Dying plant, First grow, Need help!!! pt. 2

[JohnTheJoint]

I got great advice here before but my plant is in trouble again! Is this nutrient burn or nutrient deficiency? Thanks!

Hey JTJ, my eyes are bad ,but I can't see nothin in your pictures, with those lights on.

[JohnTheJoint]

Sorry about the bad pics, the problem is the leaves are very yellow and burned brown around some of the edges

deficiency of some kind - using Cal/Mag?

[JohnTheJoint]

I am, but I've had some trouble getting the nute levels right so it could be either high or low for all I can tell.

How old are they? Looks fine if this is organic I guess but if it's close to harvest looks like you should be flushing right now.. Some pants can finish flowering in 6 7 weeks and them buds will suck them leaves out just like that during so.. What your trichomes look like?

[JohnTheJoint]

I'm actually thinking today might be last feed before harvest and was gonna give half strength bloom nutes with calmag. It's Somango XXL, which has a smaller size and shorter life cycle. I started the seed on October 16th, switched to flower early in december (forgot to mark it), so this is week 5 of flower. What do you think?

[D.A.A.S.69]

You can't go by the seed banks, you harvest by the trichs, if your seeing clear ,your to early.

[JohnTheJoint]

Well I can try to take some better pics if you'd like, but basically the problem is a lot of the leaves are turning very yellow with browned tips. Do you have any recommendations? I really appreciate your help btw

Hey JTJ, that looks like bad nute burn ,to me, I wouldn't give her nothing but water now after looking at these pictures, maybe some molasses But look at the trichs on the buds not the leaves.

[Trichomefarmer88]

Now not the best pic but..... Don't look quite ready yet still alot of white hairs only see very few orange reddish hairs... Do you have any why to check the trichomes? Jeweler's loupe? If not you can go by the hairs on your buds... Not the best method but works! Now you're burning this girl up on them nutes it looks like... I agree with d.a.a.s.69 you need to flush your media an are you using molasses as your Sweetener?? I would flush it out with ph'd water and end it with a gallon of sweetener to help feed her some carbs cause looks like you burned all it out them leaves ... Happy growing am good luck... You're almost there help her threw it

[JohnTheJoint]

Thanks for the advice, I'll post the results when she's all done!
