxFarms GrowBig and BigBloom and couldn't be happier. In addition to the macronutrients (NPK), it is rich in micronutrients and enzymes which your plants need to be healthy. I think you should flush with plain PH'd water for two weeks. In the meantime, get yourself some better nutes more suitable for growing marijuana. After the two-week flush, start feeding the new nutes at half-strength and see how things look then.

where can i find some good nutes that arent in a hydro store...there arent any of those around me. also, they're big enough where i want to start flowering, could i just switch right away from the flushing to some nutes suited for flowering?

You can order nutrients from any one of several online stores. I use HTG because they have great prices and have a great reputation amongst users of this forum. They are very discreet, shipping in plain brown boxes with no indication of what's inside. You can send them a money-order if you are concerned about something showing up on your CC statement (that's what I do).

Your plants shouldn't get too much bigger if you flush for a week or two before starting flowering. But keep in mind that, during flowering, they could double or even triple in size.

You can use the TigerBloom without BigBloom, but not the other way around. Keep in mind that BigBloom is not a suitable fertilizer on its own; it must be used in conjunction with GrowBig or TigerBloom. They only cost about $12 per QT, and for a few bucks more you can get the triple-pack which includes 1QT GrowBig, 1QT BigBloom, and 1QT TigerBloom.
