First thing, I think you should correct some issues you have with language/concepts used so that it prevents any further misunderstanding:
When you say 4 baths, I suppose you mean 4 pulls. When you say bath, it makes it seem like an A/B extraction when you do multiple boils in acidic phase. Pull is when you mix the solvent with your basified mixture, and then separate the solvent.
Also, calling "jungle spice" is misleading. Jungle spice is what is called when you extract using an aromatic or generally less selective solvent such as Xylene/Toluene. Just because you have something of a specific color does not mean its the same as jungle spice. Color may mean many things:
IMPORTANT: spice color purity fallacy AKA is your dmt ok to smoke ? - DMT Discussion - Welcome to the DMT-Nexus
If you havent separated carefully and you believe you have lye/mimosa liquid droplets in your solvent, you should wash it as described in the FAQ, or if you already evaporated the solvent, you should recrystallize it, also as FAQ explains. These polar impurities could be why it tastes harsh (and/or the fact that you dont have an ideal vaporization method)
How did you consume the caapi extracts and the dmt, all together, one before the other, dissolved in acidic solution or capsuled, etc? If its capsuled, thats problematic. Did you ever have big success taking it orally at this dosage? If not, it could be youre just like me and you need big dosage when taking pharma. Next time try buying some actual caapi, brewing it yourself and throwing some DMT in there (smaler dose! test max at 100mg first), its way more effective than taking purified harmalas, specially if capsuled. Also if your supplier is the one im thinking (f visions), they have a history of bad business, I wouldnt trust them, extract your own rue/caapi or take whole brews better.
Do you weigh your dosages? If so, what dosage are you consuming? If not, eyeballing is very innefective so its impossible to take any conclusions unless you do weigh them.
One thing you might or might not have noticed, is that even with the same batch in same dosage, the experiences can change A LOT. I would really think that your problem is actually in dosage and smoking method, and also that your DMT is probably not clean enough (you consider "jungle" thinking its other alkaloids + DMT, but very possibly a bulk of your product is plant oils/impurities that were in the evapped naphtha). The fact you think your supposed jungle spice is somehow different is most likely IMO due to the fact that oils somewhat protect DMT during heating (in innefective smoking methods) and therefore it seems like it works different, since white crystals would be more exposed to heat and degrade faster if source of heat isnt controlled as in a good vaporization method.
One weird thing I didnt understand is that you said you first tried the supposed jungle product and then dried it.Dried it from what? If it was more moist, this means it had SOLVENT in it, you shouldnt smoke it before you are absolutely sure its completely dry of solvents.
Lastly, I think what you should do is: Recrystallize your stuff, get a scale if you dont, weigh proper amounts, vaporize either using an improvised convection method such as Inspirator MKII or buying a glass vapor genie and a torch lighter. Also in the meanwhile it wont hurt to just stop trying to smoke it for a while and dedicate to other things in life. This way it will start working for you, im pretty sure.
