To freak or not to freak? thats the freakin question

Ok so I am not sure if I have a problem or not so I posted here in general. I woke up this morning and found the lower leaves on both my big plants turning yellow on me and acting like they are wanting to die. but each plant has own issues sooo...

Plant 1)Upside down taco leaves( only a few), lower yellow leafs(just 3),purpling of stem at nodes.

Plant 2)purple stems in spots moving into leaf veins(minor amount)cold maybe??,orangish colored leaf tips only(newer leaves),really yellow lower leafs(4 of them), and weird spots on leaves.Dont look burnt to me or a bug problem.

setup)organic choice MG soil(brown bag),400w MH, No nutes except for bat guano(I make a tea),bagseed, 6 weeks old, topped and LST.. PH is roughly 7-7.5 but that shouldnt cause any def or lockout right??
I usually water with the mex guano tea for vegg like once a week. I watered with only water just 2 days ago with a capful of H202 with one gallon of water. Do you think I flushed all my nutes and since they were used to being fed every time, now they are starving? If so how can I nute them without over watering since my soil is still fairly moist under surface layer?

I have been up reading for 3 hours with no luck but a whole bunch of mixed emotions and ideas. There are so many different problems that share the same common symptoms its crazy. Any help would be greatly appreciated. Thx RIU FAMILY

Leaves just now did this to me. Other than that I have had no problems really.


PIC ORDER, yellow leaves, taco, taco2, spots, purple/red veins

bump bump..

they need a little nitrogen. just a little.

Does the MG have time release nutes? If so, transplant immediately into a different soil making sure you rinse off all the MG.

thats what I was thinking but wanted a second opinion b4 I did anything and fucked up. Will this help the taco leaves too or do I need some P? Also is guano a decent source of nutes by itself? Thx again man. I just fed too and dont want to over water, should I wait?

^that and a slightly lower ph, sure 7.1+ is doable....but 6.5 to 6.7 seems to make the plants alot happier with less yellowing with my experience.

No time released nutes, at least nothing major all levels are organic and super low levels(almost none at all really)

FDD is right. Just get some nitrogen fertilizer.

MJ uses all the nitrogen in the soil pretty fast. I'd say in two or three weeks in a pot that size.

cool. Any ways to lower ph without chemicals in mind? I use distilled water which reads at 7.0 on 2 diff meters. But soil says 7.5.....

Its a 5 gallon bucket. Can you point me in the direction of a good cheap NPK tester that you KNOW works? thx

save your money. Just get some fertilizer. You don't need fancy equipment to diagnosis maryjane problems.

Do you think bat guano is a reliable source of N on its own?

i don't know what causes the taco leaves. when mine do that i ignore it. not the best approach, i know.

guano is good. if used dry make sure to mix it into the soil really good. i would wait to fed. over watering is a bitch to fix.

cool thats what I was gonna do was wait and ignore the tacos. Plant seems heathy other than those tacos. I bubble my guano in gallon jugs for 6 hours than sit for 18. Shake well and use.

I have used lemon juice in the past to lower my ph levels. a little goes a LONG way tho, so start with about 1/4 tsp per gal and go from there. of course some PHdown is the best. it's only about $10 for a quart online and worth every penny
